Being Lectures on Poetry Designed (in the main) for Science Students

First published in 1951, this book is based on a course of lectures on poetry and prose given at Cambridge University during the long vacations of 1946-1950. A request for lectures of this kind came originally from a group of science students and the response was such that a course of this nature ran yearly. The purpose was to provide students from disciplines other than the humanities with the opportunity to feed their interest in English poetry and literature.
