STOKES, William, was born at Brighton, Mar. 20, 1886. After achieving remarkable success in his native town, he appeared in London, and on June 18, 1861, gave his first Lecture on Memory at the Boyal Colosseum, Begent's Park, with which he was connected for about nineteen months, when it closed; and on Feb. 12, 1863, he delivered his first lecture at the Boyal Polytechnic Institution, Be- gent Street, with which he was associated for nearly nineteen years, lecturing on the last day of that institution, Jan. 21, 1882. The soundness of Mr. Stokes's Theory of Memory, the simplicity and
effectiveness of his Memory Aids, his singular gift of teaching, and his untiring energy and perse- verance, have rendered him the most eminent Professor of Memory of the age. He has lectured and taught at Christ Church, Oxford ; Trinity College, -Cambridge; and at innumerable other colleges, schools, and places of entertain- ment throughout the kingdom; and his influence has extended to the colonies, America, and abroad. In addition to his popular treatise " Stokes on Memory," he has written the standard series of Memory Aiding works on Bapid Beading, Writing, Arithmetic, Drawing, Music, and other sub- jects. He is now at the Polytechnic, which was re-opened on a fresh basis in Sept. 1882 ; and he gives frequent demonstrations of his system at the Boyal Aquarium, Westminster.
