again towards the neck of the bladder, and fo ipxCs into the 
two Vagincey which lie under the Urethra ^ from this angle of 
refleflion, the cavity of each Uterus gradually leffens, and is 
much Imaller than the other parts of the Uterus^ the capacity 
of each Uterus beingr the largeil at the external bending, where 
it begins to be reflected j for here it was made, as it were, one 
common cavity for almoft the length of an inch 5 but on the 
infide, there was a membrane projeded from the mternal fide 
of the Uteris juft from the corner, where the (ides of the 
Uteri are doubled, whereby this cavity is in part divided 3 and 
for this reafon, the membrane may be called the fecond, or 
an im^cv^QSi i)iaghragm of the Uteri: In thefe Uteri, Dr. 
^yfon obferved four large trunks of blood-veffcls, which ran 
their whole length, fending from their fides numerous branches 
and ramifications ail along 5 thefe trunks were propagated frorn 
the hypogaftric and fpermatic verfels^ he alfo obferved here in 
thefe Uteris extended by inflation and dried, feveral FafcicuU 
of mufcular fibres, placed at a regular diftance from each other, 
and which likewife ran the whole length of the Uteri, by whofe 
contraction the Fmus may be more eaSly protruded : The two 
Uteri empty themlelves iuto the two Vagitide 3 for at this ex- 
tremity, the Uteriy making a turn at the neck of the bladder, 
are continued thence into the two Vagin<e, which He jufl under 
the Urethra, and are much of the fame length therewith, which, 
was about an inch 5 their capacity was about the bignefs of a 
wheat-ftraw 5 both thefe Vagin£ and the Urethra too, emptied 
themfelves into a common paffage, which was as large as all 
the other three, and about an inch and a half in length , it 
Ihewed reddifh, by means of its numerous blood- vcfllls, and 
at laft had its exit fo near the fundament, that, when alive, 
no other Forariien was obferved externally, but that which led 
into the ReBum 5 but upon diCfedtion, by elevating the Ikia 
here, which feemed to cover it like a valve. Dr. Tyfon obferved 
the Foramen, that led into this common paffage, and putting a 
blow- pipe into it, he at the fame time inflated the bladder of 
urine, and the uterine parts too; mzi. the Vagina, the Uteris 
and the Cormia 3 fo that in the fkin here, there was only one 
Foramen for the Fdsces, the urine, and the Fxtus. 
The Skeleton of the head, from the end of the Occiput to 
the extremity of the 'Nares, was four inches and three quarters 
long, of which the Roftrum, or fnour, meafured three inches, 
and juft where the fnout and Cranium met, the bones were lo 
pinched in at the fides, that here it was very narrow 3 and it
