The draught began to operate very soon, by vomiting and purging him for near 24 hours in the most violent manner. A large quantity of black inky matter was discharged; and an infinite number of worms, almost as small as threads, were voided. These operations were so intense, that his life was despaired of. But he has not only survived them, but experienced a most wonderful change and improvement after them: for his parents assured me in November 1757, when I saw him, that he had daily grown better from the time of his drinking the mixture, both in body and mind. Instead of a skeleton, as he almost was before, he is become fat, and rather corpulent: and his appetite is no longer ravenous, but moderate and common. His body too is become straight and erect. His understanding is at least as much benefited by this peculiar remedy. It cannot be expected, that he should already have attained much knowlege, as he seemed, before he was so wonderfully relieved, to be almost destitute of ideas. But he appeared, when I saw him, to have acquired nearly as much knowlege in four months, as children usually do in four years; and to reason pretty well on those things, which he knew. He is now capable of being employed on many occasions; is often sent a mile or two on errands, which he discharges as carefully, and then returns as safely, as any person. It is farther remarkable, that the boy’s mother, her father, and sister, are frequently infested with worms. Her father, tho’ about 60 years of age, is still much troubled with them: the worms, which he voids, appear flat, and much larger than those, which his children have observed. Her sister is often exceedingly disordered by them. About three months since they threw her into violent convulsions, and for some time deprived her of her senses. But the mother of the boy has been affected in a more extraordinary manner than the rest. About 20 years ago she voided some worms, which forced their way thro’ the pores of the skin, as it is supposed; for they were found in small clusters under her arms. As she was very young then, she does not remember how she was particularly affected; only, that she suffered violent struggles and convulsions. She is still, about five or six times in a year, seized with fainting fits, which usually attack her in bed, and last three or four minutes; but she cannot certainly say, tho’ there is very little reason to doubt, that they are occasioned by worms. _An Account of the same Subject, in a Letter from Mr._ John Gaze, _of_ Walket, _in the County of_ Norfolk, _to Mr._ Wm.
