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

The type specimen of the genus Amebelodon is installed in the Nebraska State Museum, the University of Nebraska, Lincoln.

Morrill by Mr. Phillip Orr, April 4, 1927; was briefly described and figured in a Museum …


A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy May 1929

A Study Of The Oxidation Of D-Glucose With Air In A Saturated Solution Of Barium Hydroxide, Clyde Wilson Eddy

Open Access Master's Theses (through 2010)

The conversion of one aldose into another aldose and several ketoses slowly by weak alkalis at ordinary temperatures and quickly with much decomposition at elevated temperatures, was first observed by Lobry de Bruyn and later investigated by Nef and his students in an elaborate study on the action of strong alkalis alone and with oxidizing agents extending over a period of ten years. The results of these studies on oxidation were interpreted as depending on the presence of several intermediate enediols. The oxidation of sugars in approximately six normal alkali medium with air or oxidizing agents all give about the …

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

The group of proboscideans which we have called the shovel-tuskers or Amebelodonts, was announced in June, 1927,1 following the discovery of Amebelodon fricki. In the field season of 1928, two additional species were found which are represented by mandibular tusks. One of these is a tip of a large and unique tusk, numbered 2-3-9-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. It was found within 200 to 300 yards of the spot on his farm where Mr. A. S. Keith, Freedom, Frontier County, Nebraska, found …
