tion, dropping down bodily, and expiring. 
The lesions produced throughout the whole extent of the digestive 
canal by the action of the emetic tartar are various : the most 
general is vascular congestion of the mucous membranes to a 
greater or less degree, from the simple arborization, in isolated and 
circumscribed patches, to a deep red or even black hue, diffused 
throughout a vast extent. 
This congestion has nothing specific about it, so long as it is pro- 
duced by a perfect solution of the emetic in a quantity of fluid ; it 
then resembles all those erythemata of the intestinal canal caused 
by its contact with any irritating substance. But when the anti- 
mony administered is only held in suspension under the form of a 
coarse powder, and in too small a quantity of fluid to permit it to 
dissolve, the congested mucous surface then frequently presents a 
decidedly specific character : each grain of the salt leaves its im- 
press upon the part with which it came in contact, by transforming 
its epithelium into a circular scar, which, detaching itself, leaves 
behind a greyish and isolated or confluent ulceration, according to 
the quantity of the salt given and its state of dissolution. 
This peculiar kind of alteration, — which is in fact one of the pro- 
perties of the action of all caustic salts, divided into multiplied 
fragments of minute dimensions, — is especially manifested when the 
medicine is given in a solid state, in any sticky substance, such as 
honey. Its action then, even when given in the most concen- 
trated doses, is exercised on the same place ; and this spot is trans- 
formed into an eschar, the dimensions of which often exceed that 
of a five-franc piece. This eschar is of a greyish black hue, thick 
in substance, and formed from the whole of the mucous membrane, 
frequently encroaching on the subjacent cellular tissue, and some- 
times even on the muscular membrane : the adjacent parts are 
strongly injected with red, and the demarcation separating them 
from the eschared parts presents a yellow tinge. 
At a more advanced period of the disease, a fossa occupies the 
depth of this yellow ridge, in consequence of the inflammation, 
which becomes developed in the living parts, for the elimination of 
the eschars ; and, when we study the condition of the organs at 
the period of completion of the work, we find the surface of the 
intestinal mucous membrane presenting great loss of substance, 
arising from ulcerations, whose bases consist of an agglomeration 
of little fleshy granules of a greyish hue, which form the basis of 
the cicatrization, in those cases where life can be sustained while 
lesions of so grave a nature exist. 
Inflammation of the digestive mucous membrane is less fre-
