The use of soils and paleosols for interpreting geomorphic and climatic history of arid regions The use of soils and paleosols for interpreting geomorphic and climatic history of arid regions
The study of modern surface soils, and ancient weathering zones, which occur either buried or as surface relicts, has contributed materially to understanding the complex events of the glacial and post-glacial period both in glaciated areas and in regions not influenced by glaciation. Most work of this kind in the United States has been done by geologists.Numerous Pleistocene geologists...

Stratigraphy of the outcropping formations in southern Florida 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...

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