bird-catchers call rubbijh , or no particular note 
whatfoever. 
I hung this robin nearer to the nightingale than 
to any other bird; from which fiiffc experiment I 
conceived, that the fcholar would imitate the mafter 
which was at the lead didance from him. 
From feveral other experiments, however, which 
I haveiince tried, I find it to be very uncertain what 
notes the nedling will mod attend to, and often 
their long is a mixture ; as in the indance which 1 
before dated of the fparrow. 
I mud own alfo, that I conceived, from the ex- 
periment of educating the robin under a nightin- 
gale, that the fcholar would fix upon the note which 
it drd heard when taken from the ned ; I imagined 
likewifc, that, if the nightingale had been fully in 
long, the indr.udtion for a fortnight would have been 
furacient. 
I have, however, fince tried the following ex- 
periment, which convinces me, fo much depends 
upon circumdances, and perhaps caprice in the fcho- 
lar, that no general inference, or rule, can be laid 
down with regard to either of thefe fuppofitions. 
I educated a nedling robin under a woodlark-lin- 
net, which was full in fong, and hung very near to 
him for a month together.: after which, the robin was 
removed to another houfe, where he could only 
hear a fkylark-linnet. The confequence was that 
the nedling did not fing a note of woodlark 
{though I afterwards hung him again juft above the 
wood-lark-linnet} but adhered entirely to the fong 
of the fkylark-linnet.
