Its Back or Outfide was convex, agreeable to the 
concave Surface of the Ribs, which had made In- 
dentations on that part of it where they prefs’d ; Its 
Infide was concave as the Ribs ; the right Lobe of

“ Since Mr. Giffard has not inferred the Particulars

“ was troubl’d for fome Years with a ftiort Cough, 
“ which latterly was accompanied with a difficulty 
of Breathing, and great Labour in Infpiration ; and

“ more, brought on the Peripneumonia, of which he 
“ died in a few Days. The Rife and Succeffion of 
thofe different Symptoms proceed fo naturally 
“ from the Formation and Growth of this prseterna- 
“ rural Body, as well as the particular part of the 
“ Thorax where it was lodg’d, that it is entirely nced- 
“ lefs to fay any thing more upon them.
