kidney was the smaller stone, which had so entered the ureter with its conical 

 part, as adequately to stop it, like a cork in a bottle. When we had removed 

 this stone, though we found no other in the ureter, we could not force any water 

 through it into the bladder, though a strong injecting syringe was used : for the 

 ureter was greatly contracted, and there seemed an absolute coalescence of its sides. 

 It is certain that the canals of a human body, which cease to have any 

 fluid transmitted through them, soon coalesce ; as is particularly evident in the 

 canalis arteriosus, urachus, umbilical vessels : nay we see the external coats of 

 the intestines soon grow together, if they are not constantly lubricated with their 

 proper oily mucus that prevents it. This will be much sooner effected in the 

 ureters, if they happen to be excoriated by small stones, or gravel : for we find 

 «ven the fingers, or other excoriated parts, soon grow together, unless prevented 

 by due care. Doubtless this is sometimes the case in fatal ischuries ; though 

 more frequently they arise from obstructing gravel, stones, grumous blood, 

 tough mucosity, or the like. 



Of the extraordinary Effects of Mush in Convulsive Disorders. By J. Wall,* 



M.D. N°474, p. 213. 



[Dr. Wall in this communication gives an account of the beneficial employ- 

 ment of musk in certain convulsive disorders ; but as this paper is reprinted in 

 this author's works, with which every physician is now well acquainted, it is 

 deemed unnecessary to retain it in these collections. Dr. W. prescribed the musk 

 in doses of 10 or 12 grs. to adults, in the form of a bolus, where it could be 

 given by the mouth, and when not in that way, he administered it by clysters.] 



^ Letter from Andrew Reid, Esq. to Dr. Wilmoty concerning the Effects of the 

 Tonquinese Medicine. Dated London, Nov. 5, 1745.-|- N° 474, p. 225. 



About 15 years antecedent to the above date, Mr. R. learned in China, that 

 the Tonquinese had an infallible cure for the bite of a mad dog, and, being very 

 desirous of possessing so valuable a receipt, he was 2 or 3 years after, favoured 

 with it by the late Mr. Hart. 



They take of the best musk about l6 grs.; of the purest native cinnabar, and 

 finest Vermillion, each about 24 grs. ; and, having reduced them separately to 

 impalpable powders, mix and administer them in about a gill of arrack; which, 

 in 2 or 3 hours, generally throws the patient into a sound sleep, and perspira- 

 tion ; if not, they repeat the dose, and think the cure certain. 



• Of this ingenious physician some authentic particulars will be given in the following (viz. the 

 44th) vol. of the Philos. Trans. 



+ Dr. Edward Wilmot remarks, that these experiments of Mr. Reid probably gave occasion to the' 

 liberal use of musk at the above period. — Orig.
