Upon the whole, thefe teach us, in the beft manner 
pofible, the true and intimate ftru€ture of the vifcera in 
general, and of every particular part; from whence we 
may affert, without fear of any juft cenfure, that prepara- 
- tions thus executed are exceedingly ufeful, and enrich the 
cabinet with choice and beautiful {pecimens of anatomy. 
I have only to add that, in order to enable the artift to 
fucceed and pufh his difcoveries, it behoves him to learn 
the art of preparing the fubje& by difleGtion. This is 
a new branch, though intimately connected with the 
foregoing: There are few books that teach it; but one 
very excellent treatife on the fubjec&t is publithed in French 
by Monf. Siie, already quoted by the title of anthropotomy, 
or the art of diflecting, injeting, embalming and preferv- 
ing the parts of the human body; which, as I think it 
will greatly contribute to improve anatomy, I have fome 
thoughts, at my leifure, to tranflate into Englifh, for the 
benefit of the ftudents of anatomy, phyfic and furgery in 
America. 
J here fubjoin the manner of making Wax Preparations by 
Mon/f. Site. 
<< HEN we have a mind to make any prepara- 
tion of wax, we ought to begin by moulding 
the part we with to imitate with freth plaifter of Paris 
made very fine, taking care to oil it previous to the appli- 
cation of the plaifter. 
“© When the plaifter laid on the furface of the part is 
cold, remove all the pieces that compofe the mould one 
after another, taking care not to break any of them.

MANIERE DE FAIRE LES PREPARATIONS EN CIRE. 
ORSQU’ON veut faire quelque preparation en cire, il faut commencer par mouler la 
L partie que l’on veut immiter avec du platre frais et bien fin, ayant l’attention de bien 
huillér la partie avant que d’appliquer le platre. Lorfque le platre fera refroidi de deffus la 
partie, alors on otera toutes les pieces qui compofent le moule, lune aprés|’autre, prenant garde 
qu’aucuns
