REV. SI R,

May 26, 17770, 
I RECEI V ED your favour in due time. I fhould 
have given, you my anfwer fooner, but have been greatly 
aff! idled with the gout. 1 am very willing to inform 
you (and take your inquiry as a favour) of my inability 
concerning colours, as far as I am able from my own 
common obfervation. 
It is a family failing: my father has exadlly the fame 
impediment: my mother and one of my lifters were 
perfect in all colours : my other lifter and myfelf alike 
imperfebt: my laft mentioned filler has two fons both 
imperfebl; but lire has a daughter who is very perfect: 
/ 
I have a fon and daughter, who both know all colours 
without exception; and fo did their mother: my mo- 
ther’s own brother had the like impediment with me, 
though my mother, as mentioned above, knew all co- 
lours very well. 
Now I will inform you what colours I have the leaft 
knowledge of. I do not know any green in the world ; 
a pink colour and a pale blue are alike, I do not know 
one from the other. A full red and a full green the 
fame.
