ether  before  mixing  with  the  paraffin  oil.  For  various  reasons  Dr. 
Ley  prefers  a  vegetable  oil  as  a  vehicle  for  hypodermic  injections,  and 
finds  that 
Purified  groundnut  oil  answers  the  purpose  well.  The  purification 
is  effected  by  bleaching  in  the  sunlight,  decolorizing  with  animal  char- 
coal, and  sterilizing ;  it  is  then  an  excellent  vehicle  for  volatile  oils, 
iodoform  and  phenol,  and  of  the  latter  rather  concentrated  solutions, 
— containing  from  3  to  10  per  cent,  of  phenol — may  be  used.  The 
phenol  solutions  are  made  with  the  aid  of  a  moderate  heat. 
The  therapeutic  equivalents  of  quinine  salts  was  the  subject  of  a  paper 
recently  communicated  to  the  Paris  Societe  de  Therapeutique  by  Dr. 
Boymond.  The  accompanying  table  gives  in  a  condensed  form  much 
information  of  great  practical  value  to  the  pharmacist  and  physician  :

The  figures  given  above  differ  to  some  extent  from  those  adopted 
by  the  French,  United  States,  and  other  pharmacopoeias. 
Resin  of  griaiacum  is  regarded  by  Sir  James  Sawyer  (Birmingh.  Med. 
Review,  Jan.  1887)  as  a  valuable  emmenagogue  in  a  large  proportion  of  cases 
of  amenorrhea  ;  it  is  given  in  doses  of  ten  grains,  stirred  in  a  wineglassful  of 
milk,  every  morning  before  breakfast.  The  ammoniated  tincture  of  guaia- 
cum  may  be  given  during  the  painful  period,  in  certain  cases  of  dysmen- 
orrhcea,  in  doses  of  half  a  drachm  to  a  drachm  in  a  wineglassful  of  water 
every  two  or  three  hours  till  the  pain  is  relieved.
