Bulletin No. 479 (191 1) is by ]Mr. Chase Palmer on the Geochemical 

 Interpretation of Water Analyses, and it is pointed out "that the 

 statement of water analyses in a form which does not recognize the 

 proportional reaction capacity of the radicles fails to show the chemical 

 character of the waters ". 



Bulletins Nos. 454 and 456 (1911) contain accounts of the Coal, 

 Oil, and Gas of the Foxburg Quadrangle, and of the Oil and Gas 

 Fields of the Carnegie Quadrangle, Pennsylvania. 



Bulletin No. 475 (1911), by Messrs. J. E. Gilpin and 0. E. Bransky, 

 gives the results of experiments on the diffusion of Crude Petroleum 

 through P'uller's Earth. It is found that the earth tends to retain 

 the unsaturated hydrocarbons and sulphur compounds in petroleum, 

 and very probably it retains largel)^ the nitrogen compounds in 

 the oil.

Ende 1910. Zusammengestellt von Dr. Karl Bedtler, 

 Paliiontologe in Miinchen. (Privately printed and sold by the 

 author, price 3s., and postage 3c?.) 8vo ; pp. 144. 

 ryiHIS is a useful compilation from Woodward, Sherborn, and 

 I Tutkovski, Avith much additional matter, tlirown into an 

 alphabetical list and divided up in the last few pages into Geological, 

 Morphological, Systematic, Bibliographical, Geographical Distribution, 

 Catalogues, and other headings, referring the reader by numerals back 

 to the author list of papers. It apparently takes little or no notice 

 of bibliogruphical details, and omits those painfully brought together 

 by Sherborn, as well as all pagination of the works quoted from. It 

 is also inaccurate in many particulars, notably in the omission of 

 Lister's valuable contribution to the Zoology edited by Lankester, 

 and of any reference to the first edition of Fichtel & Moll, etc. 

 Further, the entry of an author's name as Cuvier, Fichtel, Diesing, 

 Cross, Flint, Schroeter, and so on, is misleading, and only causes 

 confusion. In all works of this nature the full names of the authors 

 are essential, and in most cases easily ascertainable. 



The book will be serviceable, however, if carefully used, and we 

 thank Dr. Beutler for ])utting it together. 



VI. — Brief Notices. 

 1. Thermal Waters in the Yellowstone National Park. — The 

 origin of these waters is discussed by Mr. Arnold Hague {Science, 

 N^.s., xxxiii, p. 553, 1911). who maintains that they are not primitive 

 in their origin, but are due to vadose or surface waters that have 

 penetrated to a sufficient depth to attain a temperature that would 

 force them again to the snrface in the form of boiling springs and 

 aqueous vapours. This conclusion is based on the nature and structure 

 of tlie rocks through which the heated waters reach the surface, on 

 the mineral constituents of the waters, and those in the sediments and 

 incrustations deposited around springs and pools, and on the com- 

 position of the gases.
