found follicular glands, apparently similar to those in the small intestine, 

 and which furnish a secretion which it is claimed will turn starch into 

 sugar and albumen into peptone. The latter statement, which is made 

 by Thanhoffer, seems to need confirmation. It is, at any rate, clear that 

 the degree of digestion occurring in the large intestine must be slight, 

 since the greater part of the food-stufTs which reach the large intestine

 alimentary canal. In the large intestine in caruivora the contents of the

 condensed from the rapid absorption of water and other fluids which 

 takes place through its walls. In the solipedes the large intestine is par- 

 ticularly active as an absorbent, removing water and various fluids 

 secreted by the upper portions of the alimentary tube and the alimentary
