PHARMACEUTICAL  NOTES  OF  TRAVEL. 
face  from  which  I  have  already  quoted  closes  with  the  following 
significant  remark  :  "  As  economy  is  an  important  considera- 
tion in  the  choice  of  medicines,  cceteris  paribus,  the  Company  in 
this  publication  have  not  overlooked  it;  the  reader  is  on  this 
point  referred  to  the  articles  quinine  and  cinchona  barks  and 
rhubarb  in  the  sequel."  On  reference  to  these  we  find  the 
neutral  sulphate  of  quinine  recommended  as  an  improvement 
on  the  disulphate,  on  account  of  its  perfect  solubility.  Sul- 
phates of  cinchonine  and  quinidine  are  favorably  spoken  of ; 
ammoniated  solution  of  quinine  is  spoken  of  as  a  very  elegant 
preparation  ;  liquor  quinoidinse  sulph.,  dose  5  minims  and  up- 
wards, is  recommended  as  superior  to  sulphate  of  quinine,  as  an 
antiperiodic  against  fevers,  &c.  Citrate  of  quinine  and  iron  of 
this  make  is  said  to  contain  40  per  cent,  of  citrate  of  quinine,  a 
larger  percentage  than  usual.  Besides  these,  thirteen  salts  of 
quinine  are  spoken  of;  under  the  head  of  Valerianate  of  Qui- 
nine, Dr.  G.  B.  Wood  is  quoted  as  recommending  a  combina- 
tion of  Peruvian  bark  and  valerian.  I  may  remark  here,  that 
this  eminent  American  authority  is  well  and  favorably  known 
to  the  profession  in  Great  Britain,  where  his  book  on  "The 
Practice  "  is  actually  used  as  a  text  book  in  one  or  more  of  the 
colleges. 
English  rhubarb,  of  which  I  purchased  a  sample,  of  this 
Company,  is  recommended  in  "  The  Record  "  as  very  nearly 
identical  in  its  therapeutic  action  with  the  foreign  varieties ;  it 
is  stated  that  the  best  samples  of  English  yield  about  52  per 
cent  of  extractive  matter  to  cold  water,  East  Indian  53  to  54, 
and  Turkey  not  more  than  55  or  57;  and  that  when  the  differ- 
ence in  price  is  considered,  it  will,  it  is  trusted,  be  useful  to 
general  practitioners  to  be  supplied  with  so  cheap  an  article. 
Notwithstanding  this  statement  and  the  alleged  endorsement  of 
Dr.  Pereira,  I  found  no  reputable  druggist  andchemist  willing  to 
sell  it  as  equal  to  the  East  India  drug. 
Among  the  new  remedies  noticed  at  this  establishment  my 
attention  was  particularly  arrested  by  the  pyrophosphate  of 
iron  in  pseudo-crystalline  scales ;  this  preparation  is  stated  to 
contain  a  small  quantity  of  citrate  of  ammonia,  which  renders 
it  readily  soluble  in  water,  the  solution  being  nearly  tasteless  and 
permanent ;  it  is  recommended  in  doses  of  3  to  10  grains,  to  be
