AmseTpt"r'i9'i8.nn'  }    The  Manufacture  of  Aspirin  Tablets.  641 
from  tests  involving  the  physical  operation  of  making  an  aspirin- 
tablet.  As  these  tests  were  made  from  tablets  of  different  manu- 
facture and  as  various  manufacturers  improve  their  product  from 
time  to  time — as  such  improvement  becomes  possible, — it  would  be 
unfair  to  give  the  name  of  the  manufacturer  in  any  of  the  following 
cases.  We  will,  therefore,  in  our  future  consideration  designate 
them  by  number.
