Dr. Granville’s essay on 
membranes and ligaments less surprising, which allowed 
us to impart to the great articulation of the thigh with the 
ilium, its various movements, a circumstance seldom ob- 
served, even in modern preparations of the pelvis. 
Some of the dissected muscles, as well as the denuded 
pelvis itself, will be submitted to the inspection of the Fellows 
after the Meeting of the Society.* 
The cavity of the thorax was next examined, and this I 
effected without disturbing the anterior portions of the ribs 
or breast bone, by simply detaching the diaphragm all round, 
and bringing it away. It was found that the pericardium, 
which adhered partially to the diaphragm, came away with 
it, and that a laceration had taken place at the same time in 
that sac. 
This circumstance denoting that the heart was present, I 
introduced my hand to remove it, when it was found sus- 
pended, in situ, by its large blood vessels, in a very con- 
tracted state, attached to the lungs by its natural connections 
with them. The latter organs adhered throughout their 
posterior surface to the ribs, and were brought away alto- 
gether in as perfect a state as could be effected. 
. All these various parts are accurately represented in Plate 
XXIII. fig. 1, 2.t 
The last cavity examined was that of the cranium ; for 
this purpose it was sawed in two, horizontally, and when 
♦ Among the detached muscles exhibited in the most distinct manner, there 
were the triceps femoris, the sartorius, portion of the vastus externus, and the 
principal abdominal muscles. 
f All the parts represented in Plate XXII. and XXIII, were exhibited after the 
meeting, to the Fellows and Visitors present, on three successive Thursdays.
