“The first chapter deals briefly and concisely with the instruments and materials required in topographic drafting. The next two chapters take up the subject of paper and of plotting. The remaining chapters take up the subjects of drafting and the symbols used in drafting topographic maps, in ink and in colors, and the methods of representing surface form. This is followed by a brief treatise on earthwork and earthwork computation.”—Engin. N.
“Here is a book that makes a field of its own, and for which there is a place on shelves of all engineers and surveyors who have to do with topographic drafting. The book is concisely and clearly written. In reviewing so well written a text-book it seems ungracious to be critical over trifles.”

Danneel, Heinrich. Electrochemistry; v. 1, Theoretical electrochemistry and its physico-chemical foundations; tr. from the Sammlung Göschen by Edmund S. Merriam. *$1.25. Wiley.
7–7516.
v 1. Treats of the modern theories of electrochemistry, as well as their physicochemical foundations. Explains the terms work, current, and voltage, and discusses gas laws, osmotic pressure, theory of electrolytic dissociation and conductivity, ionic theory, electromotive force, the galvanic current, polarization, electrolysis and the electron theory.
“The average student who is called upon to study the ionic theory will obtain, we venture to think, a better grip of the subject by a study of Danneel’s book than from that of Abegg. The latter book treats the subject more fully but Danneel’s style is more interesting, and he leaves none of the salient facts out.”
