ON EXCIPIENTS FOR PILLS. 
201 
excipient is further illustrated in specimens of croton oil pills, as Nos. 4 and 
5, and again in combining ol. menth. pip. or other oils in such masses as ferri 
sulph. and pil. galban. co. (M). In making ext. colchic. acet. and ext. can¬ 
nabis into pills (when permitted), pulv. tragac. is a most convenient excipient, 
a good plastic mass is formed, and pills thus made retain their shape a long 
time (No. 6 ). With respect to calomel pills, I have found manna the best 
medium for making them, as specimen No. 7. The pil. ferri iodid. of the B. 
P. will not keep long unchanged ; but by a slightly modified process, con¬ 
taining the same quantity of iodide of iron, they may be made to keep any 
length of time unchanged, as evidenced by the sample in the tin box made 
two years ago. Mr. H. has not revealed the means by which lie has effected 
this object, but I know" the same may be accomplished by coating the pills 
with tolu.
