752 SCIENTIFIC RECORD FOR 1885. 



Ward, L. F. — Fontaine's Older Mesozoic Flora of Virginia. Science, 

 vol. V, No. 113, pp. 280, 281. April, 1885. Cambridge. 



A review of " Contributions to the Knowledge of the pider Mes- 

 ozoic Flora of Virginia, by William Morris Fontaine. Washington, 

 1883. 12-144 pp., 54 pis. Monographs of tbe U. S. Geological Survey, 

 No. VI." The reviewer, while differing slightly from Mr. Fontaine's 

 analysis of the facts, agrees with him in correlating the Richmond 

 coal-fields with the Khaetic of Europe. The reviewer further states 

 that the '^ seven Jurassic species are mostly from the Lias, or Lower 

 Oolite, which, while not negativing the Ehsetic character of the Vir- 

 ginia beds, does seem, when coupled with the rest of the evidence, 

 to negative their Triassic character." From this remark it would seem 

 that the reviewer considers the Rhaetic as of Jurassic rather than Tri- 

 assic age, a conclusion he is hardly justified in assuming.

 presideutal address delivered at the fifth anniversary meeting of the 

 Biological Society of Washington, January 24, 1885. Proc. Biol. Soc.

Concludes that the field geologist and paheontologist must work in 

 concert. Indeed, the field geologist who ignores the use of fossils, as 

 some have affected to do, is sure to burden science with the results of 

 worthless work, and the palaeontologist who does not goto the field and 

 study there the formations from which his fossils have been obtained is 

 sure to produce results of work which will be worthy of the condemna- 

 tion of both geologists and biologists. 



White, C. A. — Notes on the Jurassic Strata of North America. Amer. 

 Journ. Sci., 3d ser., vol. xxix, pp. 228-232. March, 1885. New Ha- 

 ven. 



A criticism of Mr. J. F. Whiteaves's views as expressed in "Mesozoic 

 Fossils, vol. I, part iii, Geol Survey, Canada, 1884." The author criti- 

 cises the identification of nine species of fossils from the Cretaceous strata 

 of British Columbia with fossils considered Jurassic in the United 

 States, and considers the identity of the beds containing them as in no 

 measure j)roved.
