PHARMACEUTICAL NOTICES. 
The following formula, which is very easy of execution, 
is proposed, viz : 
Take of Buchu leaves, - 8 ounces, (Troy.) 
. . Alcohol, - - 1 6 fluid ounces, 
Water, - - a sufficient quantity. 
Reduce the leaves to coarse powder, moisten them in a 
covered vessel, with twelve fluid ounces of the alcohol, 
macerate them for six hours, and introduce the whole into 
a suitable displacer. When the clear fluid has ceased to 
drip, add the remaining alcohol mixed with four fluid ounces 
of water, gradually, until the displaced alcoholic liquid 
amounts to twelve fluid ounces, which is set aside until re- 
duced to six fluid ounces by spontaneous evaporation. The 
residue in the displacer is then treated with a pint of cold 
water, by maceration for twelve hours, and subjected to 
pressure until a pint of aqueous liquid is obtained. (Dis- 
placement may be resorted to, but the mucilage renders it 
ineligible.) This is evaporated to ten fluid ounces, mixed 
with the six fluid ounces of evaporated tincture, and after 
occasional agitation for several days may be filtered or 
strained; to remove the undissolved resinous and gummy 
matter. 
Thus prepared, it had a dark brown colour, a strong and 
rather purgent taste of Buchu, and is administered in doses 
of one or two teaspoonfuls, which represents half a dram to 
a dram of the leaves. 
I have prepared this fluid extract by evaporating the 
tincture to four fluid ounces, the infusion to eight fluid 
ounces, and then dissolving in the mixture eight ounces of 
powdered sugar by agitation. 
Dr. M. Clymer, who has used this preparation, and ap- 
proves of it, prefers the first formula to the last, as he finds 
the patients to whom it was administered had a disinclina- 
tion for sweet drinks.
