had may in part adhere to the fides of the bottle, and become 

 difiblved >n the acid of the wine or cyder. Milk kept in lead is 

 highly pernicious, as in the in fiance above related. Nor {hould 

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

 is frequently done ; nor fhould fleth-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 veil el* 

 tinne;l within. Now the lining of thefe vefTels confifts, I am 

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

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

 much on foupb long boiled, as the French, ars perpetually fub- 

 jecl to complaints of the ilomach and intettines. When a 

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

 it, it becomes black 5 which is owing to the lead, which is mix- 

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

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

 bafon. 



In an ingenious pamphlet lately publifhed by Mr. Clutterbuck, 

 feveral cafes are given of the fuccefsfui ufe of mercury in tha 

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

 In fome of thefe patients a drachm of ilrong mercurial ointment 

 was rubbed morning arid night on the wrifts, till the mouth be- 

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

 ricini ; and mothers a quarter of a grain ofhydragyrum muria- 

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

 great apparent advantage. The author ingeniouily aflcs, if 

 imall doles of fome preparation of lead might not be given inter- 

 nally to counteract: the ill effects fometimes believed to refult 

 from the too long ufe of mercury. On the Poiibn of Lead,

The effecl: of metals in deftroying or preventing the acidity 

 of 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 veffel, this does not occur ; as the acid is attracted by the 

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

 ton, to have the fame effedl in preferving the colour of fyrup 

 of violets.
