time  of  the  reflex  frog.  The  following  drugs  are  used:  'alcohol, 
ether,  chloroform,  chloral  hydrate,  the  opium  alkaloids,  caffeine, 
strychnine,  cocaine,  quinine,  atropine,  scopolamine,  nicotine,  curare, 
pilocarpine,  physostigmine,  aconite,  veratrine,  digitalis,  ergot,  supra- 
renal gland,  nitroglycerine  and  the  nitrites,  phenol,  potassium,  cal- 
cium, and  barium  salts. 
The  principles  involved  in  carrying  on  the  various  experiments 
are  discussed,  and  descriptions  of  apparatus  together  with  special 
methods  are  given  in  the  last  twelve  pages. 
It  is  a  timely  book  but  has  not  been  developed  along  the  prac- 
tical lines  of  testing  of  drugs,  such  as  are  given  in  Cushny's  labora- 
tory book. 
Les  Produits  Pharmaceutiques  Industriels.  Par  P.  Carre, 
Docteur  es  Sciences,  Preparateur  a  lTnstitut  de  chemie  appliquee 
de  Paris,  Tome  I  et  II.  Paris :  Octave  Doin  et  Fils,  Editeurs. 
8,  Place  de  L'Odeon,  8.  1909. 
This  is  a  valuable  laboratory  book  for  the  preparation  of  pharma- 
ceutical products.  Volume  I  is  devoted  to  the  consideration  of 
inorganic  compounds,  while  Volume  II  is  devoted  to  organic 
products.  It  has  been  developed  along  the  lines  of  many  of  the 
books  on  the  making  of  organic  preparations  which  are  used  in 
colleges  and  universities.  To  attempt  to  enumerate  the  substances 
which  are  considered  would  be  to  mention  every  important  product 
that  is  used  in  pharmacy  and  medicine.  It  is  a  particularly  welcome 
work  at  this  time,  as  many  of  the  standard  works  used  in  this 
country  are  deficient  in  manufacturing  processes,  and  the  retail 
pharmacist  is  seeking  just  such  information  as  is  found  in  these 
volumes.  It  is  indeed  encouraging  with  the  awakened  interest  in 
pharmaceutical  chemistry  for  a  work  like  Carre's  to  appear,  which 
is  both  practical  and  complete. 
Ferments  and  Their  Action.  By  Carl  Oppenheimer.  Trans- 
lated from  the  German  by  C.  Ainsworth  Mitchell.  London : 
Charles  Griffin  &  Co.,  Limited. 
This  is  probably  the  most  valuable  laboratory  manual  on  the 
enzymes  and  organized  ferments  that  has  been  published,  as  the 
references  to  the  literature  are  very  complete  and  the  selections 
admirably  made. 
In  the  general  part  are  chapters  on  the  history  of  ferments ;  defi-
