author of this paper was commissioned by the Commissioner of Education to draw up a set of inquiries respecting the teaching of physics, send them to teachers, and collate and discuss the answers which should be received. The questions related to various points respecting the expediency of the teaching, the prominence and extent that should be given to it, and the method in which it should be done. Answers were received from seventy-two teachers in normal and secondary schools and colleges and universities, and other persons experienced in educational work, and are here given and reviewed.
