difcharge and depofit their former contents tinder 
the neighbouring integuments, under the aponeurofis, 
or tendinous expanfion of a neighbouring mufele r 
or ftili more deeply under the mufcles themfelves ; 
the natural confequence attending this accident will 
fooner or later be a degree of elevation, or tumor 
which lpecies of tumor is known by the term 
aneurifm* 
If a true aneurifm happens, that is, a fwelling 
arifing from a general weaknefs of the coats of an 
arterial veffel, or from a wound or rupture of fome 
of its coats, it may be often diflinguifhed from a 
tumor proceeding from any other caul'e by a degree of 
pulfation, fuppofing the fituation of the injured 
veffel be fuperficial ; as may be evinced in recent 
aneurilms of the humeral artery, which fometimes- 
happen from bleeding near the bending of the elbow- 
joint ; as well as in aneurifms of the inferior part 
of the radical artery, of the ulnary artery, or of the 
anterior artery of the leg called tibialis antica j and 
as may be obferved to be fometimes the cafe too in 
thole arteries, whofe fituations are not fuperficial ; to 
wit, in aneurifms of the aorta afcendens , the curva- 
ture of the aorta , and of the carotides. 
The fymptom of pulfation in tumors, which take 
their rife from a partial wound* or from a geilerai 
weaknefs, and fubfequent dilatation of the coats of 
an artery, is not confined to this fpecies of aneurifm, 
but is frequently attendant upon falfe aneurifms 
(that is, fuch tumors, as are occafi'oned by extrava- 
fated arterial blood), fuppofing the difeafe to be a 
recent one of either of the preceding veffels, or ol 
any other arterial veffel not deeply fituated : and
