ON EXCIPIENTS FOR PILLS. 
I have carefully prepared the formulae marked A. C. E. F. M. Nos. 4 and 5, 
they being the principal ones and dissimilar. I will now start with the fact 
before me that crumb of bread is the best excipient for these pills, excepting in 
such cases as the formula F, they requiring a different treatment. Liquorice 
powder is about the last thing I should have thought of using as an absoibent 
of creasote or moisture generally, there being several others very superior, 
—about the best of all being lycopodium.

Lycopod. gr. i.

Instead of being 6 to 7 grains, and no doubt difficult to roll, I have here 
six very nice pills of the ordinary 5-grain size, rolled out beautifully, and re¬ 
taining every particle of creasote.

Made up very nicely: 3 grains of bread quite sufficient, and tragacanth 
paste enough to make the oil and bread thoroughly homogeneous ; this being too 
soft to roll? lycopodium was added, they then rolled out tolerably well, and are 
very little larger than the ordinary 5-grain size, with all the creasote retained. 
E. Creasoti gtt. ij. 
Saponis gr. i. 
Micae Panis gr. iij. 
P. Tragac. Co. gr. iss. 
Ft. Pil. i. mvj. 
Being much too soft after mixing the three first, pulv. tragac. co. was added 
with the best effect; they rolled out well, are a very clean pill, but larger than 
any of the others, being the size of a large 5-grain pill. Creasote completely 
retained. 
F. Creasoti gtt. iij. 
Pil. Sapon. Co. gr. v. 
Lycopod. gr. i. 
Pulv. Tragac. Co. gr. i. 
Ft. Pil. ij. mxij. 
The two first making a semi-fluid mass, and lycopodium being not absorbent 
enough, I added pulv. tragac. co. again with good effect, as it made a good mass, 
rolled out well, and the two pills are of the usual 4|-grain size, against those 
of Mr. S. 1\ grains each. Creasote completely retained. 
M. Ferri Sulph. gr. i. 
Pil. Galb. Co. gr. iiss. 
01. Menthse gtt. i. 
Lycopod. gr. i. 
Ft. Pil. i. mvj. 
The first three made a mass too soft to roll; the lycopodium being added, it 
was then in a fit state to roll; makes ordinary-sized pills. 
No. 4. 01. Croton, gtt. i. 
Pil. Sapon. Co. gr. ij. 
Micae Panis gr. i. 
Ft. Pil. i. mvj. 
Made up very easily into small-sized pills.
