Excerpt from Shorter Contributions to General Geology, 1918 I have been enabled to make the determina tions described in this paper through the inter est and cooperation of T. W. Vaughan, of the United States Geological Survey, and H. F. Moore, of the Bureau of Fisheries. Mr. Vaughan pointed out the need of such determinations, particularly for American waters, and Mr. Moore authorized the collection of the samples, which were actually collected by W. W. Welsh and shipped in citrate Of magnesium bottles to the chemical laboratory of the Geological Survey for analysis. It is a great pleasure to express appreciation for the assistance offered by all those who helped to make the study possible.
