CLASS I. i. 3. 10. OF IRRITATION. 35 



confifting of two drams of turpentine diflblved by yolk of egg, 

 and fixty drops of tincture of opium, mould be uied at n : 

 and repeated, with cathartic medicines interpofed, every ni 

 or alternate nights. Aerated folution of alkali fh; '.iken 



..rally, and balfam of .copaiva, three or four times a day. 

 Sonic of thefe patients recover after having made no water for 

 jiine or ten days. 



If a ftone (licks in the ureter with incefiant vomiting ten gr 

 of calomel mult be given in fmall pills as above ; and feme b 

 afterwards infufion of fenna and ialts and oil, if it can b? made 

 to itay on the (loinadi. And after : has operated four 



.or five times, an opiate is to be given, if the pain continues, con- 

 fiiling of two grains of opium. If this does not fucceed, tf. 

 twenty electric (hocks through the kidney fhould be tried, and 

 the purgative repeated, and afterwards the opiate. The patient 

 ihoiild be frequently put into the warm bath for an hour at a 

 time. Eighty or a hundred dfops of laudanum given in a .. 

 ter, with two drams of turpentine, are to be preferred to the 

 two grains given by the flomach as abovej when the pain and 

 vomiting are very urgent. 



jo. Calculus veficz. Stone of the bladder. The nucleus, or 

 kernel, of thefe concretions is always formed in the kidney, as 

 above defcribed ; and paflin^ clown the ureter into the bladder, 

 is there perpetually increaled by the mucus and falts fecreted 

 from the arterial fyftem, or by the mucus of the bladder, difpo- 

 fed in concentric ftrata. The (lories found in the bowels of 

 liorfes are alfo formed on a nucleus, and coniiil of conce. 

 fpheres ; as appears in fawing them through the middle. Bi^t 

 as thefe are formed by the indurated mucus of the in.teftines 

 alone without the urinary falts, it is probable a difference \yould 

 be found on their analyfis. 



As the (tones of the bladder are of various degrees of hardnefs, 

 and probably differ from each other in the proportions at lead of 

 their component parts ; when a patient, who labours under this 

 afflicling difeafe, voids any fmall bits of gravel ; thefe mould be 

 kept in warm folutions of caudle alkali, or of mild alkali well 

 aerated ; and if they diffolve in thefe folutions, it would afford 

 greater hopes, that that which remains in the bladder, might be 

 affected by thefe medicines taken by the (lomach, or inj' 

 into the bladder. 



To prevent the increafe of a ftone in th* bladder much diluent 

 drink (hould be taken ; as half a pint of water warmed to about 

 eighty degrees, three or four times a day : which will r;.ct only 

 prevent the growth of it, by preventing any mi . : falts 



from being precipitated from the urine, and by keeping the mu-
