ABSTRACTION OF BLOOD, OR BLEEDING (ARTERIVTOMY.) 
Blood is abstracted by opening the conducting vessels, arterial 
and venous. When taken from arteries, the process is called 
arteriotomy ; when by the latter, phlebotumy. Some oleedinga 
include both these operations, as general scarifications of the soft 
parts, bleeding at the toe point, divisions of the vessels of the cor- 
nea, etc. B'ocd-letting is called local when it is practiced on or 
very near the affected part; and it is supposed to act more immedi- 
ately than general bleeding because it produces more effect with the 
loss of less blood. Local bleeding is, therefore, usually practiced 
on the minor branches of the arteries and veins, as on the tem- 
poral artery, the plate vein, the vena saphena, etc. Leeches are 
a means of local bleeding not often used by us in veterinary prac- 
tice; but there is no reason whatever why they should not be em- 
ployed. When applied to the eye, and occasionally to other parts, 
also, they adhere readily, abstracting blcod rapidly, and, there- 
fore, might be valuable aids in violent local inflammation. Cup- 
ping is also practiced, in France and other parts of the Continent, 
witn very large glasses, and it is there supposed to act remedially 
in many local inflammations. By general bleeding we under- 
stand the depletion of the system at large, and this we practice in 
extensive inflammations. 
Diwision of the temporal artery—The proper spot for either its 
puncture or division is directly where the vessel leaves the parotid 
gland, to curve upward and forward around the jaw, a little be- 
low its condyle. When it is punctured, it usually affords much 
blood; and in such case, enough having been obtained, divide the 
trunk, when, the receding portions becoming pressed by the in- 
teguments, and lessening by their own contractility, the hemor- 
thage is stopped. It should be punctured by a lancet; a fieam 
may fix itself in the bone. Its division can be readily made, also, 
either by a lancet or scalpel. 
Bleeding by the palate is also a species of arterio-phlebotomy, 
and is a very favorite spot for abstracting blood with most igno- 
rant persons, who vehemently recommend it in spasmodic colic cr 
gripes, and in megrims, In such cases, however, a want of knowl- 
edge of the anatomy of the parts has occasioned a serious hemor 
rhage to occur; it may prove a fatal one if the artery proper to the 
part be divided incompletely. The palatine artery and nerve rup
