spinalis was not wanting in this fubje^]:, but that it fupplied 
the defefl both of the brain and Cerebellum^ and that the ani- 
mal fpirits were feparated therein, and diftributed for conti- 
nuing the circulation of the bloody for it is to be confidered, 
that altho' the intercoftal nerve and eighth pair have their 
origin in the Medulla oblofigatay yet after they enter into the 
cavity of the breaft, they are united with branches from almofb 
all the vertebral nerves, and together with them make up 
feveral plexus's, and from thofe plexus's feveral branches are 
emitted to the heart, and other parrs, fufficient for continuing 
the circulation of the blood ; and this has occafioned Ibme to 
fall into a miftake, thinking the circulation might be explained 
fome other way, than by the influx of the animal fpirits into 
the nerves, which they endeavour to prove by an experiment 
on a dog, by tying up the intercoftal and eighth pair of nerves, 
before they enter the cavity of the breaft, and yet the dog fhall 
live for two or three days after 3 but except they can tie up all 
the vertebral nerves, or at leaft tie up the nerves at their 
entrance into the heart, the experiment is not fo convincing ; 
and the fymptoms, which ordinarily happen, even upon tying 
the intercoftal and eighth pair, is an evident proof of the 
contrary, for the animal is immediately taken with convui- 
fions. 
Horns of American Deer found under Ground in Ireland, by 
'Dr, Tho. Molyneux. Phil. Tranf. N^ 227. p. 489.

head were as follows, from the extreme tip of the right horn 
to that of the left AB, Fig. 5. Plate VI. was 10 foot 10 inches; 
from the tip of the right horn to the root, where it was faftened 
to the head CD, 5 foot 2 inches; from the tip of the higheft 
branch (meafuring one of the horns tranfverfely, or directly 
a-crofsthe palm) to the tip of the loweft branch GF, 3 foot 
7 T inches ; the length of one of the palms, within the branches 
GH, 2 foot 6 inches; the breadth of the lame palm, ftiU 
within the branches IK, i foot 10 \ inches; the branches that 
/hot forth round the edge of each palm, were one in number, 
befides the brow-antlers, of which the right antler D L was 
I foot 2 inches in length, the other was much ftiorter; the 
beam of each horn M, at fome diftance from the head, was 
about 8 inches in cifcumference ; at the root, where it was 
faftened to the head^ about 11 inches in circumference; the
