CONTRI BUTTONS TO THE PATHOLOGY AND 
up, which it readily could be with the finger, it presented the gra- 
nular character so commonly seen in softened livers : the spleen 
was very small, and almost destitute of blood. 
Heart and large Vessels, fyc . — On exposing the pericardium, I 
found it and a portion of the left lung to be very closely adherent 
to one another ; the lung, in fact, adhered to both the pericardium 
and to the chest ; the adhesion was effected through the medium of 
the cinnamon-coloured coagulum. The external surface of the peri- 
cardium was smooth, and free from lymphy deposit; the pericardium 
contained about twelve ounces of serous deposit. The heart itself 
was firm in its structure, but very pale in colour : the surface of 
the left ventricle exhibited three small dashes, as it were, of a deep 
red colour, which appeared to be deposited between the lining mem- 
brane of the ventricle and the muscular substance of the organ. All 
the valves of the heart were healthy, as also were the large vessels 
in connexion with it. The heart, when divested of its fat and large 
vessels, weighed exactly seven pounds four ounces avoirdupois. 
That portion of the left lung adherent to the chest and pericardium 
was indurated, and contained, in addition, a cavity which was filled 
with a cheesy-looking matter ; the pleura, where the lung was ad- 
herent, was rough and thickened, from the existence of lymphy 
deposits. The lungs, as a whole, were far from being healthy ; the 
colour of their substance was bad; and great quantities of serous 
liquor followed every cut of the knife through their substance. The 
trachea contained a deal of frothy fluid; its mucous membrane was 
of a dirty white hue, and softened throughout : the colon and state 
of the larynx were much the same. 
Brain, fyc . — The brain I also examined, and found it of mode- 
rate firmness and clear in colour; but it appeared as free from blood 
as though the organ had been washed for my inspection. The spinal 
cord I did not examine. 
Coagulum . — I tested the cinnamon-coloured deposit both with 
nitric acid and by heating the substance to boiling in a test tube ; 
when I found the whole to consist of serum richly loaded with 
albumen. This serous substance existed in great abundance, not 
only where I have stated, but also in the cellular tissue between 
all the muscles of animal life which I examined. 
Case III. 
April 19 th, 1847. — I was requested, about nine o’clock A.M., to 
attend upon a mare, the property of Messrs. Sharpe and Welsh, 
railway contractors, in this neighbourhood. 
History . — The mare in question is of a grey colour, six years 
of age, and of the light draught breed. About ten days ago I was
