this  connection  that,  after  reading  Dr.  Squibb's  rejoinder,  we  have  failed  to  be  con- 
vinced of  the  wisdom  of  his  plan  5  on  the  other  hand,  we  are,  and  have  been  for 
some  years  past,  convinced  of  the  necessity  of  a  reform  in  the  manner  of  revising 
the  Pharmacopoeia,  and  we  believe  that  that  can  be  successfully  accomplished  by 
the  National  Convention. 
Annual  Report  of  the  Entomological  Society  of  the  Province  of  Ontario,  for  the  year 
1876.  Printed  by  order  of  the  Legislative  Assemby.  Toronto,  1877.  8vo,  pp.  58. 
The  report  contains,  besides  an  account  of  the  proceedings  of  the  Society,  various 
illustrated  papers  on  blistering  beetles,  locusts,  moths,  beneficial  and  injurious  insects.. 
Dose  and  Price  Labels  of  the  Principal  Articles  of  the  Materia  Medica,  and  Prepara- 
tions used  in  the  United  States.    By  C.  L.  Lochman.    Allentown,  Pa.,  1877. 
The  labels  are  intended  not  to  replace  the  ordinary  shop  labels,  but  in  addition  to 
such  to  be  affixed  to  the  bottles  and  drawers,  and  to  serve  as  a  ready  reference  in 
regard  to  doses  and  uses.  Dangerous  medicines  are  intended  to  be  indicated  by 
two  heavy  black  lines  and  one  or  more  exclamation  marks  (!).  In  this  there  are, 
however,  some  notable  oversights :  the  poisonous  nature  of  Tinct.  opii  deodorata, 
which  is  of  the  same  strength  as  Tr.  opii,  is  not  marked  ;  we  should  prefer  to  place 
chloral  among  the  poisons ;  if  dilute  nitric  and  muriatic  acids  are  poisonous,  we 
should  think  that  dilute  sulphuric  acid  ought  to  be  placed  in  the  same  class,  etc. 
Most  of  the  labels,  in  which  typographical  errors  occur,  have  been  replaced  by 
others,  which  are  stitched  in  at  the  end  of  the  book.  The  use  which  at  present  can 
be  made  of  a  'abel  for  Rheum  Russicum  is  unknown  to  us. 
The  title-page  states  that  a  patent  has  been  applied  for  j  but  we  confess  to  our 
ignorance  as  to  what  there  is  patentable  in  the  work,  which  is  somewhat  similar  to- 
the  more  complete  label  book  published  some  years  ago  by  Mr.  George  Barber,  of 
Liverpool,  with  the  addition  of  the  black  lines  and  exclamation  marks,  to  indicate 
poisons,  which  we  can  hardly  believe  will  be  claimed  as  an  invention.

Contributions  to  the  chemistry  of  the  more  important  resins,  gum  resins  and  balsams.. 
The  experiments  for  these  valuable  "  contributions"  were  made  in  DragendorfPs 
laboratory.  We  regret  that  we  cannot  make  room  for  the  entire  dissertation,  but 
expect  to  give  a  brief  account  of  the  reactions. 
On  the  Physiology  of  Sugar  in  relation  to  the  Blood.    By  F.  W.  Pavy,  M.D.,  F.R.S. 
London,  1877.    8vo,  pp.  15. 
The  pamphlet  is  a  reprint  from  the  "Medical  Examiner"  of  two  communica- 
tions to  the  Royal  Society,  in  the  first  of  which  the  author  describes  his  method
