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

Covers the water supply and irrigation with respect to farming in Nebraska in 1894.

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 …

Article Viii.-On The Affinities Of Leptarctus Primus Of Leidy, J. L. Wortman

University of Nebraska State Museum: Mammalogy Papers

Up to the present time but very little has been known of the existence of the peculiarly American family Procyonidae in any deposits older than the very latest Quartenary. Leidy has described and figured an isolated last upper tooth, from the Loup Fork deposits of Nebraska, under the name of Leptarctus prirnus, which has been referred to this family. The Museum Expedition of last year into this region was successful in obtaining additional material, which we provisionally refer to Leidy's species.

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).

Nebraska: Her Resources, Advantages, And Development, Joseph Garneau, Jr.

Nebraskiana Publications: Resources and Materials on the 37th State

Almost midway between the two greatest oceans of the world, its eastern boundary marked by the rapid flowing Missouri, the westernmost counties shadowed by the towering ranges of the Rockies, with the land of the Dakotas to the north and the great agricultural state of Kansas to the south, lies the garden spot of that vast and shadowy country (which but a few short years since was only known as The Great American Desert).

Today it is the State of Nebraska, the happy home of one million and a half of thrifty, industrious and prosperous people. In less than a …

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 …

THE occurrence in this region of Richardson's owl, Nyctale Richardsoni, seems to be entirely established by the recent capture of one in Lincoln. This is a long distance below its southern limit, and its appearance is something of a surprise.

A New Habitat Of The Black-Throated Rock Swift, Micropus Melanoleucus, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

As curator of the museum, I have just procured for the State University of Nebraska a set of bird-skins prepared during the past summer, among which are five skins that must be of interest to ornithologists. They verify the discovery made by Professor Lawrence Bruner of the University of Nebraska, that the White-throated Rock Swift builds and breeds in the precipitous bluffs around Squaw Canon, Sioux Co., Nebraska, and, what is more likely, throughout the Pine Ridge regions, as Professor Bruner has observed them also at Crow Butte, near Crawford, Nebraska.
