solved and confounded with the mass of matter that composed the tumour, 

 which was equally protuberant within the thorax, and composed of the same 

 materials. Part of the 5th and 7th ribs were dissolved in the same manner, 

 into a kind of substance between bone and cartilage, with a thick, coat of 

 steatomatous matter. 



Within the cavity of the thorax were 37 of these diseased bodies, most of 

 them attached either to the vertebrae or the ribs ; and wherever they were at- 

 tached, the cortex of the bone was destroyed, and its internal cellular part 

 filled with the diseased matter. 



Immediately above the diaphragm was a large scirrhous body, lying across 

 the spine and the aorta, the latter of which lay in a sinus formed in its lower 

 part ; it had no attachment to any other part, and weighed IS-J- oz ; and from 

 its situation, must have taken its rise from some of the lymphatic glands lying 

 about the thoracic duct. 



From the origin of the aorta, from the heart, quite up to the basis of the 

 cranium, all the blood-vessels were surrounded with these scirrhous bodies, and 

 the thyroid gland was diseased in like manner, and bony within. On the left 

 side was another of these bodies, made out of the glandula renalis, weigh- 

 ing 94- oz. 



On the right, the glandula renalis was in a natural state ; but the cellular 

 membrane, which surrounds the kidney, was filled with a large cluster of these 

 bodies of different sizes, some of them entirely suetty, others intermixed with 

 bony particles : three or four of them were attached to the body of the kidney, 

 and these were a sort of cartilage, beginning to ossify. 



The pancreas was quite scirrhous, and very large. One very large tumour 

 sprung from the spongy body of the third vertebra of the loins, the bony texture 

 of which was so dissolved, and mixed with the matter of the tumour, that the 

 knife passed through it with great ease. 



The inner side of the os ilium, all the ischium and pubis, were covered with 

 these appearances ; and on removing them, the bone was found in the same 

 state as the sternum and ribs. The middle of the right os femoris was sur- 

 rounded with a mass of the same matter, and the bone underneath in the same 

 state. 



In the bottom of the orbit, surrounded by the recti muscles, was a pretty 

 large steatoma, which occasioned the protrusion of the eye ; and, by pressing 

 on the optic nerve, probably caused the blindness.
