one remains to function in each oosphere. Trowis convinced that true fertil- 
ization, a fusion of sexual nuclei, does occur. It is to be regretted, however, 
that his technique was not improved to such a point of efficiency as to insure 
more unequivocal evidence than he presents. The final impression that is 
left with the critical reader is that Trow has seen some things which make a 
fertilization seem possible, or even probable; but that it is far from being 
proved. A really valuable feature of Trow’s work consists in the observa- 
tions on live material, by which he has followed the growth of the organism 
from the zoospore to complete maturity, including oC ripening, and 
germination of the oospores. 
An article which bristles with caustic but mainly petty criticism regarding 
Trow’s conclusions and theories appears in the September Anmads of Botany. 
This criticism, like Hartog’s criticism of Trow’s earlier paper, while it 
increases the literature by several pages, sheds no light on the perplexing 
questions.— F, L. STEVENS.
