^his author's works, bat has confined himself in tlie main to 

 thoughts on moral topics, sucli as study, society and solitude, 

 friendship, and others of the like nature; and in this we think he 

 has done wisely, for such ethical sayings are the most likely to do 

 good. We cannot say, however, that we find much depth or 

 originality in Thoreau's thinking, and we doubt if he has had 

 much real influence even over his admirers. 



— A neat and useful pocket manual for army ofHcers is " Notes 

 on Military Hygiene," by Lieut. Col. Alfred A. Woodhull, which 

 has recently been published by John Wiley & Sons. The little 

 volume contains what may be called the essence of a series of 

 lectures on military hygiene, delivered by the author at the Infan- 

 try and Cavalry School at Fort Leavenworth. Though originally 

 prepared for the convenience of students, the work will no doubt 

 prove acceptable to officers of the line generally. Among the 

 topics discussed are the selection of soldiers, military clothing, 

 food, habitations, camps and marches, sewers and waste, water, 

 and preventable diseases. 



— Me,*srs. Houghton, MiflBin, & Co. have just issued another 

 •volume (Vol. 34) of their Modern Classics, — a series which Dr. 

 William T. Harris, United States commissioner of education, has 

 called an " unrivalled list of excellent works." This new volume, 

 entitled " Thackeray's Lighter Hours,'' contains "Dr. Birch and 

 his Young Friends," '• Selections from the Book of Snobs and the 

 Roundabout Papers," and " The Curate's Walk." Modern Clas- 

 sics has a very extensive sale as a school library, for which it is 

 well suited, as it contains many of the best complete stories, essays 

 sketches, and poems in modern literature, including selections 

 from the celebrated authors of England and America, and transla- 

 tions of masterpieces by continental writers. 



— William M. Goldthwaite, New York, has published a " Driv- 

 ing Road Chart of the Country surrounding New York City." This 

 chart covers every place within twenty miles radius of the City 



Hall, and in parts extends out to nearly forty. This map will be 

 specially useful to all living in or near the city, or contemplating 

 removing to it. 



— Herbert Ward, in the preface to his " Five Years with the 

 Congo Cannibals," tells his story of the rear-guard of the Stanley 

 expedition for the relief of Emin Pacha. The trials of those left 

 behind by Mr. Stanley when he pushed forward, the fate of Major 

 Barttelot and Mr. Jameson, and Mr. Ward's own part in the 

 transactions of that trying period, form an interesting ch^ipter in 

 the history of Mr. Stanley's great enterprise. 



— A map of the valley of Virginia, showing the location of all 

 the industrial towns, battle-fields, mountain-passes, and Luray 

 caverns (10 cents), is published by Alex Y. Lee, C.E., Luray, Va.

It is only within very recent years Ihat this 

 department of research has been cultivated; and 

 it is natural that the results of different workers. 

 Involving variations in method and design, 

 should show points of difference. In spite of 

 these It seems possible to present a systematic 

 sketch of what has been done, with due reference 

 to the ultimate goal as well as to the many gaps 

 still to be filled.

"We strongly recommend Dr. Brinton's 

 and Peoples*' to both beginners and scholars. We 

 are not aware of any other recent work on the 

 science of which it treats in the English language." 

 — Asiatic Quarterly. 



"His book is an excellent one, and we can heartily 

 recommend it as an introductory manual of ethnol- 

 ogy."— r/ie Monist. 



"A useful and really interesting work, which de- 

 serves to be widely read and studied both in Europe 

 and America."— -Sri<;/ifo7i CEng.) Herald. 



"This volume is most stimulating. It is written 

 with great clearness, so that anybody can under- 

 stand, and while in some ways, perforce, superficial, 

 grasps very well the complete field of humanity." — 

 Hie JSeiv York Times. 



"Dr. Brinton invests his scientific illustrations and 

 measurements with an indescribable charm of nar- 

 ration, so that 'Races and Peoples.' avowedly a rec- 

 ord of discovered facts, is in reality a strong stim- 

 ulant to the imagination."— Philadelphia Public
