Crossword-Solution: VERTICITY 9 letters, 4 clues 🏆 scrabble score: 17

The old window-stanchions had become magnetic, proving, as he thinks, that iron "acquires verticity" from long lying in one position.

But above all it is most observable, that here are all kind of Colours generated in a _pellucid_ body, where there is properly no such refraction as _Des Cartes_ supposes his _Globules_ to acquire a _verticity_ by: For in the plain and even Plates it is manifest, that the second refraction (according to _Des Cartes_ his Principles in the _fifth Section of the eighth Chapter of his Meteors_) does regulate and restore the supposed _turbinated Globules_ unto their former uniform motion.

The next induction that Gilbert made was that as the magnet possesses verticity and turns towards the poles, so the loadstone-earth possesses a verticity and turns on an axis fixed in direction.[84] He could now discuss the motions of a loadstone in general, in terms of its nature, just as an Aristotelian discussed the motion of the elements in terms of their nature.

Variation and declination he later explained as due to irregularities of the surface of the earth, while direction or verticity is the ordering motion that precedes coition.[124] This leaves only coition and revolution as the basic motions.

Verticity, polar vigour, not [Greek: peridinêsis] but [Greek: peridineisios dunamis]: not a vertex or [Greek: polos] but a turning tendency.
