bo other than this, Itook Spe&acles that had the largeft Cir- 
cles clofe to the femi-circles, on the over-part, on botk fides, 
I cut the bone ^ then, taking out theGlafles, I put black Sfanifh 
leather taper-wife into the emptied circles, which widetfd enough 
(together with the increafing widenefs of the Leather,) took in 
my whole eye at the wider end 5 and prefently I faw the benefit 
through the letter taper-end ,. by reading the fmalleft Prints that 
are, as if they had been a large and fair Chara&er. I cauPd a 
Glover to fow them with a double-drawn ftitch, that they might 
have an agreeable roundnefs, and exclude all rayes of light. So I 
colour'd the Leather with Ink, to take off the glittering. And 
this was all the trouble I had, befides the pra&ice and patience in 
ufing them. Only, finding that rfie fmaller the remote orifice 
was, the fairer and clearer the fmalleftr Prints appear'd$ and the 
wider that orifice was,, the larger Objeft it took in, and fo requi-

very end of my little finger into the orifice of thelefTer, but the

I can infert into the orifice of the wider. Sometimes I ufe one 
eye, fometimes another, for eafe by the change; for you muft 
expe& that the vifual rayes of both eyes will not meet for mutual 
affiftancein reading, a when they are thus far divided by Tubes 
©f that length. . 
The lighter the fluff is*, the lefr it will cumber. Remember 
alwayes to black the infide with fome black that hath no luftre

helpful to them,, that have need of them, To me it was not ne- 
ceffary, but I conceive it convenient, that Velvet or fonae gentle 
Leather ihonld be faftned to theTabulous part next the eyes, to 
jffeadow them from all the encompaffing light.
