Xo explanation of the above experiments is here attempted, but attention is 

 briefly called to the following negative points : — 



Osmosis, filtration into the blood capillaries, or into the lacteals bythe action of 

 Briicke's ' villus pump ' are, it is considered, excluded by the conditions of the 

 experiment. 



That the disappearance of the serum from the cavity of the gut is simply a
