simplified in application by the aid of a general table, and illus- 

 trated by rules and examples for various problems of location.

— Silver, Burdett, & Co. have now ready "The Teacher's 

 Handbook of Slojd as Practised and Taught at Naas," by Otto 

 Salomon, assisted by Carl Nordendahl and Alfred Johansson, and 

 translated and adapted for English teachers by Mary R. Walker 

 and WiUiam Nelson. The volume belongs to the new department 

 of wood-handicraft or educational carpentry, already finding a 

 place in our advancing school system, and is an able exposition 

 of the work done by the famous school at Naas, Sweden. It con- 

 tains explanations and detaOs of each exercise and is generously 

 illustrated. 



— "Heredity, Health, and Personal Beauty" is the title of a 

 book published recently by F. A. Davis, Philadelphia. The au- 

 thor is John V. Shoemaker, M.D., who is a professor at the Medi- 

 co-Chirurgical College of Philadelphia. There seems to be some 



■confusion in the matter brought between the covers of this book; 

 for, while the main portions are devoted to the laws of health as 

 understood by the author, there is introduced considerable matter 

 that has a bearing primarily on the doctrine of evolution, and not 

 directly, at least, on the preservation of health. The author is an 

 advocate of all things moderate in this life. The mode of treat- 



ment of the subject is such that the non-professional reader can 

 readily follow. Not only are there given suggestions as to the 

 mode of life most likely to lead to general good health, and con- 

 sequent good looks, but the methods considered best for the care 

 of the skin, nails, and hair are discussed in several long chapters. 



— The Johns Hopkins Press are preparing a volume on the 

 " Spanish Institutions in the South-west," by Frank W. Blackmar, 

 professor of history and sociology in the Kansas State University, 

 which wijl be ready shortly. The work is a study of the social 

 and political institutions of Spain as represented by the life of the 

 Spanish colonists in America, consequently it treats of the found- 

 ing of the Spanish missions in California, Arizona, New Mexico, 

 and Texas, and portrays the civilization established by the padres, 

 the social condition of the Indians, and the political and social life 

 of the pioneers of the South-west. 



— Hon. Carroll D.Wright will begin in the October Popular 

 Science Monthly a series of papers under the title " Lessons from 

 the Census." In the first of these he sketches the changes in scope 

 and methods which the United States census has undergone in the 

 past hundred years, and shows that its immense growth has made 

 it a somewhat clumsy machine. The series of articles on Ameri- 

 can industries will be continued in the same number with a fully 

 illustrated account of "The Manufacture of Steel," by William F. 

 Durfee, giving the histoiy of the industry from colonial times to
