198 Dr. burnett’s Jc count of 
language of organ-builders, ciphered, by which the tone 
was continued without the preflure of the finger: and 
though neither himfelf nor his elder fon could find out 
O 
what note it was, the child, w r ho was then amufing him- 
felf with drawing on the floor, left that employment, 
and going to the organ immediately laid his hand on 
the note that ciphered^. Mr. crotch thinking this the 
effeffc of chance, the next day purpofely caufed feveral 
notes to cipher, one after the other, all which he in- 
ftantly difcovered : and at laft he weakened the fprings 
of two keys at once, which, by preventing the valves of 
the wind-cheft from doling, occafioned a double cipher, 
both of which he diredly found out. Any child, indeed, 
that is not an idioL, who knows black from white, long 
from fhort, and can pronounce the letters of the alpha- 
bet by which mufical notes are called, may be taught the 
names of the keys of the harpfichord in five minutes'^ ; 
but, in general, five years would not be fufficient, at any 
age, to imprefs the mind of a mufical ftudent with an 
infallible reminifcence of the tones produced by thefe 
keys, when not allowed to look at them. 
(c) This circumftance proves that he exercifed his eye in drawing, after his 
manner, before he was two years and a half old. 
(d) By remarking that the fhort keys, which ferve for flats and fharps, are 
divided into parcels of threes and twos, and that the long key between every 
two fhort keys is always called d, it is extremely eafy from that note to difcover 
the fituation and names of the reft, according to the order of the firfl feven 
letters of the alphabet.
