But we may not only improve the notes of bkds 
by a happy mixture, or introduce thofe which were 
never before heard in Great-Britain ; as we may alfo 
improve the inttrument with which the paflages are 
executed. 
If, for example, any bird-fancier is particularly 
fond of what is called the fong of the Canary bird, 
which however muft be admitted to be inferior in 
tone to the linnet, it would anfwer well to any fuch 
perfon, if a nettling linnet was brought up under a 
Canary bird, becaufe the notes would be the fame, 
but the inttrument which executes them would be 
improved. 
We learn alfo, from thefe experiments, that nothing 
is to be expe&ed from a nettling brought up by hand, 
if he does not receive the proper inftruvttion from the 
parent cock : much trouble and fome coft is there- 
fore thrown away by many perfons in endeavour- 
ing to rear nettling nightingales, which, when they 
are brought up and fed at a very conttderable ex- 
pence, have no fong which is worth attending to. 
If a woodlark, or fkylark, was educated, however, 
under a nightingale, it follows that this charge (which 
amounts to a lhilling per week *) might be in a great 
mealure faved, as well as the trouble of chopping 
frefh meat every day. 
A nightingale, again, when kept in a cage, does 
not live often more than a year or two j nor does he 
ling more than three or four months ; whereas the 
■' .Olina fpeaks of a pafte which is ufcd in Italy for nightin- 
gales ; but I cannot find that it ever anfwers with us ; perhaps, 
they bring their nightingales up by hand, and fo accuftom 
•them from their earlieft infancy to fuch food.
