a decrease in lipoid phosphorus, as will be described in the following 

 section, so that it seemed as if the amount of fatty acids in triglyceride 

 form must even rise rather than fall. Parnas & Krasinska did not 

 pursue their investigations into the free-swimming larval stage. The 

 work of Faure-Fremiet & Dragoiu paralleled that of Parnas &

Krasinska, in that only the pre-natal period was considered, but it 

 led to diametrically opposite results for they found a diminution in 

 total fatty acids amounting to 0-113 mgm. per embryo. Two other 

 researches, however, followed the development up to the end of the 

 yolk-sac. Bialascewicz & Mincovna measured the fatty acids at the 

 end of each period, and for the first of the two they confirmed Parnas 

 & Krasinska, observing no change, or even an increase, in the fatty
