RECherches  Chimioues  sur  I.ES  Quinquinas,  par  MM.  Pelletier  et 
Caventou:  Lues  a,  1' Academic  des  Sciences  le  n  Septembre,  1820.  Reimpres-

This  is  a  reprint,  issued  by  Dr.  J.  B.  De  Vrij,  of  the  chemical  researches  on 
quinine  by  Pelletier  and  Caventou,  who  gave  to  the  world  the  results  of  their 
studies  on  this  alkaloid,  and  to  whom  it  is  proposed  to  erect  a  monument  in 
front  of  the  Ecole  de  Pharmacie  de  Paris. 
Pharmaceutical  Formulas.  Collated  chiefly  from  The  Chemist  and 
Druggist  and  "  The  Chemists'  and  Duggists'  Diaries."  By  Peter  MacEwan. 
Pp.  664.  Price  8s.,  post  free.  London  :  The  Chemist  and  Druggist,  42  Can- 
non Street. 
This  is  a  book  of  useful  recipes  for  the  drug  trade,  and  comprises  formulas 
for  toilet  preparations  and  specialties,  preparations  for  the  hair,  dentifrices, 
perfumes,  household  and  culinary  requisites,  antiseptics  and  disinfectants, 
inks,  varnishes,  confectionery,  medicinal  compounds,  and  many  other  prepar- 
ations related  to  the  art  of  pharmacy.  "  One  feature  of  the  book  is  that  the 
contents  are,  in  a  great  measure,  based  upon  requests  for  more  than  a  genera- 
tion of  pharmacists  for  assistance  in  supplying  articles  for  which  they  could 
discover  no  recognized  formulas."  "The  information  so  collated  has  been, 
as  far  as  possible,  checked  by  experiment  and  reference  to  the  original  sources 
and  supplemented  by  private  formulas  which  have  been  abundantly  proved  in 
practice."  To  provide  for  great  differences  in  tastes,  a  great  many  different 
formulae  of  the  same  preparation  are  given.  The  editor  does  not  claim  that 
all  the  formulae  will  work  under  all  conditions,  but  says  this  with  regard  to 
formula  failures  :  "  Many  a  man  says  a  formula  is  bad  when  his  ingredients 
are  at  fault.  Weak  lime-water  does  not  emulsify  like  freshly-prepared  aqua 
calcis;  hard  paraffin  has  not  all  the  properties  of  beeswax,  nor  does  a  geranium- 
loaded  otto  of  rose  give  the  delightful  aroma  of  the  real  thing.  Such  devia- 
tions may  not  always  be  the  cause  of  failure,  but  they  often  have  something 
to  do  with  it,  and  manipulation  has  more."  The  formulas  published  in  this 
work  have  been  selected  and  in  many  cases  tried.  The  information  contained 
in  this  volume  will  more  than  repay  the  practical  pharmacist  in  having  it  in 
his  possession.
