 I imagined likewife, that, if the nightingale had 

 been fully in fong, the inftruclion for a fortnight 

 would have been fufficient. 



I have, however, fince tried the following expe-

 was, that the nettling did not fing a note of wood-

 bove the woodlark-linnet) but adhered entirely to 

 the fong of the fkylark-linnet. 



Having thus ftated the refult of feveral experi-
