Sp.  Gr.  0.735  t0  0.720  has  necessitated  the  redetermination  of  the 
whole  of  the  figures  relating  to  solubility  in  this  menstrua. 
The  medicinal  properties  have  been  entirely  revised  and  brought 
thoroughly  up  to  date  by  the  inclusion  of  many  references  up  to  the 
end  of  the  year,  and  no  single  important  reference  to  an  official  or 
generally  used  unofficial  substance  has  been  omitted. 
Doses  are  given  in  both  the  imperial  and  metric  systems,  and  are 
those  generally  used  by  the  medical  profession.  In  the  case  of  toxic 
drugs,  reference  is  also  made  to  the  maximum  single  or  maximum 
daily  dose  given  in  a  continental  pharmacopoeia. 
The  prescribing  notes,  which  perhaps  are  the  most  useful  feature 
of  Squire's  Pocket  Companion,  as  they  appeal  both  to  the  prescriber 
and  to  the  dispenser,  have  been  systematically  revised  and  con- 
siderably enlarged.  Typical  instances  appear  under  Acidum  Boricum, 
p.  22 ;  Acidum  Carbolicum,  p.  28 ;  Iodine,  p.  478 ;  Pituitary  Gland, 
p.  637 ;  Salvarsan,  p.  734 ;  Tinctures,  p.  885.  Many  excellent  methods 
of  exhibiting  drugs  are  embodied  in  these  prescribing  notes. 
The  paragraphs  on  incompatibles  and  antidotes  have  been  brought 
into  complete  accordance  with  modern  knowledge  and  requirements. 
A  chapter  on  therapeutical  agents  of  microbial  origin  has  been 
completely  revised  and  almost  entirely  rewritten  by  Professor  R. 
Tanner  Hewlett,  Professor  of  Bacteriology  in  the  University  of 
London,  and  includes  up-to-date  information  on  antitoxins,  serums, 
tuberculins,  vaccines,  etc. 
Immediately  facing  the  first  page  of  Materia  Medica  is  a  list  of 
the  important  alterations  in  the  new  British  Pharmacopoeia,  1914, 
and  each  separate  monograph  is  clearly  distinguished  by  a  bracketed 
sub-title,  thus,  [new],  [modified],  [altered],  etc.  Typical  mono- 
graphs may  be  selected  from  the  following  examples:  Acid  Acetyl 
Salicylic,  p.  10;  Adrenalinum,  p.  72;  Chloral  Formamidum,  p.  257; 
Diamorphinae  Hydrochloridum,  p.  324;  Methyl  Sulphonal,  p.  545; 
Theobrominae  et  Sodii  Salicylas,  p.  847;  a  typical  example  of  a  not 
official  preparation  appears  under  Pituitary  Gland,  p.  633. 
Squire's  Pocket  Companion  is  a  handsome  volume,  bound  in  red 
leather,  with  flexible  covers,  and  gilt-lettered.  It  is  printed  on  India 
paper  from  entirely  new  type.  Notwithstanding  that  it  contains 
some  274  pages  more  than  the  first  edition,  it  is  a  considerably 
smaller-sized  book.  It  gives  the  prescriber  and  dispenser  a  system- 
atic and  complete  account  of  all  the  additions  and  alterations  to  the 
British  Pharmacopoeia,  1914,  complete  and  up-to-date  information
