ALIMENTARY CANAL IN THE BEE 



519 



Altogether thirty analyses were performed, a table relating 

 to the periods of which is adduced below. 



Total 



795 bees 



As the primary aim of the present work we regarded the 

 qualitative determination of the ferments in the different 

 portions of the ventriculo-intestinal tract of the bee, omitting, 

 meanwhile, the investigation of the ferments of their salivary 

 glands. 



In the intestine were established catalase, inulase, lactase, 

 invertase, lipase, pepsin, trypsin, chimosin, and emulsin. Of 

 these ferments we have investigated in fuller detail the catalase 

 and invertase.
