ence  of  phenol,  nor  is  the  quinia  salt  affected  by  ammonia,  in  certain 
proportions.  The  salt,  which  possesses  considerable  antiseptic  proper- 
ties, has  the  formula  C20H24N2O2,SO3.C20H24N2O2,C6H6O+7H2O, 
the  water  is  given  off  at  a  temperature  of  1500  C  (3020  F.).  It  is 
more  soluble  in  water  than  quinia  sulphate,  but  almost  insoluble  therein 
in  the  presence  of  free  phenol ;  sulphuric  acid  renders  the  salt  very 
soluble  without  separating  phenol,  but  diminishes  the  fluorescence  con- 
siderably. 
The  insolubility  of  sulphate  of  phenol-quinia  may  serve  to  separate 
this  alkaloid  from  cinchonia,  the  sulphate  of  which  does  not  produce 
an  insoluble  compound  with  carbolic  acid. — V  Union  Phar.,  1876,  pp.

To  color  arsenic  for  ordinary  sales  as  a  rat's  bane,  Grimaud  of 
Poitiers  proposes  to  mix  98  parts  of  arsenious  acid,  and  one  part  each 
of  ferrous  sulphate  and  potassium  ferrocyanide,  all  in  the  state  of  fine 
powder.  The  mixture  assumes  a  light  blue  color  and  is  said  to  possess 
an  odor  of  bitter  almonds,  without  interfering  with  the  poisonous 
properties  of  the  arsenic. — Bull.  Comm.  del' Union  Phar.,  1876,  16. 
Fowler's  Solution. — Having  observed  a  gradual  deposition  of  arsenious 
acid,  Mr.  Ch.  Meniere  kept  100  grams  of  this  preparation  for  three 
years,  and  then  collected  from  it  15  centigrams  of  arsenious  acid,  which 
had  been  deposited  in  the  form  of  needles  upon  the  separated  volatile 
oil. — Rep.  de  Phar.,  1876,  65. 
Quinia  in  Hypodermic  Injections. — S.  Limousin  has  found  that  the 
acid  hydrobromate  of  quinia  has  the  composition  C20H2iH2O2,2HBr. 
3H20,  and  is  soluble  in  9  parts  of  water  at  150  C  (59°F).  The  neu- 
tral salt  C20H24H2O2.HBr.H2O  is  less  soluble  than  the  ordinary  quinia 
sulphate.  The  corresponding  sulphovinates,  however,  which  the  au- 
thor proposed  for  use  in  hypodermic  injections  in  1 873^  contain  about 
the  same  amount  of  quinia  as  the  corresponding  hydrobromates  (75  to 
76  per  cent,  quinia  in  the  neutral,  and  56  to  60  per  cent,  in  the  acid 
salt)  ;  but  they  are  more  soluble  than  the  latter,  which,  however,  are 
preferable  in  all  such  cases,  where  the  effects  of  bromine  are  likewise 
needed. — Ibid.,  113,  115. 
Salicylic  Acid  in  Solutions  for  Hypodermic  Injections. — S.  Limousin  has 
observed  that  a  solution  of  0*20  grams  of  morphia  hydrochlorate  in  10 
grams  of  distilled  water,  was  spoiled  in  three  weeks  with  the  separation
