The Morphology Of The Pine Cone, Charles E. Bessey

Papers in Systematics and Biological Diversity

So much has been said in regard to the morphology of the cone of the pine and its near allies that it would seem impossible as well as unnecessary to suggest anything further. However, the recent excellent summary in Coulter and Chamberlain's “Morphology of the Spermatophytes" of the many theories hitherto advanced to clear up the matter, and the conclusions reached by the authors named, show that it is by no means settled, and perhaps warrant me in presenting an interpretation which I have used in lectures before my own classes for half a dozen years or more.

On A Coccidium (Klossiella Muris, Gen. Et Spec. Nov.) Parasitic In The Renal Epithelium Of The Mouse, Theobald Smith, Herbert P. Johnson

Harold W. Manter Laboratory of Parasitology: Library Materials

In 1889, Smith published a preliminary description of a polysporous coccidium found in the epithelium of the convoluted tubules of the mouse's kidney. Several stages of the parasite were seen but the scantiness of the material left many gaps in the life-cycle. During investigations recently made to determine the mode of transmission of the Sarcosporidium of the mouse, Smith found a considerable number of gray mice, caught in the animal room connected with this laboratory, whose kidneys were abundantly invaded by this coccidium. This favorable opportunity of examining more thoroughly into the life-history of this sporozoon was utilized, and, as …

An Addition To The Parasites Of The Human Ear, Roscoe Pound

School of Biological Sciences: Faculty Publications

The list of Fungi which have been reported as parasites in the human ear is somewhat large. The number of species which are well identified is much smaller. The confusion long prevalent in the groups to which the ear-parasites belong, recently abated in the Black Moulds by A. Fischer, but still in force in the Imperfect Fungi, and the fact that otologists have not been much concerned with mycology nor always able to command the assistance of expert mycologists, have united with the inherent difficulties due to the effect of situs on the forms themselves to produce errors in determination, …

Reviews Of Current Botanical Literature, Charles E. Bessey

Papers in Systematics and Biological Diversity

A little more than a year ago at the annual meeting of the Society for Plant Morphology and Physiology, held in New Haven, a committee, consisting of Dr. Farlow of Harvard University, Dr. MacDougal of the New York Botanical Garden and Dr. von Schrenk of the Missouri Botanical Garden, was appointed to consider the question of securing better reviews of current botanical literature. A preliminary report was made by this Committee last June, a t a special meeting of the Society held in New York a t the time of the meeting of the American Association for the Advancement of …

The Modern Conception Of The Structure And Classification Of Diatoms, Charles E. Bessey

Papers in Systematics and Biological Diversity

In the revision of the Bacillariaceae for Engler and Prantl's “Pflanzenfamilien," Schutt has availed himself principally of the studies of Otto Muller and has given us the first clear conception of the meaning of the diatom cell, and its relation to the diatom filament. Starting with the filament, we regard it as the typical condition, from which the unicellular diatoms have been derived by the solution of the filament and the adaptation of the separate cells to an independent life. Diatoms are thus regarded as typically filamentous algae, and are no longer to be placed among unicellular plants. Accordingly their …

Some Results From The Study Of Allium, Clarence Elmore

School of Biological Sciences: Faculty Publications

During the summer of 1897, at the University of Chicago, I began a morphological investigation of certain species of Alliuin, being attracted chiefly by the often quoted polyeinbryony of A. tricoccum Ait. My results in the case of this species indicate that if polyembryony occurs at all, it is very rare. Besides A. tricoccum, I examined more or less thoroughly A. cernuum Roth, and A. Canadense Kalm, with the same general result. Seventy-five embryo-sacs of A. tricoccum were examined at the stage in which both egg apparatus and antipodal cells ought to have been found. The egg apparatus was …

Review Of The Phytogeography Of Nebraska. 1. General Survey, By Roscoe Pound, Elizabeth Britton

School of Biological Sciences: Faculty Publications

From the preface we learn that this work is the result of nearly five years of active study of the floral covering of Nebraska, carried on by the members of the Botanical Seminar in the Botanical Survey of the State. The systematic study of the vegetation of Nebraska was begun by Dr. Bessey in 1884, and has since been carried on by him and his students, all previous collecting having been more or less desultory and unreliable. The Botanical Survey was organized in 1892, and its work has been directed to the collecting of specimens and observations for a series …

The effect of certain methods of soil treatment upon the corn crop in Nebraska.

The Vegetation Regions Of The Prairie Province, Roscoe Pound, Frederic Clements

School of Biological Sciences: Faculty Publications

The vegetative covering of the North American continent falls naturally into two great areas, forest and plain. At first thought it would seem that these were primary phytogeographical divisions, but a comparison with the vegetative covering of other continents proves the contrary. Considered as a phytogeographical feature, the North American forested area is an entity ; from a floristic or formational standpoint, it may be analyzed into several distinct portions of widely separated relationship. The ground-tone of the great bulk of the North American forests is that of the forests of British North America, which are closely related to those …

A Preliminary Report On Experiments With Forage Crops, T. L. Lyon

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A preliminary report on experiments with forage crops. Covers sorghum, cow pea, hairy vetch, Canada field pea, non-saccharine sorghums, soybean, and rye.

Summary

Permanent grass pastures may be successfully substituted by certain annual forage plants.

A quick-growing variety of sorghum affords pasture fully equal to native or cultivated grasses.

Sorghum has the advantage of affording more forage per acre, and in being green and succulent throughout the entire summer. Its disadvantage consists in the necessity of plowing land for each crop.

One acre of sorghum will furnish pasture for ten cows twelve days.

The most profitable time to pasture sorghum …

Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey

Papers in Systematics and Biological Diversity

It is unnecessary for me to state at the outset what is evident to every botanist, that it is as yet impossible to present a complete phylogeny of the angiosperms. Phytopaleontology is too young a science, and the materials with which it deals are yet far too scanty to have given us direct evidence as to the phylogeny of all families of plants. No one can trace with great certainty from the fossil remains of plants yet discovered the genealogy of any considerable portion of the vegetable kingdom. It will be many a year before the direct evidence we so …

Note On Taenia Confusa, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

About a year ago I described in the Western Medical Review (Vol. I. pp. 35, 36) a new tape-worm under the name of Taenia confusa. Only two specimens of the form were available at that time and I have not been successful in obtaining others since then. During the past 'year, one of the students in the Zoological Laboratory of the University of Nebraska has been conducting a careful investigation of this form and one specimen has been entirely sacrificed to that purpose, In advance of the publication of his thesis it seems that I should make a short explanation …

Zoology In The High School Curriculum, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

A long time has elapsed since Bacon gave to the world the sound advice that “ we should accustom ourselves to things themselves.” Little by little this idea has gained ground, until now it is recognized as a general principle in every grade of educational work and in widely separated departments of study that contact with concrete objects is far more inspiring and thought-producing than the mere scanning of black marks on a white page. So far as natural science is concerned, the varied training which it affords has been abundantly discussed before this association and elsewhere. To be sure, …

Studies On Nebraska Parasites, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The intimate relations in which domestic animals stand to man have always made the transfer of parasites from the one to the other a matter of much greater probability than exists between man and the other forms of animal life. It is but natural that the most common species of human tapeworm come to man from his two chief sources of animal food-beef and pork. The chances of accidental infection, however, are evidently much greater in the case of those forms that are intimately associated with man, and hence clearly greatest in those he holds as household pets,the dog and …

Animal Parasites Of Nebraska, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The report submitted this year consists of two main portions: the first a short study on the numerical frequence of parasites among the dog, cat, and chickens of Nebraska, and the second of several brief accounts of new and important parasites discovered within the state since the publication of the last report.

A Biological Examination Of Lake Michigan In The Traverse Bay Region, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

During the summer of 1893 the Michigan Fish Commission entered upon a biological study of the Great Lakes by maintaining a party on Lake St. Clair. In the report of that two months, written by the director of the laboratory, Professor J. E. Reighard, are given in full the reasons which led to the inception of the undertaking and the aims which its promoters held in view. A study of the life of the lake in all its manifold interrelations and especially of those factors which bore upon the welfare of the food fishes in general and the young whitefish …

Science And Culture, Charles E. Bessey

Papers in Systematics and Biological Diversity

It is with peculiar pleasure that I stand before this new department of Natural Science Instruction, and I deem it a great honor that you have asked me to preside over its deliberations. It is an important sign of the times that such a department as this should have been organized by the scientific men of the country. It is significant of a broader view of the work of scientific men that we find so many here to-day to take part in the first meeting of a department which has for its object the discussion of questions pertaining to the …

The Classification Of Diatoms (Bacillariaceæ), Clarence Elmore

School of Biological Sciences: Faculty Publications

There have been many systems of classification employed for the Bacillariaceæ, but very few of these have any valid claim, to be regarded as natural systems. They may be divided into three classes (1) those based on the structure of the valves, of which Kuetzing's, Professor H. L. Smith's, and that employed by Kirchner are examples; (2) those based on the form of the frond, the connecting membrane, and the gelatinous envelope, represented by Reverend William Smith's; and (3) those based on the structure of the endochrome and the manner of forming auxospores, represented by that of Paul Petit. The …

The Plant-Geography Of Germany, Roscoe Pound

School of Biological Sciences: Faculty Publications

In a recently published address Dr. Coulter speaks of a new movement in botany which is sending botanists " to the great laboratory of nature," and replacing collecting trips by biological surveys. "The old-fashioned collection of plants," he says, "will hold no more relation to the new field work than the old geology, with its scattered collection of fossils, holds to the topographic geology of to-day." Geographical botany as it is now understood is comparatively a recent development. Collectors and cataloguers for a long time have been gathering a portion of the bare facts upon which geographical botany must proceed, …

Experiments in the culture of the sugar beet in Nebraska in 1894 and 1895.

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 …

Flora Of Nebraska: Part 21. Rosales, Per Axel Rydberg, The Botanical Seminar, University Of Nebraska

School of Biological Sciences: Faculty Publications

DeCandolle, the author of Calyciflorae, gives the following characters (Prodromus, 2: 1): “Calyx gamosepalous, that is, the sepals more or less united at the base. Torus more or less adnate to the bottom of. the calyx. Petals and stamens inserted on a torus which is partly adnate to the calyx, and therefore geuerally said to be borne on the calyx. Petals free or united with each other. Ovary free, or adnate to the calyx.”

What has generally been regarded as the lower portion of the gamosepalous calyx, and is described as such in many recent systematic works, is in reality …

The Earliest Name For Steller's Sea Cow And Dugong, Theodore S. Palmer

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In 1811, Illiger published a number of new genera, proposing among others, Rytina for the sea cow of Bering Island and Halicore for the dugong of the Indian Ocean. Nearly all recent writers on mammals have adopted these genera, apparently overlook ing the fact that both animals had been named before 1811. As early as 1794 Retzius described the sea cow in the 'Handlingar' of the Stockholm Academy of Science, placing it in a new genus which he called Hydrodamalis, and the species, based on the Vacca marina of Steller, Hydrodamalis stelleri. The generic description is sufficient to …
