The distribution of botulinus toxin in duck sickness areas The distribution of botulinus toxin in duck sickness areas
One of the most important events in the history of the diseases of wildfowl wa the discovery of the cause of western duck sickness. Determination that this malady of migratory birds is not a chemical poisoning, as had been previously suspected, was made by Kalmbach and others in 1930-31.

Means of recognizing source beds Means of recognizing source beds
Eight characteristics of sediments are considered as possible means of recognizing source beds: 1, quantity of organic matter in the sediments; 2, reducing power, which is a measure of ability of the sediments to reduce chromic acid; 3, color of sediments; 4, volatility of sediments; 5, degree of volatility, which is a measure of the volatility with respect to the organic content; 6...

Degree of reduction of sediments in the East Texas basin as an index of source beds Degree of reduction of sediments in the East Texas basin as an index of source beds
The research project on source beds, sponsored jointly by the U. S. Geological Survey and the American Petroleum Institute, for the past 18 months has undertaken a study of the degree of reduction as an index of source beds. As indicated in a previous paper on this same subject presented before the Institute at the Los Angeles meeting, this index has to be tested in several petroliferous...
