Page 32, line 9. _Gartias ab horto._--The passage from Gartias ab Horto runs as follows in the Italian edition of 1616, _Dell' Historia dei Semplici Aromati._... di Don Garzia dall' Horto, Medico Portughese, ... Venezia MDCXVI., p. 208. "Nè meno è questa pietra velenosa, si come molti hanno tenuto; imperoche le genti di queste bande dicono che la Calamita presa per bocca, però in poca {28} quantità, conserva la gioventù. La onde si racconta, che il Re di Zeilan il vecchio' s'haveva fatto fare tutti i vasi, dove si cocevano le vivãde per lui, di Calamita. Et questo lo disse à me colui proprio, che fu à questo officio destinato." [88] PAGE 32, LINE 29. Page 32, line 29. _Plutarchus & C. Ptolemæus._--The garlick myth has already been referred to in the note to p. 1. The originals are Plutarch, _Quæstiones Platonicæ_, lib. vii., cap. 7, § 1; C. Ptolemæus, _Opus Quadripartitum,_ bk. i., cap. 3. The English translation of the latter, by Whalley (London, 1701), p. 10, runs: "For if the _Loadstone_ be _Rubbed_ with _Garlick_, the _Iron will not be drawn by it_." [89] PAGE 32, LINE 32. Page 32, line 33. _Medici nonnulli._--This is apparently a reference to the followers of Rhazes and Paracelsus. The argument of Gilbert as to the inefficacy of powdered loadstones is reproduced more fully by William Barlowe in his _Magneticall Aduertisements_ (1616, p. 7), as follows: "It is the goodnesse of the _Loadstone_ ioyned with a fit forme that will shew great force. For as a very good forme with base substance can doe but very litle, so the substance of the _Loadstone_ bee it neuer so excellent, except it haue some conuenient forme, is not auaileable. For example, an excellent _loadstone_ of a pound waight and of a good fashion, being vsed artificially, may take vp foure pounds of Iron; beate it into small pouder, and it shall bee of no force to take vp one ounce of Iron; yea I am very well assured that halfe an ounce of a Loadstone of good fashion, and of like vertue will take vp more then that pound will doe being beaten into powder. Whence (to adde this by the way) it appeareth manifestly, that it is a great error of those Physitions and Surgeons, which to remedy ruptures, doe prescribe vnto their Patients to take the pouder of a _Loadstone_ inwardly, and the small filing of iron mingled in some plaister outwardly: supposing that herein the _magneticall_ drawing should doe great wonders."
