 climates on the oppofite f|de of the Torrid Zone; 

 nor is there any reafon at all for birds to pafs 

 from the northern to the fouthern hemifphere, 

 in order to arrive at a place of a proper and 

 wifhed*for temperature ; for when a bird leaves 

 its northern fituation at the approach of winter, 

 and advances fouthward, he arrives at fome 

 place of an equal degree of heat \yith that of 

 the northern fummer from whence he departed, 

 without coming near the Equinodlial Line ; fo 

 that I lee no reafon at all to fuppcfe they pafs 

 from the north, acrofs the Line, to fouthern ha,- 

 bitations v but I think it moft reafonable that 

 they fliould ftop when they have found a reft- 

 ing place in a climate of equal temperature with 

 that from which they departed -, for to fuppofe
