The following simple method of computing the 
amount of a liquid drug to be used may be found 
useful when preparing solutions for purposes in 
which absolute accuracy is not necessary. 
One pint, liquid measure, contains seventy-six 
hundred and eighty ( 7 , 680 ) minims—(g) 16 X 
(3) 8 X (m) 60 = (m) 7 , 680 —. 
Multiply the number of minims by the per 
cent solution required and the result gained will 
be the amount of drug in minims for each pint 
of solution. Divide this sum by sixty ( 60 ), the
