Thefe two hydatide bags were behind that repre- 
fented in Fig. 2. (letter b.) which I took for an im- 
perfect eye, becaufe it was tranfparent, and fur- 
rounded by teguments not unlike eyelids. 
On tracing the fpine , and diverting it of all the 
foft parts, we difcovered that it terminated above in 
a bony mafs, that refembled the larynx , above which 
was a large foft fubftance of the confidence of, and 
covered with, that kind of fkin common to a cow’s 
udder j on which we faw hair like that of other 
children. This occupied, the ufual place for the 
head. 
Under this kind of parenchymatous fubftance, which , 
was white and glandular, was a mufculkr mafs, more 
confiderable and confpicuous than one could welL 
have expeCted in fuch a fubjeCt. It doubtlefs con— 
lifted of the occipital and perhaps frontal mufcles,, 
drawn towards each other.. 
Having raifed this flefhy part, I opened the upper 
bag of the fpine , refembling a larynx. Its furface 
was altogether bony, as ufual in the foetus, viz. 
fomewhat cartilaginous. This I opened in the di- 
rection of a membranous triangular line, fomewhat 
like the lambdoidal future of the occiput * We. 
found this kind of larynx fitted with cerebrum , or 
rather cerebellum ; it might be about a cubical inch in 
proportion 5 and this was all the brain of the foetus. 
At the extremity of this cavity, backwards, lay 
the proper medulla fpinalis. This cavity was not 
feparated by an elongation of the cerebellum , it had 
but a very fmall falx forwards; and on the right 
fide was another appearance of an elongation of the 
cerebellum ,
