I. SMITHSONIAN CONTRIBUTIONS TO KNOWLEDGE. 



In the series of Smithsonian Contributions to Knowledge, three memoirs, 

 which were in press at the close of the last fiscal year, have been published.

 sonian Expedition of 1904. By William Hittell Sherzer, Ph. D. Quarto. 

 Pages xii, 135, with 42 plates. Part of Volume XXXIV. 



In this memoir Doctor Sherzer discusses the indicated physiographic changes 

 in the region during the Mesozoic and Pleistocene periods; the question of 

 precipitation of snow and rain, and the effect of climatic cycles on glacial 

 movements; the structure of the ice as to stratification, shearing, blue bauds, 

 ice dykes, glacial granules, and the possible methods of their development ; the 

 theories of glacial motion as applied to these glaciers; and the cause of the 

 richness and variety of coloring of glaciers and glacial lakes.

 Quarto. Pages 79, with 10 plates. I*art of Volume XXXV. 



In this memoir there Is described and illustrated the young of two kinds of 

 crayfishes, one from Oregon and one from Maryland, representing the two most 

 diverse forms in North America. The first, second, and third larval stages are 

 determined, and there is described the hitherto unknown nature of successive 

 mechanical attachments of the offspring to the parent.

 the work, a reprint of Mr. Langley's memoir on " The Internal Work of the 

 Wind," originally published in 1893 in quarto form as No. 884, Smithsonian 

 Contributions to Knowledge. To the present edition was added as an appendix 

 a translation of the " Solution of a Special Case of the General Problem," by

 Vent" in Revue de TAeronautique Theorique et Applique, Paris, pages 5S-GS.
