A Practical Manual of Chemical Engineering

Abstract

A BOOK on chemical engineering published in England is welcome, even if only to show the growing interest in this subject. Mr. Tongue's work does more: it fills, as he claims, a gap in the literature, by dealing with the materials which modern science has placed at our disposal, and methods of using them. It is admittedly a compilation and, as such, it is bound to exhibit a certain lack of balance; for example, under the heading “Wood”, with the exception of a table of the mechanical properties of a few American woods, redwood is the only material discussed. Under “Rubber”, six pages have been transcribed verbatim from a well-known pamphlet, apparently without acknowledgment—no doubt a slip on the part of the author—and there are other abstracts which, although good in themselves, are often somewhat disconnected.
