XI. At length being sufficiently persuaded, that the experiment succeeded 

 very well with oak shavings, M. Neuman wished to try the least quantity of 

 the infusion of oak requisite to produce some degree of the blue tincture; he 

 tried several quantities, from ^ drachm to 20, 15 drops and downwards; so 

 that one single drop, with a drop at least of the solution of the mineral earth 

 of iron, was sufficient to impregnate the whole half ounce of malt spirits, and 

 to produce a blue tincture, though not so greatly saturated. 



Of a Fork put up the Anus, and aflenuards extracted through the Buttock. 

 Communicated by Mr. Rob. Payne, Surgeon at Lowestoff. N° 39I, p. 408. 



James Bishop, an apprentice to a ship-carpenter in Great Yarmouth, about 

 19 years of age, had violent pains in the lower part of the abdomen, for 6 or 

 7 months; it did not appear to be any species of the colic; he sometimes made 

 bloody urine, which induced Mr. P. to believe it might be a stone in the bladder. 

 He was very little relieved by physic ; at length a hard tumour appeared in 

 the left buttock, on or near the glutasus maximus, 2 or 3 inches from the 

 verge of the anus, a little sloping upwards. A short time after he voided pu- 

 rulent matter by the anus, every day for some time. The tumour at length 

 broke, and shortly after the prongs of a fork appeared through the orifice of 

 the sore, above 4- inch beyond the skin, on which his violent pains ceased. 

 Mr. Payne divided the flesh between the prongs, and made a circular incision 

 about the prongs; then with a strong pair of pincers extracted it, not without 

 great difficulty, handle and all entire. The end of the handle was besmeared 

 with the excrement, when drawn out. It was 6^ inches long, a large pocket- 

 fork; the handle ivory, but died of a very dark brown colour; the iron part is 

 very black and smooth, but not rusty. The patient's account of the matter 

 was, that being costive, he put the fork up his fundament, thinking by that 

 means to help himself, but unfortunately it slipped up so far, that he could 

 not recover it again. 



He further says, he had no trouble or pain, till a month, or more, after 

 it was put up. 



Tivo Cases of bisects voided by the Urinary Passage. By Dr. Daniel Turner, 

 Coll. Med. Loud. Lie. N°391, p. 4 JO. 



Nov. 24, l/^S, a poor woman came to crave Dr. T.'s advice for a child 

 about 16 months old, bringing with her a worm, which she said the apothecary 

 had just then drawn out of the child's penis, who had for several days before 

 laboured under great uneasiness, which she called convulsions of the bowels.
