ordinarily being of a rare body that doth not fliew it felf unto 

 LS (namely, theaire) is for the molt pare unknown by us. But 

 bee a ulc nothing can make imprcffion upon our mind, andcaufe 

 us to oivc it a nameotherwile then by being known : therefore 

 our underftanding to make a complete notion, muft adde fome- 

 thint? elfe to this fleering and unremarkable luperScies that may 

 bring it unto our acquaintance. And for this end we may con- 

 fidcr further, that as this fuperficies hath in it fe'f, k> the body 

 cnclofed in it gnineth a certain determinate refp \^ unto the fta- 

 ble and immoveable bodies that environ it. As for example, we 

 underftand fuch a tree to be in Inch a place by having r^ch and 

 fuch refpe&s to fuch a hill near it, or to fi'ch a hou'e chat fiand- 

 eth by it, or to fuch a river that runneth under ic, or to f -ch an, 

 immoveable point of the heaven that from the funncs riling ia 

 the equinox is called Euft, and fuch like. To which urpoie, it 

 impoitech not whether thefc that we call immovtobie bodies 

 and points be truly fo, or do but feem fo to mankind. For man 

 talking of things according to the notions heframeth of them 

 in his mind ( ibeecii being nothing elfe but an exprellion co an 

 other man, of the images he hath within himfelfj and his noti- 

 ons being made according to the feeming of the things, he rnuft 

 needs make the fame notions, whether the thing? be truly fo in 

 themfelves, or but teem to be fo, when that feeming or appea- 

 rance is alwayes conftantly the fame. 



Now then when one body dividing another, getteth a new

 faying, it hath ch-inged its place, and is now no longer where ic 

 xvas at the firft. And this change of place we call Loc^lt moti- 

 on: to wit, the departing of a body from that hollow fuperficies 

 which incloled it ; and its changing unto an other , whereby it 

 gaineth new refpe&s to thofc parts of the world that have, or

 So as rence it is evident that the fubft ince of locall motion con-
