Part III. Of Tin, Lead, and Iron. 535 
actions, (a) Some of the ways of giving a due Temper to ^Num. 
Iron? according to the ufe made of it, are fet down by 137- 
Ambrofinus. (b) For one Temper is requir d for drawing it ^^mli 
into Wyre 5 another, for a File 3 another, for a Chifel 3 ano- 
ther, for d.Sword' 0 another, for the Edge of a Sword in par- 
ticular, and the like. For the hardening of Iron for 
Files 3 one of the Kings Farriers, upon my enquiry, cohi- 
mendeth this following way. 
Take Horfe Hoofs or Rams Horns , and hang them over 
the fire till they drop like Glew. Take alfo pieces of Leather, 
and burn them black. Powder them both, and put to 
them ftale Vrine, and Bay-Salt. Let them ftand together $ 
the longer the better : at three or feven years end it will be 
excellent. Cafe the Iron with this Mixture, and give it a 
ftrong heat, fufficient to fufe the Mixture, for three hours $ 
and then cool it. The furface of this Iron will be as hard 
as the hardeft Steel, and will make excellent Files : but the 
hardening reaches not to the heart of the Iron. 
Of Rufma (a brown and light Iron fubftance) with \ as 
much Quicks Lime fteeped together in Water, the Turkjjh 
Women make their Pfilothron, to take off their Hair where- 
fover they pleafe. There are many Medicinal Preparations 
of Iron or Steel: But none, that I know of, equal to the 
TinSlure made without Acids 3 efpecially in Obftruclions, 
and to ftrengthen the Tone of the parts,as in Lienterick, and 
other like Cafes. Againft all outward and inward Hemor- 
rhages, Quercetan highly extols his Oleum Mart it. A Tinffure 
of Steel made with White Wine, faith Ambrofinus, (c) is a S f A ^J 6 ^ 
ftrong Cathartick. What he means, I know not. Perhaps 
he might find fome fuch effedt upon himfelf, from that, as 
one I know in this City, doth from Mithridate, which com- 
monly gives him a Stool extraordinary. And another,upon 
whom Marmalad hath the like effed.
