under the 3d, 4th, 5th and 6th ribs, closely and strongly connected to the 

 periosteum of the ribs, and the tunica propria of the inner intercostal muscles, 

 by fibres which shot from a strong and thick intervening membrane, which 

 closely adhered to its outer surface or back, and was continued over its inner 

 likewise, thereby forming a capsula for this preternatural substance. Its upper 

 edge lay immediately below, and was contiguous to that part of the ribs, where 

 they become cartilaginous: the membrane that adhered to, and covered it, con- 

 tinued thick some distance from it, and gradually grew thinner, and was at 

 length lost in the pleura ; so that this extraneous body seemed to have been 

 formed between the two lamellae of that membrane. The lungs so strongly 

 adhered to its inside, that on separating them, part remained to it : on cutting 

 into which, the cells were stufted with a thin, but somewhat digested pus. 



On the same side, towards the back, was another substance, but perfectly 

 bone, invested as the former, with a strong and thick membrane, and by the 

 fibres which shot from it, tied to the body of the vertebrae, and the 4th, 5th, 

 6th, and 7th ribs, and intercostal muscles. Its back or outside was convex, 

 according to the concave surface of the ribs, which had made indentations on 

 that part of it where they pressed: its inside was concave as the ribs; the right 

 lobe of the lungs strongly adhered; part of which for that reason remained to 

 it after separation: its length was about 7 inches; breadth about 3, from edge 

 to edge; its thickness, in some parts i, in others ^ of an inch. It had, as 

 the former, a thick membrane running from it, which gradually thinning was 

 at length lost in the pleura; from whence Mr. G. judged this extraneous sub- 

 stance to have been formed as the forementioned. 



" Since Mr. GifFard has not inserted the particulars of this gentleman's indis- 

 position. Dr. Rutty adds, that on inquiry, he has since been informed, that 

 the patient was troubled for some years with a short cough, which latterly was 

 accompanied with a difficulty of breathing, and great labour in inspiration; and 

 some time after, with a weight and pain on the right side; which symptoms 

 increasing more and more, brought on the peripneumonia, of which he died 

 in a few days. The rise and succession of those difl^erent symptoms proceed so 

 naturally from the formation and growth of this preternatural body, as well as 

 the particular part of the thorax where it was lodged, that it is entirely needless 

 to say any thing more upon them.
