movements of the moon and the planets, hia catalogue of a 

 thousand stars, and his observations of comets, which were the 

 means of refuting Aristotle's opinion that these bodies belonged 

 to our atmosphere. Considerable space is devoted to Tycho's 

 work in astrology, to which he gave much attention, and in 

 which his faith, though not as entliusiastic as that of some men, 

 was never abandoned. Altogetlier, Professor Dreyer's worlr is 

 worthy of its theme, and wiU hold an^ honorable place among 

 biographies of scientific men. 



Introduction to the Study of Federal Oovernment. By Albert 

 BusHNELL Haet. (Harvard Historical Monographs, No. 2). 

 Boston, Ginn. 8°. $1 net. 



We noticed the first of these monographs a short time since, 

 and we are now glad to receive the second. It is only an intro- 

 ductory work, forming a pamphlet of two hundred pages, and the 

 author tells us in his preface that it is to be followed in due time 

 by an extended treatise on the same subject ; yet it is of real value 

 in itself. Professor Hart opens his work with a discussion of the 

 natux-e of federation and of the various types of federal govern- 

 ment that are known in history, — a discussion that shows a clear 

 view of the questions involved, and considerable power of phil- 

 osophic thought. He next proceeiJs to a brief but very clear ac- 

 count of the ancient and mediaeval confederations fi'om the first 

 conception of the federal idea among the Gi-eeks to the Holy 

 Roman Empire, then gives a description of the four great existing 

 federations, — those of the United States, Switzerland, Germany, 

 and Canada, — and closes with a short chapter on the Latin- 

 American federations, in which he has no great confidence The 

 monogiaph is written in a good style, and shows throughout not 

 only a careful study of the facts, but also the fruits of thought 

 and meditation, which are not always found in American historical 

 writings. Besides the text of the work, there is a long and 

 elaborate appendix, containing a conspectus of the four chief ex- 



isting federations mentioned above, arranged in parallel form, and 

 giving the provisions of each of the four constitutions on every 

 important point. This appendix thus (ireserits a large amount of 

 information in a form convenient for reference ; and there is also 

 another appendix containing a bibliogra phy of federal government. 

 Altogether, the pamphlet is a crelilaUe one; and historical 

 writers in our other universities will have to do better than they 

 have done heretofore if their work is to rank on a level with these 

 Harvard monographs. 



AMONG THE PUBLISHERS. 



The latest number of the " Proceedings of the United States 

 Naval Institute " opens with an interesting article on the protec- 

 tion of the hulls of vessels by lacquer, detaihnj; the results of ex- 

 periments on several Japanese men-of-war. The experiments 

 seem to prove that lacquer is a perfect protection against the action 

 of sea-water so long as the coat remains unbroken.
