In this work full details are given of the second "[olzXion of the earth, and 

 the important facts that are revealed by a knowledge thereof. This movement, 

 the Author tells us, fully explains the cause of the precession of the equinoctial 

 points, of the change in the polar distance and right ascension of the stars, of 

 the decrease in the obliquity of ecliptic, and also gives the date and duration 

 of the last Glacial Period. 



A System of Practical and Scientific Physiognomy. By 

 Mary Olmsted Stanton. 2 vols., royal 8vo, pp. xxxvi. — 1222. (Philadelphia 

 and London : F. A. Davis. 1890.) Price £2. 2s. 



This is a large and exhaustive work on a subject which has a great 

 attraction for a certain class of minds. If it be true that every face exhibits 

 either a history or a prophecy, this book may help the observer to discipher it 

 to a certain extent ; but those who believe that the proper study of mankind is 

 man, and who desire to obey the ancient advice, " Know thyself," will desire 

 some more trustworthy guide than Physiognomy. The Authoress gives the 

 results of considerable research, and of much discriminating observation, and 

 has produced a work well worthy of perusal. There are 380 illustrations, 

 mostly portraits of European and American celebrities.

 York : The American Book Company. 1890.)

 less advanced. Much care is shown in the logical arrangement of the 

 definitions, all of which are expressed in simple, concise language. Due 

 prominence has been given to the working of factors and quadratic equations, 

 while the series of exercises are well graduated, and will enable the student to 

 put into practice the knowledge gained from the study of the examples. The 

 chapters on proportion, geometrical progression, annuities, and logarithms, are 

 particularly clear and well considered.
