EXP. 3. TEMPERATURE ESTIMATED 15-16 C. 



a. Membranes generally excentric, many partial. 



b. All have fine membranes (optimum). 



c. All have membranes, generally good, some excentric. 

 In a all membranes destroyed ; eggs agglutinated. 



In b 70 per cent, membranes destroyed ; much agglutination. 

 In c 50 per cent, membranes destroyed; much agglutination. 



EXP. 7.1 TEMPERATURE 15 C. 



i This experiment was run in two sections, a-e and f-o. The exposure 

 times y, e and / were thus repeated. 



EXP. 8. TEMPERATURE 17 C. 



All of a, b and c formed membranes.
