SCIENCE. 



[Vol. XIX. No. 468 



tary Academy, and " Elementary Course in Theory of Equations," 

 by C. H. Chapman, Jolins Hopkins University. 



— A. Lovell & Co., New York, have begun the publication of a 

 series of American History Leaflets, to be issued bi monthly. The 

 first contains Columbus' letter to Luis de Sant Angel, announcing 

 his discovery. 



— Houghton, Mififlin, & Co. have just published the third vol- 

 ume of Sargent's important work on the Silva of North America. 

 It will include Anacardiaceae-Leguminosse, and, like the previous 

 volumes, will contain fifty plates drawn and engraved with the 

 utmost skill. 



— Charles H. Sergei & Co. announce a series of histories of the 

 Spanish-American Republics. The first volume, which will be 

 issued in February, will be "Peru," by Clements R. Markham. 

 It will be followed in a short time by "Brazil," by William E. 

 Curtis. "Argentine," by the Author of "An Earnest Trifler," 

 and other volumes will be issued at intervals of two or three 

 months. 



— Longmans, Green, & Co. have published a small atlas pre- 

 pared by Professor A. B. Hart of Harvard University and entitled 

 "Epoch Maps Illustrating American History." It is primarily 

 designed as a companion to the series on ' ' Epochs of American 

 History " published by the same house, of which Professor Hart 



is the editor. The author says that it is " an attempt to make 

 maps from the records — from the texts of grants, charters, and 

 governors' in.structions, and from statutes, British, colonial, state, 

 and national." It opens with a map showing the physical tea,- 

 tures of the United States, followed by several illustrating the 

 early discoveries and settlements, and others showing the growth 

 of the national territory, the settlement of disputed boundaries, 

 the growth and abolition of slavery, the civil war, and various 

 other phases of our national history. There are, however, no 

 maps of particular regions of special historical importance, such 

 as New Jersey in the Revolution and Virginia in the civil war — 

 an omission that is to be regretted. But the maps that are given 

 are excellent, and as history without maps is almost unintelligible, 

 they will be useful to historical students. 



J. B. Lippincott Company have just published a second edition 

 of Goubaux and Barrier's "The Exterior of the Horse," translated by 

 Dr. Simon J. J. Harger of the University of Pennsylvania. This 

 edition has been in preparation for three years, involving many 

 alterations, which in most cases amounted to almost a transfor- 

 mation of the old text into entirely new matter. A new plate 

 upon the age, by G. Nicolet, and fifty-three original figures have 

 been added, making the total 346 figm-es and 34 plates. 



— Benjamin Sharp, Ph.D., will teU in the February Scribner 

 some results of his Greenland explorations last summer. He de- 

 scribes what Sir John Ross, who discovered them in 1813, called

" The picture of our desolate North-western terri- 

 torjr twenty-five years ago, in contrast with its 

 civilized aspect to-day, and the pleasant features of
