relation is an important one, and that, during 

 normal ripening, an enzymatic agent is at 

 work effecting the coagulation. If this be 

 true, the role of carbon dioxid may be less 

 direct than above indicated, and that its busi- 

 ness lies in hastening the secretion or the ac- 

 tivity of the responsible enzyme.

FUNDULUS AND FRESH WATER 



In a series of papers^ published in 1906 and 

 1907, I presented the results of experiments 

 in which fishes of a number of species (par- 

 ticularly Fundulus heteroclUus) had been sub- 

 jected to various modifications of the salt con- 

 tent of the containing water and to various 

 other abnormal conditions. Contrary to the 

 previously published statements of Loeb" and 

 of Garrey," I found that in the great majority

 not intended offensively, I now recognize to have 

 been in poor taste.
