diffeminated into the tunicles, They have on each fide one proper mufcle, called 
cremafter or fufpentfor : and a common mutcle, from the membrane of the {crotum, 
called dartos.. The tefticles have alfo feveral tunicles, coats, or coverings ; of which 
_ two are common: three proper to themfelves only. The firft common coat (which. 
is to defend the part) is conttituted of the fkin and fcarf-fkin, and is called fcrotum_ 
or burfa fcroti, becaufe it is like a purfe or bag: it is foft, wrinkled, and void of fat: 
having i in its lower part a line, according to the length thereof, which divides i into 
a right and left part, and is called jutura, or a feam. The fecond common coat 
confifts of a fielhy membrane, f{pringing from the membrana carnofa, which is here 
thinner than in other places, and full of veins and arteries, and is called dartus: : this 
‘by many is comprehended under the term fcrotum. The firft proper coat is called - 
vaginalis, the {cabbard coat ; and elicoides, from its thinnefs, which is yet ftrong and 
full of veins, arifing from the procefles of the peritoneum, and cleaving to the © 
dartos by many membranous fibres, whence its exterior part is rough, its interior 
fmooth. The fecond proper coat is called erythroides, becaufe of its rednefs ; it has 
fome flefhy fibres from the cremafter, from which it is propagated, and is fpread over 
the vaginalis. - The third and innermoft, called albiginea, arifing from the coat of the 
ipermatic veffels, immediately encompafies the. fubftance of the ftones, and as_it 
were binds the fame, being white, thick, and {trong, . The ufe of the tefticles is to 
elaborate the feed, and to make it, by their heat and inbred faculty : for the efficient 
caufe of the feed is the proper parenchyma of the tefticles, both in regard of their hot 
and moift temper, and of their {pecific property; for, the blood being prepared, 
they convert it into feed; what remains over and above ferves for nourifhment. of 
the part, and the remainder is conveyed back, by the fpermatic veins, to the 
The vafa deferentia, are the veffels carrying away the feed, and thefe begin at the 
tefticles, and end at the root of the yard, whither they carry and ejaculate the fe- 
minal humour; being in number two, on each fide one. Now thele vafa dg deferentia, 
ae 1 alfo meatus feminales, are divided into three parts; the beginning, middle, 
lend: under which are comprehended, the paraftrate, the vafa ejaculatoria, | the 
t feminales, and the profate. The paraftraie, or affiftants, are the beginnings 3 
the vafa defer entia, Their fubftance is of the middle Nature, between that of 
the ox Ghicien and. that of the vafa gjaculatoria, being within glandulous and fpungy, 
but without membranous. They have their origin in the ftones, making many 
anaftomofes there, with the wafa preparantia, by means of innumerable fmall pipes, 
or white fibres. The ule of the paraftrate is to perfect and finifh the feed, bya 
virtue which they receive from the tefticle, and, while the feed is lodged i F ee
