CO NT 111 BUT IONS TO THE PATHOLOGY AND 
brane was pale. The kidneys were large, healthy, and firm in 
structure; ureters and urethra healthy also. 
Nervous System .—The substance of the brain was firm and 
natural in colour, and its vessels free, or nearly so, of blood. The 
spinal marrow was also free from any anormal state. The nerves I 
did not particularly examine. 
Organs of Respiration .—The nasal passages were darker in 
colour than natural; this darkness was greater about the larynx 
and pharynx than either in the trachea or the bronchial tubes. The 
vessels common to the mucous membrane of the trachea were much 
injected, and the membrane itself was shadowy. The appearance 
throughout the bronchial tubes was much the same. Both lungs 
were free from disease, their structure or substance was crepitous 
throughout: the left lung was a little congested with blood, and 
for about half its depth it adhered to the pleura costalis ; the right 
lung was also adherent in the same way for about three parts of its 
depth : the adhering substance was of a dirty yellow-brown colour; 
it closely resembled curd, and it was arranged in long string-like 
portions, which crossed each other in many directions, thus giving 
the appearance of very coarse net-work : at the bottom of the 
chest, over the superior surface of the sternum, this substance was 
more than half an inch in thickness. The separation between this 
substance and the lungs was easily effected, but some difficulty 
was experienced in detaching it from the pleura costalis, and, 
when T did effect its removal, the pleura was far from presenting 
that diseased appearance which I had anticipated : it presented 
very little change, save for about six inches at the bottom, on both 
sides, and along its entire length, which parts were entirely gan¬ 
grenous : the gangrenous portion did not commence abruptly; the 
natural colour passed by almost imperceptible gradations into the 
deep green. A portion of the inferior part of the thoracic surface 
of the diaphragm was covered with the curdy lymph, and the chest 
contained about six quarts of water, in which portions of lymph and 
pus were present. The mode by which the lungs were connected 
with this curdy lymph to the pleura is, I think, worthy of note. 
Let the reader imagine this lymph to be arranged in a trellis-like 
fashion, against which place the convex surface of the lungs; and, 
further, imagine this convex surface to adhere to the many pro¬ 
jecting surfaces of this trellis work, and he will form a very com¬ 
plete idea of the mode in question : he will perceive that the 
connexion would not be continuous, and that spaces would neces¬ 
sarily exist between these numerous points or surfaces of union. 
The curdy lymph was not arranged with that precise regularity 
which trellis work usually is, neither were the spaces at all 
uniform with respect to their size with one another; but the above
