lead may in part adhere to the fides of the bottle, and becomtt 

 difTolved in the acid of the wine or cyder. Milk kept in lead w 

 highly pernicious, as in the inftance above related. Nor fhould 

 coppers for brewing be edged at the top of them with lead, which 

 is frequently done ; nor mould flefli-meat be falted in leaden 

 citterns. Another way by which lead is liable to be taken into 

 the ftomach is by broth, which is boiled in copper veflels 

 tinned within. Now the lining of theft veilels conuils, I am 

 well informed, of nearly half lead mixed with the tin j which is 

 very foluble in hot greafe. From this'caufe thole, who live, 

 much on foups long boiled, as the French, are perpetually fub- 

 jec~t. to complaints of the ftomach and interlines. When u 

 fauce-pan has been new tinned, if the finger be rubbed' hard on 

 it, it becomes black ; which is owing to the lead, which is mix- 

 ed with the tin. Hence the broth for all fick people fhould be 

 boiled but a (liort time, and be immediately put into a china- 

 bafon. 



In an ingenious pamphlet lately publifhed by Mr. Clutterbuck, 

 feveral cafes are given of the fuccefsful ufe of mercury in the 

 conftipation, colic, and paralyfis of the wrifts, produced by lead- 

 in fome of thefe patienrs a drachm of ftrong mercurial ointment 

 was rubbed morning and night on the wriils, till the mouth be- 

 came fore. In others calomel one grain was given daily with ol. 

 ricini ; and in others a quarter of a grain of hydragyrum muria- 

 tum, fublimate of mercury, was given three times a day with. 

 great apparent advantage. The author ingenioufly alks, if 

 fmall dofes of fome preparation of lead might not be given inter- 

 nally- to counteract the ill e&e&s fometimes believed to refult 

 from the too long ufe of mercury. On the Poiion oi Lz?A,

The effect of metals in destroying or preventing the acidity 

 cf wine or cyder, may be nicely obferved in attending to the 

 colour of fyrup of violets ; which, if it ferments, is changed by 

 the acid thus produced from blue to red : but if it be kept in a 

 tin vefiel, this does net occur ; as the acid is attracted by the 

 metal producing an oxyde. ' Other metals are laid by M. Guy- 

 ton, to have the fame efxe<£l in preferving the colour of fyrup 

 of violets. 



M. M. Firft ooium one or two grains, then a cathartic of 

 fenna, jalap, and oil, as foon as the pain is relieved. Oleum 

 ricini. Alum. Oil of almonds. A bliiter on the navel. Warm 

 bath. The ftimulus of the opium, by reitcring to the bowel its 

 natural irritability in this cafe of painful torpor, afiiits the action 

 of the cathartic; A clylter of the fmoke of tobucco pufhed high
