Part III. Of Sulphurs. 
The Alum-Stone (of a blackifh colour, and flaky, like Cornijh 
Slate ) is found in moft of the Hills between Scarbmigh 
and the River of Tees in TorkzJhire. As alfo near P reft on in 
-Lancashire. Of thefe Stones calcin'd, is made a Lee $ and 
of the Lee, Alum. The Lee after the firft (hooting of the 
Alum 3 is called Mothers. In which, certain Nitrous and 
other parts calfd Slam, being predominant $ to precipitate 
the fame, they add the Lees of Kelp 5 made of Tangle, a 
Sea- W eed commonly among Oyfters. And then, a certain 
proportion of Vrine, both for the fame purpofe, and to 
keep the Kelp-Lees from hardening the Alum too much. 
The Mine, before it is calcin d, being expofed to the Air, 
will moulder in pieces, and yield a Liquor whereof Copperas 
may be made. 
Fallopiuss Aq. Aluminis Magi 'fir alvs, is of good life againft 
untoward V leers. Deyers boil their Cloatbs,or Tarn 111 Alum- 
Water, that they may take both a better, and more dura- 
ble colour. It is ufed, likewife, for the making of a Leather 
foft and white, or fit to take a clear colour, which the Tan d, 
will not do. And I little doubt, but that to wafh the Skins 
of Beafts or Fowls herewith on both fides, or perhaps on 
the Feathers, only ftrewmg Alum in fine powder, would be 
a good way to keep them from the Moth,and growing dank 
in moiit Weather, and fo to preferve them for ever.
