The perceptive efSciency of the other senses besides touch, the author considers to 
be. in a mat measure, dependent on the adjustnieiils ctfecled through the medium 
•flie muactilar sense; for if we would have distinct perceptions, we must look and 
lislm with adjusted eyes and ears. , 
But besides this, the anllior observes, that tho mere ndjustmciit of the eyes and ears, 
ibbsuli theae orwans have lost their special gciisntions, wd* the persons labouring 
witrw<i\ deprivations to interpret tlic communications addressed to them by the 
ttub: and this he thiiih* is the explatmtion of the fact observed bv all msfnictors ot

tmembered to have been perceiveil. oi can *lill_mukc iinprc-HHinns, however lamt and
