ART. XXXII.— REPORT UPON A FORMULA FOR VESICA- 
TING TAFFETAS. Addressed to the Societie de Pharmacie, by M. 
Deschamps, By Cap & Soubeiran. 
{Translated by Augustine Duhamel.) 
In the Codex is found a formula for blistering taffetas given 
by M. Guilbert, in which are introduced garou or sain bois 
(Daphne Gnidium,) cantharides, euphorbium and myrrh. All 
these matters are treated by ebullition in water, and the li-

means of a brush. Few have adopted this formula, as the taffe- 
tas easily peel off soon after preparation. It might also be said 
that the menstruum had not been well chosen. In 1818 M. 
Drouot published a more satisfactory one; it is composed of 
a mixture of tinctures of garou and cantharides — made both 
with acetic ether; a little colophony is dissolved in the mix- 
ture and then applied with a brush upon gummed taffetas. 
The excellence of the formula has been proved by the Editors 
of the Journal de Pharmacie; they had to find fault only 
with the employment of acetic ether — which does not give 
more advantageous results than sulphuric ether and costs much 
more. 
We shall say as much in reproach of the formula which 
consists in dissolving the colophony in acetic ether, and mix- 
ing the cantharides in fine powder with this tincture; more- 
over, the powdered flies scattered upon the surface of these
