156 PHILOSOPHICAL TRANSACTIONS. [aNNO 1757. 



If this growth of the frontal bone were compared with that of other exostoses, 

 there might this difference be rationally observed ; that other exostoses are sje- 

 nerally attended with ulcerous tumours, which are for the most part cancerous ; 

 and these might commence at any age. He had drawings taken from tliC right 

 hand of a man of 50, which represent risings of the radius and ulna, with the 

 fingers, to a most frightful degree ; and these began but 6 years before, and 

 were attended with foul running ulcers ; and then the bones of the arm and 

 hand on the left side, were beginning to have the same appearances : whereas 

 the frontal bone of the present subject appeared sound, as far as could be judged : 

 nor did there appear the least disposition to ulceration in any part of it. When 

 this is the case, the growth generally begins while the subjects are young. His 

 sensation on every part of these tumours was exactly like that of every other part 

 of his skin, having not the least uneashiess on being handled. This poor man 

 worked at day-labour in the fields till some months before he came to town. 



Perhaps it might not be improper to lay down the dimensions of these tumours, 

 as the case was so extraordinary ; for the size of them was almost incredible. 

 The vertical tumour was about 7 inches /liameter at the basis, where the bony 

 edge was felt, and about 4 inches high from that edge. From that edge, or 

 the basis of the vertical tumour to the bottom of the great tumour, was 10 

 inches ; so that the length of both, from the vertex to the end of the great one, 

 was about 14 inches: and on viewing it, when he turned his side towards you, 

 the whole mass was 8 or 9 inches over all the way ; hard at top, and flabby 

 downwards, hanging in a kind of plaits. From the eye to the opposite outline 

 of the great tumour was inches ; and lower down, from the left corner of his 

 mouth to the opposite outline of the same tumour, 8 inches. The upj^er small 

 tumour over the nose, was 1 4- inch long by 1 and 4 inch ; the middle tumour 

 was 2 inches long from the ala nasi, to which it hung, and of the same breadth ; 

 and the lowest tumour shaped like a goose's egg, was 44- inches long by near 3 

 inches over. 



This man was under the care of Mr. Crane of St. Bartholomew's hospital, who 

 had just then taken off the lowest of these 3 anterior tumours, and also the 

 tumour which hung underneath to the under lid of his right eye. He intended 

 to take off that at the ala nasi next, and so on till he takes away all the smaller 

 tumours first : afterwards the larger would be considered. The substance of 

 those cut off was entirely fat ; nor was there the least speck of blood in the 

 lowest of the 3 smaller tumours : but there was an haemorrhage from a vessel di- 

 vided in taking off that hanging to the right eye-lid ; which soon yielded to the 

 methods he made use of, and went on successfully till quite healed.
