But it may be faid, that there hath been a 

 Farinelli, and a Manzoli, whole voices were fo

To this I again anfwer, that the catalogue of 

 fuch names would be a very fhort one ; and that 

 we attribute thofe effects to caftration, which fhould 

 rather be afcribed to the education of thefe fing- 

 ers. 



Caftration commonly leaves the human voice at 

 the fame pitch as when the operation is performed; 

 but the eunuch, from that time, is educated with 

 a view only to his future appearance on the opera 

 ftage; he therefore manages his voice to greater 

 advantage, than thole who have not fo early and 

 conftant inftruction. 



Confidering the fize of many ringing birds, it 

 is rather amazing at what a diftance their notes may 

 be heard. 



I think I may venture to fay, that a nightin- 

 gale may be very clearly diftinguifhed at more than 

 half a mile*, if the evening is calm. I have alfo 

 obferved the breath of a robin (which exerted itfelf ) 

 fo condenfed in a frofty morning, as to be very 

 vifible. . 



* Monf. de Buffon fays, that the quadruped which he terms 

 the buarine, may be heard at the diitance of a league. Ornith.
