6. On the formation of urea - the ponenes of albuminous maiters.—~ 
Bécuamp has succceeded in showing that urea is one of the products of 
the oxydation of albuminous bilan The author effects the decomposi- 
tion by an alkaline solution of hypermanganate of potash. The fibrine 
of the blood and gluten yield also urea by the same process. From these

an alkaline influence yields pai very different from those obtained at
