On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The distomes of cats have received special attention of late in the two papers of Braun (94) and Stiles and Hassall (94). The latter authors give a most admirable account of our present knowledge of a dozen allied forms, and record two, D. albidum and D. complexum n. sp., as found in cats in the United States. During the past year I have examined the cats killed at this laboratory, and have found neither of the forms recorded from the east. Distoma felineum, however, which Stiles and Hassall did not find. and which has not been reported hitherto for …

A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

Only two methods of estimating the quantity of plankton obtained in a haul of the vertical net are known to me. These two may be called the volumetric and the gravimetric. Both have been used by observers in various parts of the world, but so far as I know have never been comparatively tested in order to ascertain the relative value of results obtained by the two. The experience of the past year has shown some disadvantages in the first method, while the second has certain evident objections which rendered its employment in this case out of the question. In …

The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

This article has been written for the general information of those engaged either on a large or on a small scale in stock raising in our own state particularly, and, while not intended to be a complete treatise on the subject, it includes references to those parasites which seem to be the most important or most likely to be found within our borders. The parasites of cattle, sheep, horse, hog, dog, cat, and man, which have many species in common, form the subject of this paper. The parasites of domestic fowl are, however, quite different from those considered here and …

Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893, Per Axel Rydberg

School of Biological Sciences: Dissertations, Theses, and Student Research

Rydberg (1860–1931) was born Sweden and emigrated to the United States in 1882, first to mining camps in upper Michigan and eventually to Wahoo, in Saunders County, Nebraska, where he taught mathematics from 1884 to 1893 at now defunct Luther Academy. In the summers of 1891-1893, 1895, and 1896 he was a field agent for the United States Department of Agriculture and collected plants in Nebraska, South Dakota, Montana, Idaho, Wyoming, and Colorado, and specimens from those and other trips are in the Bessey Herbarium at the University of Nebraska–Lincoln, which house what is now known as the Charles E. …

The Asiatic Lung-Distome In The United States, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In 1893 I reported the occurrence of the Asiatic distome in the lungs of a cat examined in Ann Arbor, Mich. This was the first reported find of this species on this continent, and the possibility of its being a permanent guest in this country was so serious that I urged a careful examination of all cases of lung-parasites in the domestic animals, with a view to ascertaining whether this might be an isolated instance, or whether the parasite was actually established within our land, for it is true that the Chinese, among whom the parasite is very common, regard …

Water Supply In Nebraska, O. V. P. Stout

On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes (1895), Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The distomes of cats have received special attention of late in the two papers of Braun (94) and stiles and Hassall (94). The latter authors give a most admirable account of our present knowledge of a dozen allied forms, and record two, D. albidum and D. complexum n. sp., as found in cats in the United States. During the past year I have examined the cats killed at this laboratory, and have found neither of the forms recorded from the east. Distoma felineum, however, which Stiles and Hassall did not find, and which has not been reported hitherto for the …

The Food Supply Of The Fish In The Great Lakes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

When the early settlers made their homes along the shores of the Great Lakes, the waters of these inland seas teemed with fish. A cheap and apparently inexhaustible supply of food lay within easy reach, and they drew from it unstinted, nor was it strange that, with the increasing population and ever-widening means of communication, delicacies so tempting as the whitefish and lake trout were eagerly sought after in the markets of the neighboring cities, and that the ingenuity of generations of fishing folk was taxed to invent means of securing the fish-until finally, in the face of a growing …

A Second Case Of Distoma Westermanni In The United States, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In a previous number of the Veterinary Magazine, I have given an account of the discovery of Distoma westermanni in the lungs of a cat at Ann Arbor. The importance of the discovery within our country of this dangerous parasite. so common in the East, was emphasized, and an appeal was made for more information as to the presence of lung distomes in various hosts in the United States since, as stated (p. 357), “there is no need of emphasizing the importance of obtaining accurate knowledge as to the extent of the infection among animals, and even man;” . …

Report Of The Zoologist, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In the report of last year was given a full summary of the present state of our knowledge concerning the parasites of man and the domestic animals. It is the intention of the following pages to review the parasitic fauna of the state of Nebraska so far as it is definitely determined, and also to include a list of some species reported but not accurately identified. The second section of this report presents a brief description of some important parasites not included in the group of worms, and hence not mentioned in last year's report. I shall omit all parasites, …

Flora Of Nebraska: Introduction; Part I. Protophyta-Phycophyta; Part Ii. Coleochaetaceae, Characeae, Charles E. Bessey, Dealton Saunders, Albert F. Woods, The Botanical Seminar, University Of Nebraska

School of Biological Sciences: Faculty Publications

The Vegetable Kingdom is in other words the plant world, or the aggregate of organisms called plants. It is co-ordinate with the animal kingdom, and these two include all forms of organic life on the earth. It is not possible to define precisely the line which separates the lower portions of these two kingdoms; we may therefore regard them as simply branches of one great group, inseparable below, but widely divergent above. In attempting to separate plants from animals the most we can do is to bring together those characters which separate the greater number of plants from animals, and …

Some Notes On The Biological Relations Of The Fish Parasites Of The Great Lakes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

A pond or small lake furnishes few variations in depth, temperature, current, or food, and hence the life in it is comparatively uniform. Nowhere else in the world is there found such a continuous body of fresh water as in the Great Lakes. They afford, in themselves alone, an area of water one-fourth greater than that of the state of Nebraska; or, considering the streams and minor lakes within easy reach, no doubt the area is twice as great. Furthermore, there are found here conditions of temperature, depth, light and food more nearly like those prevailing in the ocean. As …

On The Presence Of Distoma Westermanni In The United States, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

Last June a piece of the lung of a cat was brought me for examination, as it contained some foreign bodies which were unknown to the finder. A cursory examination showed them to be Distomidae, and more careful study seemed to confirm the first impression that, in spite of a few slight differences, they were specimens of the Asiatic Distoma westermanni. Being somewhat in doubt and not having the literature at hand, I sent several to Dr. C. W. Stiles, helminthologist of the Bureau of Animal Industry at Washington, D. C., who wrote that there was no doubt in …

A Preliminary Introduction To The Study Of Entomology, Lawrence Bruner

Department of Entomology: Faculty Publications

This book has been prepared for the purpose of partially supplying a demand that seems to exist here in the West for an elementary work on entomology such as can be used in the public schools and on the farm. It is not an original production, but comprises notes from many sources as they have been gathered by the writer and presented from time to time in talks to his classes in the University of Nebraska and before audiences at farmers' institutes throughout the state. The chapters on remedies and on apple and small grain insects have been compiled and …

Evolution And Classification, Charles E. Bessey

Papers in Systematics and Biological Diversity

As we have gathered up the scattered masses of botanical knowledge, laboriously wrought out by many isolated workers, and attempted to fit them together into a consistent whole, which should outline the structure of the temple of botany, we have found that the workmen have not always followed the same architectural plan, and have often used different units of measurement. With the increasing specialization so noticeable year by year there is a corresponding lack of coordination of work. To this lack of coordination, this want of unity of measurement, this misunderstanding of plan, we can no longer close our eyes, …

On The Parasites Of The Lake Fish: Notes On The Structure And Life History Of Distoma Opacum, N. Sp., Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

This work was done while a member of the scientific corps sent out by the Michigan Fish Commission to begin an investigation of the biological conditions in the Great Lakes. The work in 1893 was carried on at New Baltimore, on Lake St. Clair. My thanks are due to the Michigan Board of Fish Commissioners for the many conveniences placed at my disposal in carrying out the investigations on fish parasites, of which this is one result. To Professor J. E. Reighard, director of the party, I owe much for his interest and hearty cooperation in all matters pertaining to …

Symbiosis And Mutualism, Roscoe Pound

School of Biological Sciences: Faculty Publications

Symbiosis and mutualism, in the vegetable kingdom at least, are phenomena accompanying parasitism. Parasites have various effects upon their hosts, according to the nature of the parasite, its mode of life and method of attack. In some cases the host is quickly killed and the parasite becomes a sort of saprophyte upon the remains. In others the host lives longer or is only partially affected. In still others the host lives on side by side with the parasite indefinitely. A further development is attained in cases where the parasite and host not only live together, but are mutually beneficial, and, …

Cost Of Farm Crops, C. L. Ingersoll, S. W. Perin

University of Nebraska Historical Extension: Bulletin

The present bulletin is an inquiry into the" Cost of Farm Crops," as produced at the State Experiment Station, under the following conditions:

1. The crops were treated substantially as upon the farms ordinarily found in our state.

2. The labor was all charged against the fields at the uniform rate of 15 cents an hour for each man and team, or at the rate of $3 per day of ten hours.

3. Substitute the farmer anywhere in the state for the Experiment Station and charge his time and that of his team at the same rate, and the conditions, …

Notes On The Wing-Color Of North American Locusts Belonging To The Sub-Family Œdipodinæ And Its Seeming Relation To Climatic Conditions., Lawrence Bruner

Department of Entomology: Faculty Publications

One of the many features that have been noted in the study of our North American locusts during the past ten or a dozen years is the color-variation of the wings of the different species of lo-custs of the sub-family Œdipodinæ. As all students know who have had anything to do with these insects, some have yellow, others orange, still others red, and a very few have their wings blue. While this is true, perhaps it has not been generally noted that the presence or absence of humidity seems to have some influence upon these color-variations in the different representatives …

A Preliminary Report On The Worms (Mostly Parasitic) Collected In Lakes St. Clair, In The Summer Of 1893, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In the work done on the fauna and flora of Lake St. Clair during the summer of 1893, the group of Vermes was entrusted to the writer. The following is submitted as a preliminary report on the ground covered, the material obtained, and the results of this branch of the work so far as they can be seen at this stage.

Excluding the Rotifera, which were studied by another member of the party, the Vermes are represented in fresh water by three great classes: the Plathelminthes (Flatworms), Nemathelminthes (Round or Threadworms), and the Annelida (Segmented-worms).

American Work On Cestodes In 1893, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

An important advance in the morphological and systematic knowledge of the Cestoda has been made this year through two papers published by Dr. C. W. Stiles, of the Bureau of Animal Industry. They command attention not only since they emanate from an American worker, but also by reason of the methods employed. Heretofore it has been largely true that tapeworms were identified by their hosts and by their general appearance, and hence no branch of systematic zoology has been more confused. The same form from different hosts was the recipient of as many different names, and even specimens from the …

Insect Enemies Of The Small Grains, Lawrence Bruner

Department of Entomology: Faculty Publications

Although "corn is king" in Nebraska, our crops of small grains are not insignificant. The insect enemies of wheat, oats, barley, and rye therefore demand our attention nearly or quite as much as do those which attack corn. Accordingly, during the past year much time has been given to the study of this class of insect pests. While many of the species are identical for the different crops, the nature of the plants themselves being unlike, it necessarily follows that the mode of attack among these enemies must vary somewhat in each case. This being true, some pains has been …

Catalogue Of The Snakes Of Nebraska With Notes On Their Habits And Distribution, W. Edgar Taylor

Papers in Herpetology

The author has published in the proceedings of the Nebraska State Board of Agriculture a complete catalogue of Nebraska serpents including notes and descriptions of the adults and young. Since the preparation of this catalogue Prof. Cope's review of North American snakes has appeared. This together with the fact that the author has had time to review his own studies and add many other notes is sufficient excuse for offering the present catalogue.

In the classification we have followed Prof. Cope. The notes given are confined to the Ophidia or serpents of Nebraska. The range of the collection, which was …

On Certain Facts And Principles In The Development Of Form In Literature, L. A. Sherman

University Studies (University of Nebraska) (1888–1984)

Some ten years or more ago, on first attempting to teach English Literature historically, I found my attention peculiarly drawn to the differences of form between the sentences of More, Hooker, Lyly, and other early prosaists, and of approved stylists in our own age. Here was clearly an organic and sustained development, yet without scientific recognition of a single fact or principle of change. It seemed that something might easily be done towards determining the course of an evolution so evident and remarkable. But I had, or believed I had, no leisure for serious study of the subject, and found …

A Second Edition Of Webber's “Appendix To The Catalogue Of The Flora Of Nebraska." With A Supplementary List Of Recently Reported Species, Herbert J. Webber, Charles E. Bessey

School of Biological Sciences: Faculty Publications

PREFATORY NOTE.

The importance to Nebraska botanical students of the paper entitled an "Appendix to the Catalogue of the Flora of Nebraska," prepared by Mr. Herbert J . Webber, M. A., formerly assistant in botany in the University of Nebraska, now assistant in the Shaw School of Botany, St. Louis, warrants its republication by the University. It was published originally in the Transactions of the Academy of Science of St. Louis (Vol. VI., No. 1, March 12, 1892.) The present edition differs from the first only in the correction of a few minor errors, and the rearrangement of the index. …

A Second Report Upon The Native Trees And Shrubs Of Nebraska, Charles E. Bessey, Robert Bolin , Depositor

School of Biological Sciences: Faculty Publications

Dr. Bessey was then Nebraska State Botanist and “Professor of Botany, State University, Lincoln Nebraska.” The State University is now called that University of Nebraska–Lincoln. This document was published as a contribution to the knowledge of the native woody plants of the state. Several reports had been published previously each containing additions and corrections. This report contains a “Special Request” that asked readers around the state to send samples of native trees and shrubs to the author.

The report contains a classification list of the various trees and shrubs along with information about where they can be found. A table …

Report Of The Entomologist, Lawrence Bruner

Department of Entomology: Faculty Publications

In accordance with custom I present herewith a report as acting entomologist to the State Board of Agriculture. In former reports attention was paid to various insects detrimental to the agricultural interests of the state-sometimes one thing and at other times other things were considered. For the present paper I have concluded to give a review of the subject of the insect enemies of corn. In doing this - it is my intention to follow the plan adopted in Bulletin No. 14 of the Experiment Station, where I treated the insects injurious to young trees growing upon tree claims.

Since …

On The Determination Of Specific Heat And Of Latent Heat Of Vaporization With The Vapor Calorimeter, Harold N. Allen

University Studies (University of Nebraska) (1888–1984)

Joly, in 1886, and Bunsen, shortly afterwards, described two similar pieces of apparatus intended to determine the specific heat of substances by means of the condensation of water vapor upon them. The name given by Bunsen to this apparatus and adopted here is vapor calorimeter. Bunsen also intended his instrument to be used in the determination of the latent heat of vaporization of various liquids, and it is the object of the present paper to describe experiments testing the steam or vapor calorimeter in this direction. A rough experimental instrument was first constructed, combining to a certain extent the …
