members of this Society, and excellent judges of this 
fubje(ft. M. Clairaut, fince our laft meeting, has 
been fo kind as to tranfmit to me their anfwer; by 
which it does appear, that this is prepared from a 
plant, which is called by the botanifts 
“ Agaricus pedis equini figura. Inft, Ret. Her bar. 
“ Fungus in caudicibus nafcens, pedis equini figura. 
C. B. Pin. 
“ Fungus durus arborum, five igniarius. P^ri. T'heat. 
Fungi arborei ad ellychnia. I. B. 
“ Fungi igniarii Cifalpini et Tragi. 
“ Boletus acaulis pulvinatus laevis, poris tenuiflimis. 
Linn. Flor. Suec. 
It is the agaric employed for the amadoue j and 
Mr. Broffart, who firfl: brought this preparation into 
practice, conceives, that that, which grows upon old 
oaks, which have been lopped, is the moft valuable j 
that it fhould be gathered in Augufl or September, 
and be kept in a dry room. 
The way of preparing it is to take off with a 
knife the white and hard part, till you find a fub- 
ftance fo foft, as to yield under the finger, like fham- 
my leather. This is to be divided into pieces of 
different fizes and thicknefs : beat thefe with a ham- 
mer, to give them a ftill greater degree of foftnefs, 
fo that they may be eafily torn with the finger. 
Mr. Morand thinks, that the agaric, which wFen 
growing is of a greyifh colour on the outfide, is bet- 
ter than that which is white.
