Vines .— The Proteases of Plants ( VIJ) 
liquid is neutral or alkaline (e. g. o-6% Na 2 Co 3 ) than when it is acid 
(e. g. c-o6 % HC1): that is to say, the purified peptase behaves in such 
a way as to suggest that it is rather an endopeptase than an ectopeptase. 
The question as to its nature must therefore be left open for the present.
