THE cinema has now come to be regarded as a valuable tool in the construction of a biological education. The visual images that the viewer carries away with him are necessarily more stimulating and dynamic than the static photographs of text-books. But the transitory character of a film-showing has a disadvantage in that if a mistake in visual memory is made by a pupil it may well persist, so that the aim of the authors of "Looking at Life" in supplying an elementary book which could be used as a complement to the already available biological films is admirable.
