PYAEMIA AND EMBOLISM. 
with the exception of the mesenteric glands. These were 
enlarged, but did not contain any pus. 
On cutting through the aorta and vena cava fluid blood 
rushed out ; but on opening the iliacs I found that the right 
external one contained several fibrinous clots, and that at the 
bifurcation of the arteria profunda and femoral arteries a firm 
clot completely blocked up the passage through these vessels. 
These clots were of various sizes and shapes ; they had a 
fibrillated structure, and presented an appearance of having 
been detached from some point of formation. The vessels 
were to all appearance healthy, and the clots had no attach- 
ment to their walls. 
The arteries on the left side were pervious. The blood in 
the abdominal aorta and its branches was fluid. In the left 
iliac veins it was firmly coagulated, even down to the femoral 
and popliteal and smaller veins leading into them. Through- 
out the entire body the blood seemed to have a tendency to 
separate into two portions — a brick -red and a yellow portion. 
In some parts of the veins the clot was formed of one colour, 
principally the red ; in others red and yellow, the yellow 
being always superficially placed. 
Thorax . — A quantity of straw-coloured fluid was contained 
in the pleural sacs, and the surface of the lungs presented, in 
some places, an indurated, and in others an emphysematous 
condition. In the infero-posterior part of left lung a cavity, 
communicating with a large bronchus and lined by a smooth 
membrane, and containing a quantity of muco-purulent fluid 
similar to what was in the trachea, was found. Throughout 
the substance, also, of the lung a number of smaller cavities, 
communicating more or less directly with each other, existed. 
The infero-posterior part of right lung was indurated and 
hepatized. On section it presented a number of tubercular 
spots, composed of cheesy-like matter. In its antero-superior 
part masses, varying in size from a hazel-nut to that of a 
chestnut, of a dirty-red colour, existed. In no [part of the 
chest was the pleura found to he adherent to the walls of 
the cavity, nor did it show any signs of inflammation. 
The heart was much enlarged, the pericardium was thick- 
ened, and contained an unusual quantity of fluid. The 
hypertrophy of the heart was most marked towards the base 
of the left ventricle ; at the apex it was normal ; the carneae 
columnae and chordae tendineae were thickened and studded 
with a number of fibrinous clots. The aortic valves were 
thickened, hard, and inelastic, especially at their free borders, 
on which w r ere also a few aggregations of fibrinous granula- 
tions. The mitral valves were roughened by deposits of
