/Am.  Jour.  Pharm. 
(.  December,  1901. 
This  work  was  written  with  the  special  object  of  facilitating  the 
study  of  the  native  medicinal  plants  by  the  numerous  medical  offi- 
cers stationed  at  small  posts  throughout  the  Philippines.  The  author 
has  given  the  common  names,  botanical  origin,  botanical  descrip 
tion,  habitat,  constituents  and  uses  of  the  drugs  considered  in  the 
book.  A  very  large  number  of  the  plants'enumerated  are  employed 
in  medicine  throughout  the  civilized  world.  A  number  of  the 
other  plants  have  been  known  to  be  used  in  India,  the  East  Indies, 
and  other  tropical  countries.  The  plants  mentioned,  which  are  pecu- 
liarly indigenous  to  the  Philippines  and  which  may  prove  of  value  in 
medicine,  are  relatively  few,  if  any.  The  work,  at  any  rate,  may 
form  the  basis  for  subsequent  work,  and  it  is  not  unlikely  that  some 
important  and  valuable  medicinal  plants  may  be  established  in  these 
comparatively  unexplored  and  interesting  islands.

In  this  first  part  of  the  second  volume  are  considered  the  ana- 
tomical elements  of  the  rhizomes  and  their  characteristics  in  the 
study  of  this  class  of  drugs ;  also  the  microscopical  characteristics 
of  calamus,  aspidium,  galangal,  hydrastis  and  iris.  The  present 
part  merits  the  same  commendation  that  the  previous  parts  that 
have  been  issued  have  received  in  this  Journal.
