TY - JOUR AB - IN connexion with the Refrigeration Exhibition now being held at the Science Museum, South Kensington, a guide has been prepared by Messrs. T, C. Crawhall and B. Lentaigne, which, in addition to describing the exhibits, gives accounts of the scientific principles which underlie refrigeration and of its historical development (pp. 28+2 platos. London: H.M. Stationery Office, 1934. 6d. net). A further publication which will be welcomed by all those engaged in the refrigerating industry is the “Five Year Bibliography” of the subject which has been prepared by Mr. H. T. Pledge, of the Science Library (pp. 97. London: H.M. Stationery Office, 1934. 2s. net). It is a foolscap pamphlet of 97 pages with the typed entries in two columns under the decimal classification numbers 621.56 to 58, with a short section on air conditioning under 697.9. Under “Refrigerants” 621.564 there are 8 pages of entries which include between eighty and ninety dealing with ‘dry ice’ or solid carbonic acid—621.564.23—under its various names of neige carbonique, trock-eneis, ghiaccio secco, droog Ijs, glace seche, Cold, Kold-Trol, Cardico, Drikold and others. The fact that the Science Library has prepared more than 120 bibliographies of this type on subjects varying from Bessel functions to the habits of lizards seems very little known, and much time has in consequence been wasted by research workers in collecting information on subjects in which bibliographies were already in existence.
