D.Wood of Philadelphia, although one of the finest organists in the country, has been totally blind for years.

It is said that he acquires new compositions with almost as great facility as one not afflicted with his infirmity.

"Blind Tom," a semi-idiot and blind negro achieved world-wide notoriety by his skill upon the piano.
In some extraordinary cases in which both sight and hearing, and sometimes even taste and smell, are wanting, the individuals in a most wonderful way have developed the sense of touch to such a degree that it almost replaces the absent senses.

The extent of this compensation is most beautifully illustrated in the cases of Laura Bridgman and Helen Keller.

No better examples could be found of the compensatory ability of differentiated organs to replace absent or disabled ones.
Laura Dewey Bridgman was born December 21, 1829, at Hanover, N.H.
