the back room, having no opening, 
but into a fmall clofe yard, fur- 
rounded with high walls, was very 
dark; he wrote in the back room, 
and ufed to conie from that into the 
front room to breakfaft, &c. His 
fight grew weak, and he had a con- 
ftant pain in the balls of his eyes; 
he tried vifual glafles, and {poke

ing foon convinced, that the coming 
fuddenly out of his dufky ftudy, into 
the full blaze of fun-fhine, and that
