Professor Dean reported progress upon several lines of re- 

 search. A paper dealing with Japanese oyster-culture had 

 been prepared for the government, and experiments upon in- 

 duced fossilization by means of calcium phosphate had been 

 pursued. The embryology of CJiiincBra had received special 

 attention, a conclusion of particular interest being that the 

 breaking up of the extra -embryonic yolk is due to supernu- 

 merary sperm-nuclei.
