 that the dry and barren rocks repeat, by their 

 echos, the murmuring found of the waters and of 

 the forefts ; and that the plane furfaçes of the wa- 

 ters, which have neither forefts nor hiils, reprefent 

 their colours and forms by reflecting them.

 is mitigated in all the places where it would have 

 been hurtful. Firft, the Sun is five or fix days 

 longer in our northern Hemifphere, becaufe that 

 Hemifphere contains the greateft part of the Con- 

 tinents, and is the moft: inhabited. His difk ap-

 which, added to it's twilights, confiderably in-

 that it is, the farther does the refraction of his rays 

 extend. This is the reafon that it is greater in 

 the morning than in the evening, in Winter than 

 in Summer, and at the beginning of Spring than
