Class I. 2. 3. li. OF IRRITATION. 97 



it is, that they chiefly drink the water of the Derwent, which 

 arifes in a mountainous country, and is very frequently blacken- 

 ed as it pafles through- the rriorailes near its fouice ; and is gen- 

 erally of a darker colour, and attended with a whiter foam, than 

 the Trent, into which it falls j the greater quantity and white- 

 nefs of its froth I fuppofe may be owing to the vifcidity com- 

 municated to it by the colouring matter. The lower parts of 

 the town of Derby might be eafily fupplied with fpring water 

 from St. Alkmoncfs well ; or the whole of it from the abun- 

 dant iprings near Bowbridge : the water from which might be 

 conveyed to the town in hollow bricks, or clay-pipes, at no very 

 great expence, and might be received into frequent refervoirs 

 with pumps to them ; or laid into the houfes. 



M. M. Twenty grains of burnt fponge with ten of nitre mads 

 with mucilage into lozenges, and permitted to dilTolve flowly un- 

 der the tongue twice a day, is alTerted to cure in a few months ; 

 perhaps other animal charcoal, as candle-fnuffs, might do the 

 fame. 



I have directed in the early flate of this difeafe a mixture of 

 common fait and water to be held in the mouth, particularly 

 under the tongue, for a few minutes, four or lix times a day for 

 many weeks, which has fometimes fucceeded, the fait and water 

 is then fpit out again, or in part fwallowed. Externally vinegar 

 of fquills has been applied, or a mercurial plafter, or fomentations 

 of acetated ammoniac ; or ether. Some empyrics have applied 

 cauftics on the bronchocele, and fometimes, I have been told, 

 with fuccefs y which fhould certainly be ufed where there is 

 danger of fufFocation from the bulk of it. One cafe I faw, and 

 one I was well informed of, where the bronchocele was cured by 

 burnt fponge, and a hedlic fever fupervened with colliquative 

 fweats ; but I do not know the final event of either of them. 



De Kaen affirms the cure of branchocele to be effected by 

 fiowers of zinc, calcined egg-fhells, and fcarkt-cioth burnt to- 

 gether in a clofe crucible, which was tried with fuccefs, as he 

 afiured me, by a late lamented phyfician, my friend, Dr. Small 

 of Birmingham ; who to the cultivation of modern feiences add- 

 ed the integrity of ancient manners ; who in clearnefs of head, 

 and benevolence of heart, had few equals, perhaps no fuperiors. 



21. Scrofula. King's evil is known by tumours of the lym- 

 phatic glands, particularly of the neck. The upper lip, and di- 

 vifion oi the noftrils are fwelled, with a florid countenance, a 

 fmooth ftin, and a tumid abdomen. Cullem The abforbed flu- 

 ids in their courfe to the veins in the fcrofuia are arrefted in the 

 lymphatic or conglobate glands ; which fwell, and after a grean 

 length of time, inflame and fupptirate. Materials of a peculiar
