of which were of the fize of the fmall, or Lucca 
olive, and were diftended with grumous blood. 
Befides thefe, there was a larger cift in the right lobe 
of the lungs, which was filled with deep- coloured 
ichor : this lobe adhered to the pleura in great part 
of its furface. The lungs in general were of a deep 
red colour, and here and there upon their furface be- 
ginning to fphacelate. 
The figure of the human heart is that of a cone, 
divided through its axis; but in this cafe, the hearts 
figure was altered, and was more compreflcd than 
ufual; and its ventricles difiended with grumous 
blood. 
Every other part of the body was in its natural 
fiate. 
From this examination we find that in this infiance 
refpiration was greatly difiurbed, to fay nothing of 
the cift in the right lobe, nor of the adhefion of that 
lobe to the pleura, from two manifeft and potent 
caufes; viz. the varicofe fhte of the pulmonary vein, 
and the emphyfema throughout the whole fubftance 
of the lungs. 
The ‘varices of the pulmonary vein not only re- 
tarded the blood in its pafiage to the left auricle of 
the heart; but, occupying a much larger fpace in the 
lungs than they naturally fliould, they left lefs room 
for the minute ramifications of the bronchia to ex- 
tend themfelves ; and eonfequently a lefs quantity of 
air was taken in at every infpiration than was ne- 
ceflary for the ordinary purpofes of life. 
But the diforder of the lungs from the ‘varices was 
made infinitely worfe by the emphyfema. For by 
theextravafate air pofieffing fo large a portion of the 
lungs, and which the patient could by no means part
