THE literature available for the guidance of scientific workers in the preparation of reports of scientific and technical papers is already considerable, as a glance at the bibliographies contained in Soule's “Library Guide for the Chemist” or the “Manual on Research and Reports” issued some years ago by the Committee of Research of the Amos Tuck School of Administration and Finance shows. The bulk of this literature is of American origin, to which indeed the two present volumes are no exception, and it cannot be said that, whether in industry generally or in particular fields of science, the scientific worker has yet shown himself anything like as competent in his standard of presentation of the results of his work as is to be desired.
