^nd the likp is mention but by few Authors, I imagin d 
^hat the follomng Tranfcript of two Letters he was pleas d 
te fend me about it, might not be unwelcom to you, and 
therefore I took this opportunity of conveying it to your 
hands. 
Firft Let. ' I was lately in Suffolk^, and there met with a 
'pretty odd but curious cafe relating toVifion,- which 
' I thought then had fon\ething of /v^r/^y, and continue 
* ftill in the perfwafion. A Qentleman gave me the Hiftory 
'of it, and because his Servant, who was concerned iu 
'it, was theain the houfe, I had the opportunity fully to 
* inform my felf, and if there be any Queftions you would 
'have propos'd, lihall fhortly fee him again. 
' The Gentleman propounded the Cafe himfelf, to know 
' the Phylofophy of it, and what fhouid be that particu- 
'lar i5j^z^r^ in his Servants -Ej^, that he fliould fee io a- 
' cutely and ftrenuoufly in the day^ aadbe juft like a poft 
' fo foon as the iS^;? fet. The young man may be towards 
' 20 years of age, and all the day hath as good a fight, if 
'nocbetterj than any of the family i diflinguiftiethat as 
' great a diftaace any objedt ; fees either nigh at haiid or 
' far off, or any of the intermediate fpaces as well as any 
'body, and with as much vigour and unweariednefs>^ but 
'when twilight once comes, is (z% the Proverb fays J 
'blind as a Beetle; fees nothings runs againft Gates, 
'Polls or Rails (any thing either higher, lower, or level 
' to his Eyej and canno't without great difficulty direct 
'himfelf Neither is all this from the want of any vi- 
' goroiis influence from the Rays of the Sun, as I conceive; 
' for when he is at home and in the houfe, he tun^bles b- 
'ver Stools, runs his head againft Doors and cannot 
'fee or direft himfelf colerabry well either by the greater 
'or leffer lights of the fire and candle ; but commits 
'pleafant miftakes, is apt to complement your feet as 
'readily a5 prefent you ftekdily with a glafs of Wine,
