 OGY. By Professor T. H. Huxley, F.R.S. With 

 82 Illustrations. Forming Volume 28 of "The In- 

 ternational Scientific Series." i2mo, cloth, Si-75- 



Tbe object of Professor Huxley's new book is to afford an opportunity 

 to students to commence the study of zoology by means or a carelul veri- 

 fication of nearly all that is known concerning a single animal, the common 

 crayfish. The book is termed an " Introduction to Zoology ■ ' for whoever 

 will follow its pages, crayfish in hand, and will try to verify for himself the 

 statements which it contains, will find himself brought face to face with all 

 the great zoological questions which excite so lively an interest at the pres- 

 ent day." 



CEREMONIAL INSTITUTIONS. 



Being Part IV. of "The Principles of Sociology." (The 

 first portion of Volume II.) By Herbert Spencer. 

 i2mo, cloth. Price, $1.25. 

 ■In this instalment of 'The Principles of Sociology,' Mr. Herbert 

 Spencer gives us a monograph complete in itself, of moderate length, and 

 on a subject which affords considerable literary opportunities. The oppor- 

 tunities have been well used, and it needs no historical cnthusiam for 

 primitive humanity to find the book as entertaining as it is instructive. 

 The leading idea which Mr. Spencer develops and illustrates all 

 through the book is that, in the early history of society and institutions, 

 form has gone before substance."— Saturday
