Abstract
A RECENT publication offers a priced catalogue of representative items in the range of equipment for visual aids in education (Visual Aids : Notes on some Modern Apparatus. By Wilfred J. Garnett. Pp. 36. Manchester : Flatters and Garnett, Ltd., 1947). Each instrument is concisely described, and the pros and cons of each corresponding method of visual presentation are outlined with admirable fairness and objectivity. The most spectacular of the items listed are probably the microprojector and the patent demonstration mirror ; the former as an example of functional efficiency, the latter in view of its comparatively recent development as a visual aid. As a guide to the purchaser of equipment who seeks the best possible results in the way of visual reproduction the author is thoroughly dependable. (The section on "Types of Screen" is particularly helpful, and the actual specimen of ‘‘beaded screen material does all that is claimed for it.) Technical perfection, however, is not always the last criterion. The technical limitations of film strip sometimes make slides preferable. Yet the growing popularity of film strip among teachers cannot be questioned. The advantages of lightness, compactness and, above all, cheapness are overwhelming. Film strip has come to stay ; can science now produce the non-scratch film?
