interesting to see to what extent the difference in the results may be 

 correlated with a difference in temperatures. 



It may be seen from the data for these experiments that the molting 

 period for series A extended over the interval between July 8 and 

 July 22 ; while series B molted between the dates July 2 1 and August 

 8. In order to ascertain to what extent there was a difference in 

 the temperature for these two periods corresponding with the differ- 

 ences in molting, a comparison of the water temperature during these 

 periods is necessar3^ The following average temperature readings 

 of the water are taken from the Station records.*

 tAfter the closing of the lobster hatching season, the temperature readings at the station 

 were not taken every day, so it was not possible to get daily readings for the month of 

 August.
