Non-Proprietary  Preparation : 
Radium  Sulphate,  Standard  Chemical  Co. — Radium  sulphate  sup- 
plied in  the  form  of  a  mixture  of  radium  sulphate  and  barium  sul-

Pure  radium  sulphate  occurs  as  a  white  substance  insoluble  in 
water  and  dilute  acids. 
The  presence  of  radium  may  be  qualitatively  determined  by 
electroscopic  or  by  photographic  means. 
The  radium  content  may  be  determined  as  in  the  case  of  radium 
chloride. 
Warning  to  Users  of  Turpentine  for  Medicinal  or 
Veterinary  Purposes. 
As  the  result  of  an  investigation  by  the  U.  S.  Department  of 
Agriculture,  it  has  been  found  that  the  adulteration  of  turpentine 
with  mineral  oils  is  so  widespread  that  druggists  and  manufacturers 
of  pharmaceutical  products  and  grocers'  sundries  should  exercise 
special  caution  in  purchasing  turpentine.  Those  who  use  turpentine 
for  medicinal  and  veterinary  purposes,  unless  they  are  careful, 
run  the  risk  of  obtaining  an  adulterated  article  and  unnecessarily 
laying  themselves  open  to  prosecution  under  the  Food  and  Drugs 
Act. 
It  has  been  found,  moreover,  that  the  turpentine  sold  to  the 
country  stores  especially,  as  usually  put  out  by  dealers  and  manu- 
facturers of  grocers'  sundries,  is  often  short  in  volume  by  as  much 
as  5  or  i o  per  cent.  Dealers,  therefore,  should  also  protect  them- 
selves through  a  guarantee  from  the  wholesaler  that  the  bottle  con- 
tains the  full  declared  volume. 
The  Department  has  found  that  turpentine  may  be  adulterated 
in  the  South  where  it  is  made  and  that  the  further  it  gets  from  the 
South  the  more  extensively  and  heavily  it  is  adulterated. 
In  all  cases,  druggists,  manufacturers  and  wholesale  grocers 
should  satisfy  themselves  that  the  turpentine  is  free  from  adultera- 
tion and  is  true  to  marked  volume.
