Take, by way of example, the following:--Huber, the naturalist (Geneva, 1784-85); he became blind at the age of seventeen; he wrote on the labours and instincts of bees and ants, and also on education. Francis Potter (London, died 1678); he wrote on mechanics, theology, and painting. F. Carulhi (Nantes, died 1789); born blind; he wrote on music. Rev. J. Troughton (Coventry, died 1681); blind at four years of age; he wrote on theological subjects. John Stanley (London, died 1781); blind at two years old; a musical performer and composer; he wrote the oratorios, Jephthah, Zimri, etc. John Gough (Kendal, 1757); blind at the age of three years; a writer of several communications to the Manchester Society, and to Nicholson's "Journal on Botany and Natural Philosophy." Sir John Fielding (Westminster, died 1780); blind from youth; police magistrate, and author of the "Universal Mentor." John McBeath (Dalkeith, died 1834); blind at an early age; he studied music and mathematics, and wrote on "Inventions for the Blind." He was a blind teacher in the Edinburgh school. James Wilson, author of the "Biography of the Blind." James Holman, whose published travels through many portions of the world have excited very general curiosity and interest. Alexander Rodenback, member of the Belgian Chamber of Deputies, and one of the principal actors in the Belgian revolution; he was a supporter of the democratic party, and often made the chamber ring with his original and eloquent speeches. We might add greatly to this list, but we select the above merely as examples, to show how, when the acquisition of knowledge is debarred at the entrance of the eye, the mind will collect it through the inlet of other senses. Of the numerous schools of instruction for the blind, of which our country may well be proud--of the systems of training pursued in them--of the labours of pious individuals, some themselves blind--it is not our place here to speak. We devoutly pray that the blessing of the all-seeing God may be with them and upon them!
