soluble in hot water and alcohol; a resin acid, having an irri 
tating and bitter taste, insoluble in water and ether, soluble i 
alcohol and alkalies ; and a soft resin similar to that found i 
the fruit flesh of the female plant. ( Year-Book of Pharmacy, 1880, 
p- 212.) Dr. Sidney Martin (Journ. Physiol. V., 218—230, 
VI., 336—360 ; Journ. Chem. Soc. 1886, 641,) has shown pap 
to be a protolytic ferment, which acts very similarly to tryp 
Experiments performed with fibrin and white of egg show 
that some degree of digestion occurs when the liquid is faintl 
acid (0°05 per cent. of HCl); the presence of more ati 
than this hinders the action of the ferment. Digestion t 
place actively only in neutral or in alkaline solutions (0°25 
cent. of sodium carbonate) ; it occurs most readily ata ter 
perature between 35° and 40°C. ‘The results of digestion a 
peptones, leucine and tyrosine and an intermediate globul 
like substance, similar to that formed in pancreatic. digestion. 
In the author’s second paper on the same subject the fei 
ment in papaw juice is shown to be associated with an a 
mose, and to give the following reactions in addition to t 
previously described by Wurtz:—The solution gives a biur 
reaction, and it is precipitated from aneutral solution of sodi 
magnesium sulphate or sodium chloride alone, as globuli 
are, It is soluble in glycerol, and if precipitated from 
solution by alcohol, the filtrate has no proteolytic power. 
kind of albumose is one nearly akin to the protalbumose 
-Kuhne and Chittenden, and is called a-phytalbumose, Pa 
juice also contains a milk-curdling ferment. The prot 
present in papaw juice were found to be as follows :— 
(1) Globulin, resembling serum globulin in its most im 
tant properties. 
(2) Albumin. 
(3) 8-phytalbumose precipitated almost completely by 
by saturation with. neutral salts, but not by dialysis. 
differs from the heteroalbumose of Kiihne and Chittenden | 
not being precipitated by dialysis, by copper sulphate,
