aft ions, (a) Some of the ways of giving a due Temper to ^ Num> 
Iron, according to the ufe made of it, are let down by 137. 
Ambrofinus. (b) For one Temper is requir d for drawing it M uf. Metaiil 
into Wy re $ another, for a File 5 another, fotzChifel 5 ano- 
ther, for a Sword 5 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, com- 
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 (land together 5 
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 5 
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 Quick 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 
Tintture made without Acids $ efpecially in Obstructions, 
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 Martk. A Tinfture 
of Steel made with White Wine, faith Ambrofinus, (c) is a S f A $k°* 
ftrong Cat bar tick What he means, I know not. Perhaps 
he might find fome fuch effect 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 effect,
