BISMUTH SUBNITRATE 



The advantages of unusual bulkiness and 

 other desirable qualities of our BISMUTH 

 SUBNITRATE can only be appreciated by 

 giving it a trial in the dispensing depart- 

 ment. Pharmacists who are not using our 

 brand should not fail to specify the same 

 and insist upon receiving original packages 

 bearing our label.
