January,  190S.  / 
Examination  of  Black  Pepper. 
7 
years  in  the  annual  reports  of  the  Connecticut  Agricultural  Experi- 
ment Station  furnish  the  best  record  of  the  work  thus  far  done  in 
this  country.  The  only  deviation  from  the  methods  of  the  A.  O. 
A.  C.  made  by  the  writers  was  in  the  determination  of  starch,  where 
Allihn's  original  method  for  the  determination  of  dextrose  was  fol- 
lowed in  pursuance  of  a  criticism  by  Winton. 
The  following  data  were  obtained  in  the  examination  of  six 
samples  of  Lampong  pepper : 
Crude  Fiber. 
Total  Ash. 
Ash  insoluble  in 
10  per  cent. 
Hydrochloric  Acid.
