A 'inliiiL; to the views of some observers it is said to be. pos- 

 sible to eli'eet a partial reconversion of peptones into the more 

 primary proteids from which they were obtained, hy nn-.i:

It was at one time stated that when peptone- an- injected into 



the hl..od-Ves.-els, the blood speedily loses its j.oWel of I'lottillg 



i.-moval from the body.' 1 This action is now known to be 

 due to the albumo-e- with which tlie i>ei>tones wen- nijxed.''' TM
