avoid wounding that organ, and with much diffi- 
culty could part it from it. I met with no fluid in 
the pericardium. The heart was fmall ; and in the 
internal fide the pores of the pericardium appeared 
fo large, that one might have inlinuated the head of a 
middling pin into them. They have been defcribed 
by fome anatomifts, who have met with cafes fome- 
what fimilar to this, but without fuch univerfal ad- 
hefions j and they have been luppofed to have been 
glands. The fame pores likewife appeared on the 
heart ; which, in my opinion, are nothing but the 
extremities of the exhaling vertels. In removing the 
heart, I found the dorjdl , and other lymphatic glands 
above the lungs, quite large, indurated, and of a 
dark greyifh colour. Nothing remarkable appeared 
in the lungs j only, that the portion of the pleura , 
which inverts the lungs, and is generally thin, was 
here thick and rough ; and thro’ a glafs it appeared 
as if covered with grains of fand ; and might in fe- 
deral places have been eafily torn from the lungs. 
7'he aorta was pretty large ; and in that part of it, 
which runs on the tenth dorfal vertebra , I found a 
cyftis , as big as an olive, full of pus ; and lower 
down, immediately before that veflel perforates the 
diaphragm, I found another, fomething lefs, full of 
matter likewife ; both which portions 1 have by me. 
That portion of the aorta , where the cyjlis appeared, 
was rather thicker than the other, and ofleous. In 
opening the cranium , I found in that part of the ce- 
rebrwn , which lies over the cerebellum , a table fpoon- 
full of pus , of a greenifh colour ; and examining it 
thro’ a glafs, there was an appearance of animalcula 
in it.
