atazoid enters the egg cell swimming in between the rup- 
tured neck cells.” Only one spermatazoid is used in fe- 
cundation although two or three may enter the same egg. 
Fecundation consists of a fusion of two or more entire 
cells, cytoplasm with cytoplasm and nucleus with nucleus. 
MICROSCOPICAL SOCIETIES. 
PosTaL MicroscoPicAL SociETy.—The Annual Report 
for the season 1900-1901 records an improvement on the 
previous year, not only from the financial point of view 
but in other details. The number of boxes sent out has 
been considerably increased, and the Hon. Secretary has 
felt justified in purchasing a fresh stock of slides for use 
of the fociety, in addition to those contributed by the 
members themselves. The rules of the society have been 
modified in some details. The membership shows a slight 
increase, but we hope to see this improved upon in the 
forthcoming year... There are few amateur microscopists 
who would not find membership in this Society both help- 
ful and stimulating. They would have the opportunity 
of examining a large number of slides partly professional, 
but mostly mounted by workers in the same plane as 
themselves. The selected notes which appear each month 
in Science-Gossip will show of what nature are the re- 
marks and explanations accompanying such slides, and 
the subscription is only $1.25 per annum, with an en- 
trance fee of 60 cents. The Society needs money less 
than the help and interest of those who are themselves 
interested in microscopy, especially of those who are in- 
terested in research of any kind, however humble. The 
Hon. Secretary is Miss Florence Phillips, Hafod Euryn, 
Colwyn Bay, North Wales. |
