SECTIONAL TRANSACTIONS.— H, I. 373 



In its lack of speciab'sation Papio Africanus conforms to a type such as would 

 be anticipated in an ancestral form, and it appears likely that Papio porcarius is a 

 descendant of this fosail species.

(e) Mr. T. Schrire. — Autogamy in Bacteria. 



The question of variation in bacilli was discussed. Mention was made of various 

 types of colonies met with in one organism. It was suggested that the variations in 

 these organisms' characters may be governed by some Mendehan law. The characters 

 of the colonies were described. 



Wednesday, July 24. 



Messrs. L. Mirvish, G. Sachs, and T. Schrire.- — Studies in the 

 Mechanism of Bile Secretion. 



Experiments have been done on the Calcium content of gall-bladder bile, as well as 

 bile draining from the common bile duct with the cystic duct tied. The results appear 

 to indicate that Calcium is excreted by the liver through the hepatic bile in quite 

 appreciable quantities, and that there are indications that Calcium is, to a certain 

 extent, selectively re-absorbed in the gaU-bladder. 



SimOar work on cholesterol is being undertaken.
