Part III. Of Sutyhurs. 
The Alum-Stone (of a blackifh colour, and flaky, like Cornijh 
Slate ) is found in moil of the Hills between Scarbrough 
and the River of Tees in TorkcJhire. As alfo near Pre/ion in 
Lancajhire. Of thefe Stones calcin'd, is made a Lee 3 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 call'd Slam, being predominant 3 to precipitate 
the fame, they add the Lees of Kelp 3 made of Tangle, a 
Sea- Weed commonly among Oyflers. 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 s 
will moulder in pieces, and yield a Liquor whereof Copperas 
may be made. 
Fallopiuds Aq. Aluminis Magiflralis, is of good ufe againft 
ulitoward V leers. Deyers boil their Cloaths,ot Tarn in 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 walh the Skins 
of Beafts or Fowls herewith on both fides, or perhaps on 
the Feathers, only ftrewing Alum in fine powder, would be 
a good way to keep them from the Mctf />,and growing dank 
in moift Weather, and fo to preferve them for ever.
