time has demolifhed, of which you perceive tur- 

 rets, columns, triumphal arches ; but the habitable 

 parts of which are entirely deftroyed. The fage 

 produflions of Nature are not ufelefs and tran- 

 litory, like the works of Men. Every Ifland has

 of their territory may feem to require. Such is 

 that of Teneriff : it's peak is fo high, as to be co- 

 vered with ice a great part of the year. But that 

 ifland contains mountains of no great elevation, 

 which are proportioned to it's bays : that of the 

 mountains which fupport the peak, fwells up amidfl 

 the others in form of a dome, not unlike the dome 

 of the Invalids rifing above the adjacent buildings. 

 I myfelf obferved it with particular attention, and 

 made a drawing of it, on my way to the Ifle of 

 France. The lower mountains are an appertenance 

 to the illand, and the peak to Africa. 



This peak, covered with ice, is fituated diredly 

 oppofite to the entrance of the great fandy defart, 

 called Zara, and contributes, undoubtedly, to re- 

 frefh the fhores and Atmofphere of it, by the ef- 

 fufion of it's fnows, which takes place in the midft
