(4) a«-phytalbumose; solublo in cold or boiling water; 
‘not precipitated by saturation with neutral salts, except in an 
acid solution. This is the vegetable peptone referred to by. 
ines (Journ. Physiol. ii.) as hemialbumose. It differs from 
-pitation by sodium chloride er by copper sulphate. Both these 
albumoses give the biuret reaction. 
No peptones occur in the juice, but leucine and tyrosine are 
_ present. By a series of digestion experiments carried out 
_on each of these proteids by papain in a neutral liquid, it was 
found that both the globulin and albumen are changed into 
‘@-phytalbumose, and that this becomes a peptone-like sub- 
stance, and forms leucine and tyrosine. The a-phytalbumose 
becomes a similar peptone-like substance, leucine and tyrosine 
q being formed. This peptone-like substance resembles the 
ld euteroalbumose of Kiihne and Chittenden, except that a 
solution of it, when rendered acid by acetic acid in the pre- 
~ of sodium chloride, dees not become cloudy on warming, 
No true peptones are formed. Probably digestion in the plant 
itself is very slow, as much more liquid was used in the experi- 
mts than is present in the juice. The albumose forms — 
bably the circulating proteid in the plant, (Year-Book of — 
Pharm., 1886, p. 97).
