\yith in exfpiration, very little room was left for frefli 
air in infpiration; the lungs, from the emphyfema, 
and fiom the difeafed hate of the pulmonary vein, 
ruling almoh the whole cavity of the thorax. This 
not only occafioned an enormous defed in the quan- 
tity of air in infpiration necehiiry to the purpofes of 
hfe, but by the preternatural compreflion the motion 
of the blood was retarded in the lungs, more efpe- 
cially in their fmaller vefTels. This affeded not only 
the ferous extravafation in the cih before-mentioned, 
but occafioned thofe general obhrudions in the blood 
veffels of the lungs, which brought on the fphacelated 
appearance; and finally, by the increafe of the com- 
plaint, was the caufe of death. 
This extraordinary dihenfion of the lungs accounted 
for the heart’s being of a more compreffed°figure than 
is ufually feen. 
In the prefent inhance an ahhma was occafioned 
by two caufes, either of which has hitherto been 
fcarce coniidered as conducing thereto; the one an 
emphyfema, and the other a varicofe aftedion of the 
pulmonary vein. Had the caufes of this difeafe been 
as perfedly known during the life of the patient, as 
fince his death, the cafe would not have admitted of 
a cm e ; as there was no method of difcharging the 
extravafate air from the lungs; neither could any 
medical procefs alter or amend the varicofe hate of 
the pulmonary vein. 
' Such a hate of lungs, as that juh now defcribed, 
in an otherwife healthy young man, could not, I was 
perfuaded, happen but from fome very powerful 
caufe; and, upon enquiry, I was informed, that about 
the beginning of Odober, not two months before his 
death, from fomething which had greatly offended
