In  the  present  volume  Dr.  Osborne  has  devoted  a  limited  space 
to  a  discussion  of  the  general  chemical  and  physical  properties  of 
the  vegetable  proteins.  In  eleven  chapters  covering  about  100  pages, 
he  gives  a  historical  review  of  the  proteins ;  the  occurrence  of 
proteins  in  the  different  parts  of  plants  and  their  characteristics; 
the  isolation  and  preparation  of  seed  proteins ;  basic  and  acid 
properties  of  proteins ;  the  solubility,  precipitation,  denaturing, 
physical  constants,  and  products  of  hydrolysis  of  vegetable  proteins ; 
a  classification  of  vegetable  proteins ;  and  some  physiological  re- 
lations of  vegetable  proteins  to  the  animal  organism,  and  the  biolog- 
ical relations  of  seed  proteins  to  one  another.  The  book  is  en- 
hanced by  a  very  complete  bibliography  of  over  600  references 
and  has  a  good  index. 
The  Extra  Pharmacopoeia  of  Martindale  and  Westcott. 
Revised  by  W.  Harrison  Martindale,  Ph.D.,  F.C.S.,  and  W.  Wynn 
Westcott,  M.B.,  Lond.,  D.P.H.  Thirteenth  edition.  London:  H. 
K.  Lewis,  136  Gower  Street,  W.  C,  1908. 
This  useful  volume  has  undergone  a  thorough  revision,  many 
portions  having  been  entirely  rewritten.  Among  the  new  features 
may  be  mentioned:  formalyzed  gelatin  as  a  substitute  for  col- 
lodions ;  glycetracta  or  glycerin  extracts  of  drugs ;  the  preparation 
of  yellow  mercuric  oxide  ointment ;  the  organic  (non-toxic)  arsenic 
compounds ;  trypsin  preparations,  etc.,  etc.  A  number  of  new  sub- 
stances are  considered.  The  recent  literature  has  been  carefully 
gone  over  and  everything  which  is  likely  to  prove  of  value  to  the 
pharmacist  has  been  included. 
E.  Merck's  Annual  Report,  or  Recent  Advances  in  Phar- 
maceutical Chemistry  and  Therapeutics.  1908.  Volume  XXII. 
E.  Merck,  Chemical  Works,  Darmstadt,  1909. 
This  valuable  annual  report  contains  much  information  that  is 
not  to  be  found  readily  in  any  other  publication.  The  first  hundred 
pages  are  devoted  to  a  consideration  of  organotherapy  and  organo- 
therapeutic  preparations.  This  presents  an  exceedingly  interesting 
historical  review  of  the  subject,  and  also  contains  much  of  the  newer 
matter  relating  to  the  organic  preparations  obtained  from  healthy 
animals.  It  is  the  most  complete  treatment  of  this  subject  that  we 
have  seen,  giving  the  manner  of  preparation,  physical  and  chemical 
properties,  and  the  results  of  physiological  and  clinical  tests  of  all
