skinos.  The  peasants  carry  the  wood  of  this  tree,  packed  upon  asses, 
into  the  towns,  where  it  is  sold  to  bakers  for  heating  their  ovens.  In 
the  island  of  Scio  (Chio),  where  also  the  species  yielding  pistacia  nuts 
and  mastic  are  found,  incisions  are  made  into  the  turpentine  pistacia, 
;md  the  exuding  oleoresin  is  collected  in  large  shells  and  in  clay  ves- 
sels fastened  beneath  tlie  incisions;  occasionally  this  turpentine  in 
oyster  shells  is  offered  in  the  bazaars. 
A  similar  exudation  is  the  Cyprian  turpentine,  to  some  extent  col- 
lected in  Cyprus,  and  the  plant  is  found  throughout  Greece,  where, 
however,  it  is  not  incised.  The  soil  in  the  neighborhood  of  such 
plants,  which  had  been  wounded  or  cut  down,  I  have  sometimes  found 
mixed  with  resin,  and  believe  that  a  turpentine  like  that  of  Scio  and 
Cyprus  may  also  be  obtained  in  Greece.  During  the  coming  summer' 
a  sufficient  quantity  will  probably  be  collected  to  supply  the  demands 
of  commerce.  X.  La^derer. 
CONCENTEATED  SOLUTION  OF  QUINIA. 
Fort  Brown,  Texas,  March  25,  1881. 
Editor  American  Journal  of  Pharmacy. 
Dear  Sir: — I  notice  in  the  March  number  of  the  "journal,'^  page 
136,  a  formula  for Lent's  solution  of  quinia,^' for  hypodermic  use» 
It  is  not  stated  when  it  was  first  used,  but  the  formula  is  almost 
identical  with  a  solution  I  first  made  in  May,  1874,  for  e very-day  use 
in  giving  that  remedy  in  the  Post  Hospital  at  Fort  Stockton,  Texas,, 
(the  formula  for  which  I  had  the  honor  of  furnishing  you,  with  the 
request  that  you  would  publish  it  for  the  benefit  of  the  pharmacist, 
especially  in  the  army,  but  it  was  never  noticed.^) 
At  the  time  I  constructed  mv  formula,  I  had  never  seen  one  of  a 
strength  exceeding  30  grains  to  f^i,  and  even  that  was  called  a  con- 
centrated solution.  I  have  continued  using  my  solution,  which  I  have 
no  difficulty  in  keeping  any  required  length  of  time,  and  their  is  no 
crystallization  except  in  very  cold  weather,  and  then  it  is  redissolvecL 
very  readily  by  warming. 
My  formula  is  as  follows : 
Be    Uuinife  sulphat.,     ....  grs.  480 
Acid.  Hulpliur.  dil.,       .  .  .  f^vi  to  f^i 
(xlycerinai,  ....  f^vi 
A(iu8e  distill.,  ....  ad  fjvi 
Misce  sec.  art.  and  filter. 
^  We  have  no  recollection  of  ever  having  received  the  letter  referred  to, — 
Editor.
