..and the exploration of the desolated islands of that neighborhood 

 formed one of the most inteiestinR parts of the work. Deptlis 

 were reached in the Atlantic exceeding 4.500 fathoms, and a line 

 across the South Pacific was the first ever made in deep-sea sound- 

 ing. The visit to Australia was especially interesting. The 

 opinion of the author is highly favorable to that growing empire 

 of the distant seas. He thinks the '-working people" of Aus- 

 tralia have more influence than elsewhere, and that their average 

 intelligence exceeds that of our own people even. The four 

 millions are "a whole-souled and gallant race,'' and the visitors 

 "left their country with a genuine love for the people and a firm 

 .belief in their future greatness." The " Entprprise '' sailed on 

 Jan. 3, 1883, and went out of commission, after having thus in 

 three years circumnavigated the globe, March 31, 1886. The log 

 of the sounlings, aud the roll of the officers and men, are ap- 

 pended to the book, which is continuously of interest from its first 

 page to the last. 



Elements of Graphical Statics. Bv L. M. Hoskins. New York 

 and London, Macmillan & Co., 1893. 8vo. pp. viii., 191. 

 PI. V. $2.25. 



This work is an elementary text-book for use of students in 

 engineering. Fundamental principles and simple methods of 

 treatment are illustrated, and illustrated well. The funicular and 

 other polygons, and figures related to them, are deduced from 

 statical principles. The theory of elasticity is omitted. Bow's 

 notation has been adopted and extended, and the lettering of 

 •both the force and the space diagrams is' thus made at once con 

 venient and intelligible. The whole constitutes an excellent 

 graphical discussion of the general and fundamental principles of 

 mechanics, and in such form as to be especially useful in applica- 

 tions by the engineer in design and construction. The tracing of 

 the forces involved in the framing of structures and the relations 

 of efforts and resistances in such constructions is, by these 

 ■methods — now becoming well known and extensively applied — 



made both easy and simple. The work is likely to prove valuable 

 both in instruction and in ofiBce work. 



AMONG THE PUBLISHERS. 



The ninth volume in the series of technological handbooks 

 issued by George Bell & Sons, London (Macmillan, New York), 

 is devoted to ''Silk Dyeing, Printing, and Finishing," by George 

 H. Hurst, F.C S. The substance of the book consists of a series 

 of articles contributed to a technical journal, though they have 

 been revised and to some extent rewritten. In addition to these 

 there are added chapters on silk printing and finishing, and on 

 the testing of dyed silks. The methods of using all the new coal- 

 tar colors, which have of late years led to new developments in 

 silk dyeing, have been included. The book is a thoroughly prac- 

 tical one, not a mere collection of recipes — though recipes are 

 notlacking. The appendix contains a series of patterns illustra- 

 tive of the tints and shades produced in the dyeing of silks. (337 

 pages. 13°. $2.) 



— Macmillan & Co. have just issued a revised and enlarged 

 second edition of " Blowpipe Analysis," by J. Landauer, member 

 of the Imperial German Academy of Naturalists (authorized 

 English edition by James Taylor, B.Sc, Wh. Sc, A.R.S.M. The 

 soundness of the principles on which the work is based is attested 

 by the favorable reception accorded to it in the various languages 

 into which it has been translated, as well as by the fact that new 

 editions have been found necessary. In the present edition not 

 only has the text been completely revised, but new methods of 

 approved value have been incorporated, so as to bring the work 

 up to the present time. Some additional details of manipulation 

 will be found of value by readers who are working up the sub- 

 ject without a teacher. A handsome plate of the spectra of the 

 metals of the alkalies and alkali groups, from the drawings of 

 Bunsen and Kirchhoff forms the frontispiece. (173 pages. 13".

Bffspepsia 



Dr. T. H. Andrews, Jefferson 

 Medical College, Philadelphia, says of 



Horsford's Acid Phosphate. 



"A wonderful remedy which gave me 

 most gratifying results in the worst 

 ■forms of dyspepsia." 



It reaches various forms of 

 Dyspepsia that no other medi- 

 cine seems to touch, assisting 

 the weakened stomach, and 

 making the process of diges- 

 tion natural and easy.
