could deferve the name of even the moft imperfedl 
one. I know very well that the lungs are fubjedt 
to many defedlsj and that there are often found in 
them tumours, calloufnefTes, adhefions, ftones, ulcers, 
worms, tubercles, waftings, and the like j but none 
of thefe caufes could hardly have made the fame 
vifcus lofe every fign of its former ftate. The young 
woman being deficient in this lobe, it is furprifing 
how the other can have performed its office in main- 
taining life, and have appeared upon examination 
of the common and natural fize, and its veffels not 
at all dilated by the quantity of blood which they 
received. And as nature has made nothing in vain, 
we cannot but'be aftoniffied to find that fingle which 
ought to be double, as if a man was to have one kid- 
ney inftead of twoj much more wonderful is it 
that, in fo delicate and important an adtion as refpi- 
ration is, one lobe only of the ufual fize and flrudlure 
fhould have performed the fundtions of both. I 
know very well that thofe, whofe misfortune it has 
been to have part of their lungs only flightly difor- 
dered, mufi: have the other confiderably affedted j but 
befides that there may have been occafionally relief 
given, they cannot for a long time have fupported the 
want of a lobe, without giving vilible figns of fo great 
a defedl. In this cafe we have reafon to believe that 
this young woman was born with this monflrous de- 
ticiencyj what is ftrange is, that (he ffiould have 
come to her full growth with it, and have been ap- 
parently healthy, except the convulfive coughs and 
ihortnefs of breath. Thefe are phaDnomena, which 
might be accounted for from obftrudbions in the lower
