A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert

Bulletin of the University of Nebraska State Museum (1924–2023)

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …

The Effect Of Time, Temperature, And Pressure On The Hydrogenation Of Castor Oil, Anthony Toth

Bachelors’ Theses

The intention of the author in doing this research was to obtain some data on the effect of time, temperature, and pressure on the hydrogenation of castor oil at 100°C. The author is also interested to see if a method could be devised by which the saturated and unsaturated fatty acids could be separated from the hydroxy acids of hydrogenated castor oil.

The Effect Of Alcohols On Paramecia, William C. Lawler

Bachelors’ Theses

A phenomenon of surpassing biological interest is the adjustment of living substance to its surroundings. That living things should so act as to promote their own welfare is indeed wonderful; that such acts are common is evident on every hand.

Fermentation Of Sugar Acids By Bacteria, Gordon B. Robbins, Keith H. Lewis

Department of Chemistry: Faculty Publications

Bacterial fermentation of the sugar acids has received little attention in comparison with the wide-spread use of the common aldoses and sugar alcohols. These acids, and especially their sodium salts, are well suited to bacteriological techniques because of their solubility and heat stability, yet their usefulness for investigating the relationship of chemical structure to biological utilization has only recently been recognized. Their application to systematic differentiation of bacteria has also been neglected.

Kendall, Bly and Haner (1923) concluded from a study of three monocarboxylic acids and three dicarboxylic acids that these compounds possessed little value for the differentiation of bacterial …

A Comparative Study Of The Proteolytic Activity Of Trypsin On Various Gelatins, Louis Hinkle Coggs

Bachelors’ Theses

Since 1839, the viscosity of liquids has been measured by means of capillary tubes. However, it was not until the year 1846, that the results of Poiaeu1lle's research were :made known to the public. Because of the comprehensiveness of Poiseuille's work, the concept of the laws controlling viscometry flow is attributed to him. For one hundred rears the subject of viscometry has been studied by many. During these years the principle a propounded by Poiseuille have been verified in general, but various corrections and modifications of viscometers in regard to drainage, surface tension, liquid head, and kinetic energy have been …

Electrolytic Preparation Of Glucuronic Acid From Glucose, Thomas Mcguine

Bachelors’ Theses

The present work was undertaken to check the results of Dr. R.A. Leutgoeb in the electrolytic preparation and also to further the separation of glucuronic acid from the electrolyte.

Because up to 1938 no efficient chemical method of glucuronic acid had been developed. Dr. Leutgoeb undertook to remedy this lack by making use of electrolysis for a preparation from alpha methyl-glucoside. Such a chemical method is needed if biochemists wish to successfully continue work on the metabolism and deoxioating functions of glucuronic acid. Biological means indeed produce glucuronic acid but in low yields and after much time and labor. Hence …

The Comparative Ability Of The Bob-White And The Ring-Necked Pheasant To Withstand Cold And Hunger, Paul L. Errington

Other Publications in Wildlife Management

The native Bob-white (Colinus virginianus) and the introduced Ring-necked Pheasant (Phasianus colchicus torquatus) may both, on occasion, suffer severe winter mortality over much of their common range in north-central United States. Their habitats often overlap, although the Pheasant has a greater cruising radius and an ability to live in a more open type of country than the Bob-white. In given localities they also live upon much the same kinds of winter foods.

The scope of this paper is not intended to cover the ecological adjustments of Pheasants or of Bob-whites to their winter environment so much …

Bulletin of the University of Nebraska State Museum (1924–2023)

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936.

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum (1924–2023)

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.
