arm appeared to have a sort of firmness, that the muscles alone were incapable of 

 giving it; and on the 30th of the same month it had acquired a degree of 

 solidity, which was nearly equal to the hardness of bone; for it was strong 

 enough to support itself, and yielded very little to the pressure that was made 

 upon it; but the patient was still unable to make any use of it, till the 55th day 

 after the operation, at which time he began to move it a little. It was scarcely 

 possible that so remarkable a case should not be attended with some accidents, in 

 the course of the cure; so that, on the l6th of June, he was not at all 

 surprised at the appearance of a pustule on the upper part of the scar, from which 

 there was an oozing of matter. On the next day he passed a probe into this 

 opening, which entered with some difficulty the length of an inch; but he did 

 not find any splinters of bone, which he expected to meet with. June 18, he 

 made a large opening in this part, and extracted a point of bone, which seemed 

 to have shot out in a very particular manner towards this pustule, and might 

 probably have contributed, by its irritation, to have produced this fistula. June 

 IQ, he took away the remains of this bony substance, situated underneath the 

 above fistula, and which was but slightly attached to the neighbouring soft 

 parts; after which the cure of this wound was completed in 1 5 days. 



On the 25th of July, the lOOth day after the operation, he perceived another 

 pustule breaking out near the lower part of the scar. He then began to suspect, 

 as there had been a flow of matter from the arm for several years, that the con- 

 stitution had acquired a habit of discharging itself at this part; and attributed to 

 that cause these trifling relapses, as well as the former more considerable one, 

 which the patient had suffered. From whatever spring these habitual discharges 

 may be derived, and whatever may be the reasons assigned for the relapses they 

 produce, it is well known that they are sometimes diverted or cured by issues; 

 he therefore ordered a large caustic to be applied to the patient's left leg. The 

 arm was at this time very solid to the touch, but still yielded a little to its own 

 weight, as the branch of a tree, or a piece of green wood ; he therefore had a 

 bracelet of whalebone made to support and keep it steady. August 1st, the 

 pustule, which he had perceived on the 25th of July, appeared to be much in- 

 creased in size, and was spread out into fungous flesh : he passed a probe into it, 

 and found some pieces of bone bare towards its upper part. August 10, a small 

 scale was exfoliated, and from that time the fungous flesh began to disappear. 



In Sept., 5 months after the operation, the issue afforded a very plentiful dis- 

 charge, and had attracted the humour so powerfully towards this part, that the 

 kg on which the caustic had been applied, appeared swelled and grew painful ; 

 but at the same time, the arm was entirely cured; having recovered all its 

 actions and uses, together with its proper form and length. And on the 12th 

 of October, Romain was discharged from the hospital, very thankful for the re-
