There is a great difference between that knowl-edge which is purely intellectual and that whichis called natural knowledge. A clever man,shut up alone and allowed unlimited time, mightreason out for himself all the truths of mathe-matics by proceeding from those simple notionsof space and number of which he cannot divesthimself without ceasing to think, but he couldnever tell by any effort of reasoning what wouldbecome of a lump of sugar if immersed in water,or what impression would be produced on the?eye by mixing the colors yellow and blue. Thelate Prof. Cooke, in one of his popular lectures,says : In practical science the student is taughtto follow out a chain of probable evidence, withcare and caution to eliminate all accidental phe-nomena, and supply by experiment and o
