Iron and Magneticks
Chapter 2
The Directive or Versorial Virtue (which we call verticity): what it is, how it exists in the loadstone; and in what way it is acquired when innate →
Chapter 3
How Iron acquires Verticity through a Loadstone, and how that verticity is lost and changed →
Chapter 4
Why Iron touched by a Loadstone acquires an opposite verticity →
Chapter 5
The Touching of pieces of Iron of divers shapes →
Chapters 7-8
A determined Verticity and a disponent Faculty are what arrange magneticks, not a force, attracting or pulling them together, nor merely strongish coition or unition. →
Chapters 9
Figures illustrating direction and showing varieties of rotations →
Chapters 10-11
Mutation of Verticity and of Magnetick Properties, or on alteration in the power excited by a loadstone →
Chapters 12
In what way Verticity exists in any Iron that has been smelted though not excited by a lodestone →
Chapters 13
Why no other Body, excepting a magnetick, is imbued with verticity by being rubbed on a loadstone; and why no body is able to instil and excite that virtue, unless it be a magnetick →
Chapter 15
The Poles, Æquator, Centre in an entire Loadstone remain and continue steady; by diminution and separation of some part they vary and acquire other positions →
Chapter 17
The Use and Excellence of Versoria: and how iron versoria used as pointers in sun-dials, and the fine needles of the mariners' compass, are to be rubbed, that they may acquire stronger verticity →
