A New Human Tapeworm (Taenia Confusa N. Sp.), An Entozoon, Probably Of Order Cestoidea, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

Somewhat more than a year ago a tapeworm was sent me which at first sight appeared decidedly unlike either Taenia saginata or Taenia solium. It showed the slender form and more delicate appearance of the latter, but was in length of segments even decidedly larger than the former species. Some notes were made at the time, and then, on account of pressure in other directions, laid aside to await opportunity for further study. This winter I received a second specimen which at once recalled the first, and on comparison was seen to be identical with it. A series of …

The Food Supply Of The Great Lakes; And Some Experiments On Its Amount And Distribution, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The subject of agriculture has received for many years the closest attention of scientific workers. Not only the character of the different products, their food value for different uses and in connection with the raising of different kinds of stock ; but also the value of the soil, the use of each element in it, the exact relation of each individual particle in the entire chain of biological relations from the unorganized matter to the saleable beef or pork, has received from the experiment stations of the country the most careful study. Every one of the pests, of the enemies …

Some Notes On Nebraska Birds: A List Of The Species And Subspecies Found In The State, With Notes On Their Distribution, Food-Habits, Etc., Lawrence Bruner

Papers in Ornithology

For upwards of twenty-five years the writer has taken an interest in our birds and made notes relative to their abundance, migrations, nesting, food-habits, etc., simply for personal gratification.

About two years ago, during a conversation in which the relation of birds to horticulture incidentally arose, Professor F. W. Taylor suggested the advisability of devoting a portion of a succeeding annual report to our Nebraska birds. With this object in view both the professor and the writer broached the matter to other members of the Society. Several at once not only became interested in the matter, but suggested its early …

Bulletin No. 40 - The Economic Production Of Pork, A. A. Mills

UAES Bulletins

This bulletin contains the detailed results of two years' work along the lines indicated, and a summary of the work of four years as far as it has been carried along these same lines.

In the summer of 1894, twelve lots of pigs were selected. They were purchased in Cache valley, and were a fair average of the pigs raised here. It was originally intended to put three pigs in each division, but just at the time of beginning the experiment it was difficult to procure enough animals of the proper age and size, so that the lots contained but …

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 …

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 …

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.

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, …

Bulletin No. 36 - Relative Value Of Corn And Oats For Horses, A. A. Mills

UAES Bulletins

This Bulletin reports the continuation of the study of the best nutritive ratio for horses under moderate work. The experiment was so arranged that a direct comparison could be made between oats and corn as the principal grain ration. The work was planned by Prof. J. W. Sanborn, who was then Director of the Station.

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 …

Bulletin No. 30 - Narrow Vs. Wide Nutrituve Rations For Horses, J. W. Sanborn

UAES Bulletins

In the third annual report of this Station (1892) the result of feeding wide and narrow nutritive rations to horses was given. This trial was favorable to the narrow nutritive ration. This ration was made up of clover, oats and wheat", while the wide ration was made up of timothy and corn. The trial ran through the summer, when the influence of what has been termed heating food, like corn, might be less effective than in the winter season. Many believe that the more varieties of food given the better the result, as the palatableness of food, it is claimed, …

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 …

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 …

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 …

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 …
