The Insect Galls Of Cedar Point And Vicinity, Paul B. Sears

Papers in Ecology

The following list is based on rather careful collections made during the summer of 1914. Since the list contains many forms common throughout Ohio, I have aimed to make the synonymy fairly complete to date, as an aid to students, while the bibliography has been limited to original description (where possible) and some more recent notice which should be helpful.

In the course of this work I have become deeply indebted to Mr. W. J. Kostir, of Ohio State University, while Prof. Herbert Osborn, Prof. B. W. Wells, Prof. Myron Swenk, Miss Edith Patch, Mr. Nathan Banks and others have …

A Revision Of The Cestode Family Proteocephalidae, George Roger La Rue

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Introduction

Several years ago while studying under Professor Henry B. Ward .at the University of Nebraska the writer began an investigation of a cestode parasitic in Amblystoma tigrinum (Green). That investigation resulted in a paper (La Rue 1909) in which a number of points in the anatomy of Proteocephalids were cleared up and certain problems were -outlined for investigation at an early date. In the meantime the writer became interested in the large number of Proteocephalids which Professor Ward had secured by work in the field and by exchange. The writer had also made some collections. A preliminary study of …

Problem Des Hummelstaates, Ludwig Armbruster

An

Die Honigbienen, dieses Paradigma der Biologie, geben trotz aller "Apistik" uns noch manche Rätsel auf. So wichtige Aufschlüsse wir für eine richtige Bewertung der Bienenbiologie aus einem eingehenderen Studium der Hummeln erwarten dürfen, so lückenhaft ist - freilich relativ gesprochen - andererseits das, was wir genaueres von deren Leben und Treiben wissen.

Citrus Talks-The Future Of The Orange Industry, Charles C. Chapman

Charles C. Chapman Citrus Speeches

This is a speech read before the State Horticultural Convention in Los Angeles. Mr. Chapman offered the following observations about the future of the orange industry--that cost saving methods must be employed in the labor of handling and marketing of the fruit in order to compete with foreign markets. He also predicted that scientific methods may not only assist in finer and more uniform crops, but also in finding ways to make use of the byproducts of the orange. Increasing the export market for the orange will increase revenues and the opeing of the Panama Canal should assist with exporting …

Dramatic Elements In American Indian Ceremonials, Virginia Shropshire Heath

Papers from the University Studies series (University of Nebraska)

"Poetry in general," says Aristotle, "seems to have sprung from two causes, each of them lying deep in our nature-first, the instinct of imitation ..., next, ... the instinct for 'harmony' and 'rhythm.'" Many of the lyric-legend-dance complexes of certain North American Indian religious ceremonials would seem to bear out this judgment. Indeed, in not a few of the unmistakably poetic expressions, there may be found well-defined dramatic elements suggesting the possibility of a developed, independent dramatic literature, had these savage peoples been left alone to initiate a civilization and culture of their own. The South American Indians were capable …

Experimental Ingestion By Man Of Cysticerci Of Carnivore Tapeworms, Maurice C. Hall

Harold W. Manter Laboratory: Library Materials

Excerpt:

Having experimentally eaten the larvae of dog tapeworms on two occasions, I undertook to look up the literature on this subject in connection with the ingestion of Cysticercus pisiformis to check the frequently quoted record of T. pisiformis from man. I find that there are more cases of the sort than I had supposed, so I have collected these cases in connection with a recent similar case of my own.

Taenia pisiformis, under the name of T. serrata, has been recorded as a parasite of man by Vital ( 1874), who records, in effect, two cases. One …

The Destruction Of The Vitality Of Cysticercus Bovis By Freezing, Brayton H. Ransom

Harold W. Manter Laboratory: Library Materials

First two paragraphs:

The question as to the length of time Cysticercus bovis may survive after the death of its host has been quite definitely settled by the researches of Perroncito, Zschocke, Ostertag and others. Perroncito (1877) found that the cysticerci in an artificially infested calf were all dead fourteen days after the slaughter of the animal. However, Zschocke (1896) succeeded in infesting the human subject with a tapeworm by feeding five cysticerci from beef kept from fourteen to sixteen days after slaughter. No infestation followed the swallowing of five cysticerci from beef kept twenty-one days after slaughter. Ostertag (1897) …

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings

Harold W. Manter Laboratory: Library Materials

Excerpt:

With the growing interest in pellagra, following the authoritative recognition of its presence in the United States in 1907, the study of its etiology was taken up by various investigators and the several theories of causation were subjected to close scrutiny.

Prominent among these theories was that of insect transmission, first advanced by Sambon, who limited this function to the species of blood-sucking gnats comprising the genus Simulium.

The importance of the disease and the possibility of such a factor in its causation, led the Bureau of Entomology, late in 1911, to undertake an investigation of the subject …

Variation In Oxyurias: Its Bearing On The Value Of A Nematode Formula, Stanley B. Fracker

Harold W. Manter Laboratory: Library Materials

Excerpt:

One of the most difficult problems in zoologic science is the classification of round worms. Authors and lecturers, after a carefully outlined and definitely arranged discussion of trematodes and cestodes, are compelled to consider nematodes in a somewhat desultory and inaccurate fashion. Two reasons for this may be given, the greater being the apparent lack of a basis for determining the phylogeny of the major groups, a condition with which we are not at present concerned. The other obstacle is the difficulty of differentiating between species and uncertainty as to the value of different kinds of taxonomic characters. The …

Observations On The Eggs Of Ascaris Lumbricoides, Winthrop D. Foster

Harold W. Manter Laboratory: Library Materials

First paragraph:

The appearance of the ova of Ascaris lumbricoides as seen in fresh feces is so well known to physicians and zoologists that description is unnecessary. Occasionally, however, ascarid eggs are found which differ so widely from the normal egg of Ascaris lumbricoides as to cause considerable confusion on the part of observers, and may even be so misleading in appearance as to be attributed to another species. One of these atypical forms, the unfertilized egg of Ascaris lumbricoides, first reported by Miura and Nishiuchi (1902), is by no means rare, and is usually seen in the feces …

Rhabditin, Nathan Augustus Cobb

Harold W. Manter Laboratory: Library Materials

Excerpt:

Rhabditin is the term applied by the writer to an organic substance, the type form of which is found crystallized in brilliantly doubly refractive spheres arranged in a definite way in the cells of the intestine. Rhabditis monhystera Bütschli, and other nematodes, in whose metabolism it plays an important role.

Rhabditin crystallizes under the life influences of Rhabditis monhystera into spheres, about 1 to 3 microns in diameter, which are rather slowly soluble in water, rapidly so in alkalies and acids—in the latter without effervescence—and are insoluble or but very slowly soluble in alcohol, glycerin, xylol and oils. The …

Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley

Harold W. Manter Laboratory: Library Materials

Excerpt:

The danger in using isolated sentences from an article as a basis for interpreting the author's theories, is generally recognized, but sometimes the most careful workers fall into the trap. Once the mistaken interpretation is published, it may be copied over and over again until it rises to the dignity of a dogma.

A striking illustration is afforded by the practical unanimity with which writers on the subject of insects and disease credit Dr. Josiah Nott with being the earliest to formulate definitely the theory of mosquito transmission of yellow fever.

Bulletin No. 135 - A Study In Annual Egg Production: Based On The Records Of A Flock Of Seven-Year-Old Hens And Their Progeny, E. D. Ball, Geo. Turpin, Byron Alder

UAES Bulletins

Experimental work in breeding for egg production was started with this flock of Single Comb White Leghorns in 1907. The flock of 1907 was hatched from eggs from a small flock that had been introduced into the plant two or three years before.

After two years' records of these flocks had been completed and studied it was found that nearly three-fourths of the first flock had made better records the second year than they did the first and that there was a great variation in the two years' records of individual hens. This raised the question of whether the first …

The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The profitable cultivation of the non-irrigable lands in west central and western Nebraska is limited by the amount and efficient use of the precipitation. There are tracts of land in the sand hills and minor tracts of badly worn heavier soils where the need of soil fertility is becoming evident. But, in the main, the great problem at present is not one of soil fertility, but of how to get enough water to make use of the fertility now present. The rainfall of this section, which varies from an actual shortage to seldom more than a meager sufficiency, makes it …
