Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This paper must not be mistaken for a report on the fossils of Nebraska. It is merely a circular letter to correspondents describing and figuring those fossils only which occasion frequent comment. In two recent papers of the Survey consideration was given to the common minerals and rocks of Nebraska, and it seems opportune to briefly discuss our fossils in a like manner. Probably no other State can boast of such a well-preserved and varied fauna.

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska¹. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.

Nebraska Minerals Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

The Minerals, Rocks, and Fossils of Nebraska, which Excite Common Inquiry, are treated brefly in leaflets numbered 37, 37a, 37b, respectively. These are intended to serve as circular letters to correspondents. Possibly they may prove to be acceptable and helpful in a measure to teachers and others who conduct parties of school children on field excursions.

The Round Ligament Of Nebraska Proboscideans, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

Comparisons of the acetabula of various mastodons and mammoths common to Nebraska show conclusively that absence of the round ligament is not a characteristic of the proboscidea, as generally accepted. From the specimens in our collections, there is evidence that the ligament was not on! y present, but was uncommonly large and well developed in the earlier Nebraska proboscideans. Examination of material collected since 1891, and preserved in the cabinets of the Nebraska State Museum. and the Morrill Geological Collections, makes it apparent that all Nebraska proboscideans had round ligaments, though perhaps the latest survivors did not.

A New Saber-Toothed Cat From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division: Faculty and Staff Publications

During the field season of 1913, while exploring the Pliocene beds of Brown County, Mr. A. C. Whitford, a Fellow in the Department of Geology, University of Nebraska, discovered the mandible of a new machaerodont cat. His work in this region was in the interest of the Nebraska Geological Survey and the Morrill Geological Expeditions.¹

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 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 …

A Phenomenon Of The Kansan Drift In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Among the minor phenomena of the glacial drift in Nebraska there is one which, though rarely observed by the public, is of interest and should be commended to the attention of naturalists. The reference here is to certain large, well-defined masses or blocks of such materials as sand, gravel, and coarse pebbles, which occur imbedded in the drift clays along with glacial bowlders, and which presumably have been similarly transported and deposited. These masses or blocks vary widely in color, texture, and kind. They also vary from the glacial matrix in which they are found and are the more striking …

Dramatic Elements In American Indian Ceremonials, Virginia Shropshire Heath

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

"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 …

Charles Peirce At Johns Hopkins, Ellery W. Davis

Mid-West Quarterly (1913–1918)

In the company of scholars and investigators which Daniel Coit Gilman gathered at Baltimore in the seventies and eighties was Charles S. S. Peirce, son of the Harvard mathematician, Benjamin Peirce, and considered by Sylvester (surely a capable judge) “a far greater mathematician than his father.” But great though his mathematical powers were, it is not they alone which chiefly distinguished him among the scientists of his generation. Mathematics was simply one of the many fields of thought tilled by his active brain. At Harvard it was in chemistry that he had chiefly distinguished himself, but it might as well …

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

Harold W. Manter Laboratory of Parasitology: 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 of Parasitology: 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 of Parasitology: 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 of Parasitology: 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 …

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

Harold W. Manter Laboratory of Parasitology: 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.

Nuttall, in his classic monograph On the Role …

Rhabditin, Nathan Augustus Cobb

Harold W. Manter Laboratory of Parasitology: 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 …

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

Harold W. Manter Laboratory of Parasitology: 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 Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

On The Sedges Of Nebraska (Family Cyperaceae), John Mallory Bates

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

The sedges (Family Cyperaceae) are grass-like plants, but easily distinguished from the true grasses (Poaceae) by the following characteristics: culms solid, pithy, cylindrical, trigonous or flattened. Grass culms by contrast are mostly hollow and cylindrical. Sheaths not open lengthwise opposite the leaf blade, tightly enclosing the culm. Spikes simple or compound, mostly subtended by leaflike bracts, which are sometimes longer than the culm. Spikelets one- to many-flowered, each flower subtended and sometimes embraced by a single short herbaceous or scarious bract or scale, the most characteristic mark of this family. Fruit an achene, trigonous, lenticular, or plano-convex; …

Iv. On A New Fossil Fungus From The Nebraska Pliocene, A. C. Whitford

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

While studying the fossil woods of Nebraska, under the direction of Dr. E. H. Barbour, it was my good fortune to find an interesting specimen. This specimen is in the collection of fossil woods in the Nebraska State Museum, and was collected by Dr. Barbour from the Pliocene, or Snake Creek beds, about 20 miles south of Agate, Nebraska, during the summer of 1911.
The specimen itself is about six inches long by four inches wide and two inches thick. It has the appearance of typical agatized wood, but has numerous limonite streaks running through it. Upon sectioning the specimen, …

I. On The Distribution And Composition Of The Humus Of The Loess Soils Of The Transition Region, Morris Blish

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

The main object of this investigation has been to determine the distribution of the humus, to a depth of six feet, throughout the soils in representative virgin prairies of the so-called “transition region" of Nebraska. This region is the large area which extends westward from the Missouri River for a distance of over three hundred miles and which is covered, for the most part, with loess soil. This is, agriculturally, the most important soil in the state of Nebraska, and covers more than half the area of the state. The term "transition region" is employed to convey the idea of …
