A Report on Trichinosis, as observed in 

 Dearborn County, Indiana, in 1874. By 

 George Sutton, M. D. Aurora, Indi- 

 ana. Pp. 23. 



This is a remarkably clear and interest- 

 ing history of an outbreak of trichina dis- 

 ease that was clearly traced to the eating 

 of smoked but uncooked sausage. The 

 disease was fatal in several cases, but the 

 larger proportion of those attacked recov- 

 ered. The author describes the symptoms 

 of the disease, and the several modes of 

 treatment that were adopted. The occur- 

 rence led to an extended examination of 

 the pork produced in several counties in 

 Southern Indiana, when it was found that 

 from three to sixteen per cent, of the hogs 

 that came under observation contained tri- 

 chinae. Though full of important informa- 

 tion for the doctors and the public, this 

 paper is, for pork-eaters, any thing but 

 pleasant reading. 



Preventive Medicine. By C. C. F. Gat, 

 M. D. Pp. 12. 



The author of this address defends the 

 paradox that disease is the normal condi- 

 tion, while health is the abnormal condition 

 oF our race. If this is the case, then pro- 

 phylaxy and sanitation must be up-hill work 

 indeed. Still to this work Dr. Gay does not 

 hesitate to address himself, and his pam- 

 phlet contains many timely observations on 

 various insanitary conditions of modern life. 



Health Fragments; or. Steps toward a 

 True Life. By George H. Everett, 

 M. D., and Susan Everett, M. D. New 

 York: Charles P. Somerby. Pp. 306. 

 Illustrated. Price, $2. 



This book contains a few good things, 

 that have been said a hundred times before, 

 and that are here scattered through a large 

 amount of nonsense which might better have 

 been left unsaid. 



Mineral Deposits in Essex County, Massa- 

 chusetts, especially in Newbury and 

 Newburyport ; with Map. By Chas. J. 

 Brockway. Newburyport, 1875. Price, 

 50 cents. 



This is a pamphlet of sixty pages, con- 

 taining a popular account of the discovery, 

 opening, and mode of working, of the new 

 silver and lead mines in the locality named. 



Aerial Locomotion ; Pettigrew vs. Ma- 

 rey. By Prof. Coughtrie. London, 

 1875. Pp. 20. 



On the first page of this pamphlet the 

 author says his object is to show that, not- 

 withstanding certain apparent differences, 

 Pettigrew and Marey essentially agree in 

 their views on the subject of flight. But 

 the real object, as it appears from the re- 

 maining pages, is to prove by citations from 

 both authors that Pettigrew anticipated 

 Marey in most of his results, the latter, in- 

 deed, having claimed as original a great deal 

 for which he was clearly indebted to Dr. 

 Pettigrew. It is the old fight over again 

 concerning priority of discovery, and in this 

 case, according to our present lights, Petti- 

 grew appears to have the best of the battle. 



Half-Hour Recreations in Popular Sci- 

 ence. Boston : Estes & Lauriat. Price 

 per number, 25 cents. 



Number 13 of this series contains Tyn- 

 dall's paper on " The Transmission of Sound 

 by the Atmosphere," and an account of 

 "Gigantic Cuttle-Fishes," by W. Saville 

 Kent. In this paper the author recites the 

 records of early observations of these mon- 

 stars, the stories about which were consid- 

 ered doubtful until the recent discoveries 

 off the coast of Newfoundland. The bulk 

 of the article is a history of these later dis- 

 coveries. 



Number 14 is on " The Glacial Epoch 

 of our Globe," by Alexander Brown. This 

 is an interesting popular statement of how 

 the theory of a glacial epoch arose, and of 

 the investigations and theories relating to 

 the constitution and movements of glaciers 

 of celebrated observers. The number is 

 illustrated. 



Number 15 gives Balfour Stewart's ad- 

 dress on " The Sun and the Earth ; " a pa- 

 per on "Force electrically exhibited," by 

 J. W. Phelps ; and two short articles enti- 

 tled respectively " Weighing the Earth in 

 a Coal-Pit," and The "Influence of Violet 

 Light on the Growth of Animals and Plants."
