The  precipitate  thus  obtained,  freed  from  salts  by  dialysis,  will  con- 
sist of  albumose  and  globulin,  and  the  weight  of  these  when  dried 
will  give  the  measure  of  soluble  bodies  with  which  the  ferment  is 
associated,  or  the  amount  of  ferment-bearing  bodies  in  the  sample. 
In  the  best  of  the  market  preparations  which  I  have  examined  I 
have  found,  in  addition  to  these  soluble  bodies,  insoluble  globulins 
and  an  appreciable  amount  of  peptone,  the  latter  not  being  precipi- 
tated by  the  foregoing  methods. 
Carica  Papaya,  split  open  to  show  sections  in  centre  of  trunk. 
DIGESTIVE  ACTION. 
The  digestive  action  of  the  ferment  of  the  papaw  plant  has  been 
quite  fully  described.  The  actions  which  are  here  summarized 
have  been  made  with  one  of  the  market  ferments  sold  under  the 
name  of  "  Papoid."19 
19  This  preparation  was  used  on  account  of  its  convenience  and  because  of  the 
lack  of  sufficient  material,  separated  by  the  processes  outlined  in  another  part 
of  this  paper.
