Stratigraphy of the outcropping formations in southern Florida
The geology of southern Florida, except for the Pliocene deposits, is not widely known among geologists and paleontologists. The popular concept is that there are very few outcrops in this part of the State. It is true that there are very few natural exposures, but the dredging of rivers and the construction of canals have made many exposures. The Tamiami formation is the only formation of Miocene

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. Thtat it is a food poisoning resulting from toxins produced by botulinus organisms was proved beyond question.

Disease relationship of domestic stock and wildlife
From the time that western civilization established itself on the North American continent until very recent years, little thought was given to the diseases, or other forms of loss, in game. In the process of bringing civilization and the incidental domestic arts and trades to the United States it appears to have been the policy to establish domestic farm stock on the land just as abundantly as th

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, ratio of carb

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 provinces
