Comparative Weights of the Pancreas of Frugivorous and Granivorous Mammals. 



By comparing these numbers, we arrive at the following conclusions : — 

 1. The pancreas of the Garfish [Lepisosteus osseus), a powerful, voracious and 

 active fish, is much larger than that of more sluggish species. The Garfish con-
