Cape  aloes  in  appearance  more  than  chemical  contents.  Weigel 
also  gives  a  comparative  table  of  solubility,  ash  and  water  content 
of  Uganda  aloes,  compared  with  some  of  the  other  well-known  varie- 
ties.

Curacao  \  glossy 72*44  2-40  774 
L  hepatic  71*26  1/60  9*32 
This  table  brings  to  mind  a  statement  made  by  Holmes  and  Fuge 
at  the  British  Pharmaceutical  Conference,  Edinburgh,  1892:35  "  The 
sooner  the  exuded  juice  is  evaporated  after  collection,  the  larger  is 
the  proportion  of  water-soluble  matter." 
Uganda  aloes  does  not  appear  to  have  met  with  the  popular  and 
rapid  success  that  its  promoters  had  anticipated.  This  is  probably 
largely  due  to  the  fact  that  in  every  European  Pharmacopoeia  in 
which  Cape  aloes  is  official,  the  requirements  are  that  it  be  glossy 
and  vitreous.  This  is  particularly  true  of  the  German  Pharmaco- 
poeia, in  which  considerable  stress  is  laid  on  this  particular  physical 
property. 
According  to  Gehe  &  Co.,  it  is  probable  that  the  process  will  be 
so  modified  as  to  produce  a  variety  of  aloes  that  will  conform  more 
nearly  with  the  requirements  of  the  German  Pharmacopoeia. 
This  particular  variety  of  aloes  does  not  appear  to  have  reached 
the  American  market,  as  a  number  of  inquiries  sent  to  wholesale 
dealers  and  drug  brokers  failed  to  furnish  any  clue  to  even  a  speci- 
men sample  of  the  new  drug.  In  older  works  of  reference6"12  a  modi- 
fied or  better  quality  of  Cape  aloes  is  sometimes  referred  to  under 
the  name  "  Bethelsdorp"  aloes.  This  is  not  now  an  article  o~  com- 
merce, but  may  have  been  the  antecedent  of  Uganda  aloes. 
JAFFARABAD  ALOES. 
This  variety  of  aloes,  while  not  found  on  the  American  market, 
has  been  referred  to  by  several  European  writers  recently,  and  is 
particularly  interesting  in  connection  with  some  or  the  newer  work 
on  the  chemistry  of  aloes. 
According  to  Schneider  and  Suss25  this  Is  a  vitreous  variety  rom 
the  East  Indies.  It  appears  to  reach  the  Euro(  ean  markets  rrom 
Bombay.     Holmes,36  in  describing  this  variety  of  aloes,  says:
