- Charles Scribner's Sons issued on Aug. 8 Stevenson's longexpected book on Samoa, entitled “A Footnote to History,” being a narrative of the varied history of that island for the past eight years.
-J. B. Lippincott Company's August Bulletin of New Publications contains, among other announcements, the following: “Photography: Its History, Processes, Apparatus, and Materials. Comprising Working Details of all the more Important Methods,” by A. Brotbers. In the preparation of this work, the author's aim has been to produce a Handbook for the Use of Students of Photography, which should give the results of practical experience, and include – as far as possible within a moderate compass information gathered from many sources, and not readily accessible. The newer methods have been dealt with in sufficient detail, ard special attention given to the processes in use prior to the introduction of the gelatino-bromide method. Some of these processes are in danger of being neglected through the facilities which the newer methods have introduced. But, as Professor Brothers demonstrates, the new processes do not give results equal to the old, and are totally unsuitable for some purposes such as making negatives for photo-lithography, and in various other ways. W bere practicable, the plates illustrate the processes described,
thus making the work distinctly more serviceable to students. “In Starry Realms: a New Work on Astronomy," by Robert S. Ball; “Regional Anatomy in its Relation to Medicine and Surgery,” by George McClellan, M.D.; " Steam Boilers: their Defects, Management, and Construction," by R. D. Monro.

- Outing for August opens with the first instalment of Wheelman Frank G. Lenz's description of a cycling tour around the world. The rider is at present somewhere on the broad western plains, en route for the Pacific coast, and during his two-year jaunt he will traverse Japan, China, India, Persia, Turkey, Austria, Germany, Holland, France, England, Scotland, and Ireland. Mr. Lenz will communicate his experiences to Outing from convenient points of his journey, illustrating bis articles by photographs taken by himself. The opening chapter describes the trip
