These observations furnish us with a practical illustration of the fact that 

 these vegetable structures of low degree of organization, are not necessarily con- 

 stant in form and structure, but are liable to vary greatly under different condi- 

 tions of temperature, moisture and exposure, and that they are associated with 

 fermentation of varying rapidity as well as with products which are more or less 

 dissimilar. They furnish one instance of the effect which environment has upon 

 the individual.

Anthropology. By Edward B. Tylor, D. C. L. , F. R. S., with illustrations; 

 pp. 448, i2mo., New York, D. Appleton & Co., 1881. 



This work is announced as "an Introduction to the Study of Man and Civil- 

 ization " and it is at least safe to say that no better one has been presented by any 

 author. It covers the whole subject of the science of Man and, without dry and 

 burdensome technicalities, places laefore the student all that is necessary for him 

 to know before commencing his own investigations or the study of elaborate 

 works devoted to special branches or departments of Anthropology. 



The scope of the work is fully shown by the titles of the chapters : Man, An- 

 cient and Modern; Man and other Animals; Races of Mankind; Language; 

 Language and Race; Writing ; Arts of Life ; Arts of Pleasure ; Science ; The Spirit 

 World; History and Mythology, and Society. All of these subjects are fully il- 

 lustrated with appropriate and excellent engravings, and the author has presented 

 his theme in a logical and progressive form from beginning to end of the volume. 

 No writer of the present day has had greater experience nor made more careful 

 researches in this field, nor is any more happy in expressing himself acceptably 

 to the general reader. His introductory chapters on Man, Ancient and Modern, 

 and on Man and other Animals, bring the whole subject before the student in a 

 condensed yet comprehensive form, and serve as a foundation, not only for his 

 (the author's,) subsequent chapters, but also for the student to build upon, no 

 matter how extensive his future researches may be. 



To any one intending to make Anthropology a specialty, no work that we 

 know of is so fitting as a preliminary text book and guide. 



Illusions : a psychological study. By James Sully, New York ; D. Appleton 

 & Co., 1881. For sale by M. H. Dickinson, $1.50. 



This work is the thirty-third volume of the International Scientific Series, 

 and is one of the most interesting of that valuable series. The author takes a 

 wide survey of the field of error, embracing in its view not only the illusions of 

 sense dealt with in treatises on physiological optics, etc., but also other errors
