[84] PAGE 28, LINE 23. Page 28, line 20. _quem nos verticitatem dicimus._--See the notes on Gilbert's glossary, _ante_. The word verticity remained in the language. On p. 140 of Joseph Glanvill's _Vanity of Dogmatizing_ (Lond., 1661) we read: "We believe the _verticity_ of the _Needle_, without a Certificate from the _dayes_ of _old_."
[85] PAGE 29, LINE 15. Page 29, line 16. _Nos verò diligentiùs omnia experientes._--The method of carefully trying everything, instead of accepting statements on authority, is characteristic of Gilbert's work. The large asterisks affixed to Chapters IX. X. XI. XII. and XIII. of Book I. indicate that Gilbert considered them to announce important original magnetical discoveries. The electrical discoveries of Book II., Chapter II., are similarly distinguished. A rich crop of new magnetical experiments, marked with marginal asterisks, large and small, is to be found in Book II., from Chapter XV. to Chapter XXXIV.; while a third series of experimental magnetical discoveries extends throughout Book III.

"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."

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_."
