"It is almost useless to warn against this multiplicity of subjects which now distract boys and perplex teachers. The experiment of teaching a little of all things must be tried: it is demanded by opinion, founded on small or no reflection, it is required by competition for prizes, distinctions, and places; and it is encouraged by examinations and the questions proposed, which direct in a manner the course of education."
