this it doth by exaggeration of black Melancholy: or it will make people lunatick andmclancholick if they do but hold it in their mouths: and by its drawing out ot ironPhysitians think it will help well to draw an Artow-head out of ones body.

But we ue the Loadstone b making Glass. Pliny. After Glass was found our,as it is a very cunning invention,men were not content to mingle Nitrejbut they be-gan to add the Loadstone thereunto, because it is supposed, that it will attract the li-quor of the Glals into it self, and into iron also. Hence it is, that in making Glasswe add a little piece of Loadstone to it, for that singular vertue is confirmed by ©urtimes , as well as former times : it is thought so to attract into it self the liquor ofthe Glass, as it draws iron to it; and being attracted, it purgeth it; and from greenor yellowish Glass, it makes it white : but the fire afterwards consumes the Load-stone. Out of Agricola. We read also, That a Loadstone laid to ones head, willtake away all the pains. Galen faith, It hath purging faculties 5 and therefore it isgiven to drink fortheDropsieran l it will draw forth all the water in the Belly. Lastly,I shall not pass by the error of Hadrian, concerning the Loadstone: for he faith, Thatthe iron by its weight makes the Loadstone never the heavier. For the Naturalistsreport,That isa great Loadstone were weighed in a Scale: and after that,should drawiron to it, it would be no heavier then it was when it was alone, though they beboth together ; so the weight of the iron is as it were consumed by the Loadstone,and hindred by it from any effect or motion : which I finde to be false. It is like thatjear in Aristophanes, of a Clown that rid upon an Ass, and carried his Coulter at hisback, that he might not load the Ass too much.
