It is unusually complete and thorough in bib- 

 liographic detail. No one interested in the 

 development of stereochemistry can afford to 

 be unfamiliar with it, and to all scientific men 

 it must be of interest as an evidence of the 

 extraordinary fruitfulness during the last ten 

 years of an imaginative hypothesis.

 editing and publishing of the Journal of 



SOCIETIES AND ACADEMIES. 



THE CHEMICAL SOCIETY OP WASHINGTON. 



The 153d regular meeting was called to order 

 by the president at 8:10 o'clock, Thursday 

 evening, December 8, 1904. There were forty 

 persons in attendance. The program for the 

 evening consisted of the following three 

 papers : 



' Some American Contributions to Tech- 

 nical Chemistry.' Dr, Marcus Benjamin. 

 In this paper Doctor Benjamin presented a 

 summary of the principal advances made in 

 chemistry applied to the arts in this country 

 from the coming of Priestley in 1774 to the 

 present time, beginning with the description 

 of Count Rumford's work and including the 

 oxyhydrogen blow-pipe by Robert Hare, the 

 vulcanization of sulphur by Charles Good- 

 year, the processes invented by Castner as well 

 as many others. 



This paper has adequate footnotes, giving 

 references to biographical sketches of those 

 who had died, and exact reference to papers 

 discussing the invention while the inventor 

 was still living. 



The second paper, entitled ' Association of 

 Boron and Nitrogen in Nature,' was presented 

 by Professor F. W. Clarke. Numerous in- 

 stances were cited to show that wherever boron 

 occurs in volcanic water, compounds of am- 

 monium are also found. The most plausible 

 hypothesis to account for this occurrence is 

 that of Warington, which is based upon the 

 assumption that boron nitrite (BN) exists at 

 great depths in the earth and is acted upon 

 by volcanic waters. In southern California 

 and in Chili the borates occur associated with 

 sodium nitrate, and it was suggested that 

 these deposits, which are lake deposits, may 

 have derived their boron and nitrogen from 

 hot springs which are common in those re- 

 gions. The borates at Stassfurt are undoubt-
