which  mostly  reach  the  markets  of  this  country :  Tellicherry,  Singa- 
pore, Aleppi,  Acheen,  and  Lampong.  Hartel  and  Will5  have 
recently  made  complete  analyses  of  these  and  other  commercial 
varieties,  and  according  to  their  results  Tellicherry  and  Singapore 
pepper  constitute  the  better  grades  of  pepper. 
Hartwich6  was  one  of  the  first  to  show  that  the  heavier  the  pepper 
corns  the  greater  the  value  of  the  particular  variety  of  pepper  ;  and 
analysts  are  beginning  to  take  cognizance  of  the  comparative 
weights,  the  method  being  to  determine  the  weight  of  1 00  pepper 
corns.    The  following  figures  show  the  weights  of  ioo  peppercorns

of  several  commercial  varieties  determined  by  the  authors :  Acheen, 
4-452  grammes;  Aleppi,  3-673  grammes;  Lampong,  2-838  grammes; 
Singapore,  (a)  3-935  grammes;  (b)  4-013  grammes;  Tellicherry* 
4-412  grammes;  Bengal,  3-527  grammes;  unknown  pepper  corn, 
4-272  grammes.  These  figures  accord  rather  well  with  the  figures 
obtained  by  Hartel  and  Will.5  It  should  be  said,  however,  that  the 
specific  gravity  of  the  pepper  corns  would  probably  furnish  a  more 
reliable  indication  of  quality,  for  the  reason  that  the  pepper  corns 
vary  in  size,  those  of  Lampong  pepper  being  uniformly  small. 
For  example,  while  100  pepper  corns  of  Acheen,  Singapore  and
