may expect an even number, tliat is, either 46 

 or 48. 



My material to date includes the testes of 

 one white man and of two negroes. All indi- 

 viduals were castrated because of self abuse, 

 at one of the Texas state institutions. The 

 testes were removed with the use of local 

 anaesthetics and immediately preserved in 

 Bouin's fluid, to which chi'omic acid and urea 

 had been added. In less than a minute after 

 removal from the body the germ-cells were 

 being bathed in the fixing fluid. The preser- 

 vation thus obtained is very satisfactory. 



In view*of the uncertainty which has ex- 

 isted r^arding the chromosome number in 

 man, the author vnll gladly send samples of 

 this human material to any experienced 

 cytologist in order that the latter may verify 

 for himself the correctness of the chromosome 

 counts given. The complete spermatogenesis 

 of man is being reworked by the writer at the 

 present time and his results will be published 

 in the near future.

"The measurement of color," by C. E. K. 

 Mees. 



"Blue eyes and blue feathers," by W. D. 

 Bancroft. 



"Surface Films as Plastic Solids," by E. E. 

 Wilson. 



"The relation between the stability and the 

 structure of molecules," by Irving Langmuir. 



' ' Ionization of electrolytes, " by G. N. Lewis. 



The following divisions and sections met: 

 Divisions of Agricultural and Food Chemis- 

 try, Biological Chemistry, Chemistry of Me- 

 dicinal Products, Dye Chemistry, Industrial 

 and Engineering Chemistry, Organic Chem- 

 istry, Physical and Inorganic Chemistry, Rub- 

 ber Chemistry, and Water, Sewage and Sani- 

 tation; Sections of Cellulose Chemistry, Pe- 

 troleum Chemistry and Sugar Chemistry and 

 Technology. Further details of their meetings

 of Industrial and Engineering Chemistry. 



Tuesday evening was given up to dinners 

 and gatherings of various colleges and frater- 

 nities. On Thursday evening the good fellow-

 Society and consisted of 280 papers.
