“We do not think that Professor Hoffding possesses the necessary qualifications to write a philosophy of religion. He is a psychologist. He is distinguished in philosophy. But it needs more than this and other gifts than this to write on Christianity. And neither the sympathy nor the theological learning requisite is found in Dr. Hoffding’s book.”

Hofmann, Ottokar. Hydrometallurgy of silver, with special reference to chloridizing roasting of silver ores and the extraction of silver by hyposulphite and cyanide solutions. $4. Hill pub. co.
7–15483.
“The book is divided into two parts, of which the first deals with chloridizing roasting of silver ores (154 pages), the second with the extraction of the silver (174 pages). The author points out in the preface that in the hydrometallurgical process for the extraction of silver from complex sulphide ores, the final result depends entirely on the quality of the roasting.”—Engin. N.
“On the whole, the book is well written, in an easy and interesting style, and even if the hypo-sulphite method has seen its day, this volume will be read with interest.” Bradley Stoughton.
