There are now nearly five years that this gentleman has found himself perfectly cured. Ever since the difficulty[14] of making water has diminished every day; and these eighteen months past he did not need the introducing of a bougie in the neck of the bladder. Such is the first case I was speaking of: the second is somewhat more surprizing. Mr. J. G. a celebrated artist,[15] having contracted a virulent gonorrhœa at _Milan_, was for several months in the hands of a surgeon in that town, and left uncured. From _Milan_ he went to _Spain_, and there was the space of twenty-five years under the hands of all those who had any repute for curing venereal diseases. At first, all sorts of remedies were tried in turn, by every one of them, and at last astringents rashly made use of to stop the running, in order to have a pretence for payment. The running once disappeared for eleven months, but returned, without any apparent cause, more violently than ever; and ever since, till a few years ago, broke out again after indulging too freely in drinking. As the seat of the disease was the _fossa navicularis_, the urine was always pretty free; but all the other cruel symptoms attending gleets were felt. Having laboured twenty-seven years under these complaints, and being left incurable, the patient applied to me. His disease was so inveterate, that I entertained indeed some doubts of his recovery: I however ventured a fair tryal, and, to my great surprize, after he had undergone a regular treatment for eleven weeks, he found himself entirely cured; at least he has perceived, these two years past, no appearance of a relapse, although he has indulged his bottle. And I may boldly assert, that, the running being not possibly stopt by suppuration, the ulcers are certainly healed, when they for a long space of time furnish no matter. I shall conclude with this observation, that, since a radical cure was effected in the two forementioned cases, _there is no gleet incurable: nay, there is none which cannot easily and speedily be cured if properly treated_.
