tioBs is almost the same in the case of 

 glucose, fructose and mannose, but rather 

 less in the case of galactose. These results 

 are most easily brought into accord on the 

 assumption that the enzyme combines with 

 the sugar. 



Fermentation by yeast-juiee differs in 

 many respects from that by living yeast. 

 It is probable that the mechanism of the 

 reaction is the same in each ease; but the 

 relative rates of the different steps in the 

 two processes are different. The experi- 

 ments show that there is an essential step 

 in fermentation in which phosphates in 

 some form or another play a part.

SIXTEENTH INTERNATIONAL CONGRESS 

 OF AMERICANISTS 



The Sixteenth International Congress of 

 Americanists was held in Vienna from Sep- 

 temper 9 to 15. The congress was well at- 

 tended, particularly by students from 

 South America. Representatives were also 

 present from Russia, Sweden, Denmark, 

 Germany, England, Holland, Belgium, 

 France, Spain and Italy. The attendance 

 of ethnologists from the United States was 

 not as great as might have been desired. 



Owing to the presence of a considerable 

 number of South Americans, many of the 

 subjects discussed before the congress re- 

 lated to the archeology of that continent. 

 Mexican archeology was also well repre- 

 sented ; while the ethnology and archeology 

 of North America, which at the Fifteenth 

 Congress of Americanists played a par- 

 ticularly important part, was hardly dis- 

 cussed at all. Following is a list of the 

 papers read before the congress:
