ISLINI) 721 to render this apparent the due cultivation of the sense of feeling is all that is required. Touch differs from sight in many respects, but chiefly in this, that while sight can take in at one glance many objects included within a vast area, touch can only convey to the brain by one act of con- tact the impression of the first small point that arrests its progress. Let a small horizontal line be made on a piece of paper, the person who wishes to feel it proceeds from the left side of the paper quite unconscious of what may meet his finger ; he presently comes in contact with a point, which fact with more than light- ning speed is conveyed to the brain. Now it is obvious that if it were possible to convey to the brain a distinct idea of one special letter or word every tune the finger comes in contact with a point, ' tangible ' reading would reach perfection. The first thing is to select the most tangible characters, viz., those whose properties can be perceived immediately that the finger comes in contact with them." On the other hand, the Rev. Mr. Johns, chap- lain to the asylum for the blind, St. George's Fields, London, says : " Sooner or later some one system of embossed printing will be gen- erally adopted, and it must embrace the fol- lowing features : It must resemble as nearly as possible the type in use among seeing men ; that the blind scholar in learning to read may have every possible help from his remembrance of letters he may once have seen, but which now his fingers must feel for him, or from any one who can read an ordinary book ; or, if need ^be, that a friend may read to him." Systems of notation in raised characters have been invented by Rousseau, Braille, Guadet, and Mahoney, and possess merit, inasmuch as they permit the pupil to record any piece of music for future reference ; but the principal method of cultivating music by the blind must always be by the ear, and in this they excel. As to the extent of the misfortune of loss of sight as compared to that of loss of hearing and speech, Mr. Johns substantially says: "At first one would be naturally led to suppose that the condition of the blind man is by far the most deplorable ; that his isolation is more EMINENT BLIND PERSONS.
