Important Books in Science 



Morphology of Gymnosperins. By John M. Coulter, Professor of Botany, and Charles J. 



Chamberlain, Associate Professor of Botany, in the University of Chicago. 470 pages, 



462 illustrations, 8vo, cloth; postpaid, S4.22. 



Each of the seven great groups of gymnosperms is here presented in detail, and a final chapter 

 discusses the problem of phylogeny and points out tlie evolutionary tendencies. The extinct groups 

 are now included for the first time ; and vascular anatomy is recognized as a morphological subject of 

 first importance. The illustrations are numerous and in large part original. 



Nature. The bools; is an tinvaluable record, admirably illustrated, of our present knowledge of 

 the older type of seed-plants. 



Outlines of Geologic History With Especial Reference to North America. Symposium organ- 

 ized by Bailey Willis, of the United States Geological Survey ; compilation edited by 

 RoLLiN D. Salisbury, Professor of Geographic Geology in the University of Chicago. 316 

 pages, 8vo, cloth ; postpaid, 11.66. 



These essays and discussions embody the present state of knowledge and opinion concerning many 

 of the fundamental problems of North American geology. The value of the book is greatly enhanced by 

 the fifteen paleogeographic maps by Bailey Willis. 



Scottish Geographical Magazine. The value of such a collection is very great, as each writer dis- 

 cusses orJy the formation or subject which has formed his own special study. 



American Permian Vertebrates. By Samuel Wendell Williston, Professor of Paleontology in 

 the University of Chicago. 152 pages, 39 plates, Svo, cloth ; postpaid, S2.68. 

 This work comprises a series of monographic studies, with briefer notes and descriptions, of new 



or little-known amphibians and reptiles from the Pemiian deposits of Texas and New Mexico. The work 



is illustrated by the author. 



Athenaeum. The paleontologist will welcome the work as a solid contribution to our knowledge 



of a fauna which is of exceptional interest to the student of evolution, inasmuch as it includes forms 



that help to bridge over some of the differences between reptiles and amphibians.
