PHYSICAL EXPRESSION: Its Modes and Principles. By 



Francis Warner, M. D., Assistant Physician, and Lecturer on Bot- 

 any, to the London Hospital, etc. With 61 Illustrations. 12mo. 

 Cloth, $1.75. 



" Tn the term ' Physleal ExpresBioD,' Dr. Warner Jncliidfirt all those changes of form 

 and feature occurnng in the body which may be interpreted as evidences of mental 

 action. At first thought it would Bcem that facial expression is ihe most important 

 ot these outward signs of inner processes; but a little observation will convince one 

 that the posture assumed by the oody— the poise of the head and. the position of the 

 hands— as well as the many alternations of color and of general nutrltfori, are just as 

 RtrikiDg evidences of th^ course of thought. The subject thus developed by the ati- 

 thor becomes quite extensive, and is exceedingly interesting. The work is fully up 

 to the standard maintained in 'The International Scientific Series.^ '*^— Science. 



** Among those, besides physicians, dentists, and oculists, to whom T)r. Warner's 

 book will be of benefit are actors and artists. The art of gesticulation and of postures 

 Is dealt with clearly from the pcientific student's point of view. In the chapters con- 

 cerning expression in the bead, expression in the face, expression in the eyes, and in 

 that on art criticiBm, the reader miiy find many new euggestions."— PAi^ac^^/pAia

COMMON SENSE OF THE EXACT SCIENCES. By th? 



late William Kingdon Clifford. With 100 ilgures. 12mo. 

 Cloth, $1.50. 



" This Is one of the volumes of ' The International Scientific Series,' and wan origi- 

 nally planned by Mr. Clifford; but upon his death in 1879 the revision and completion 

 of the work were intrusted to Mr. G. B. Kowe. He also died before accomplishing his 

 purpose, and the book had to be finished by a third person. It Is divided into five 

 chapters, treatinj; number, space, quantity, position, and motion, respectively. Each 

 of these chapters is subdivided into sections, explaining in detail the principles under- 

 lying eoch. The whole volume is written in a masterful, scholarly manner, and Uie 

 theories are illustrated by one hundred careftilly prepared figures. To teachers espe- 

 cially is this volume valuable; and it is worthy of the most careful study."— iV^Uf York

JEIiLY-FISH, STAR-FISH, AND SEA-URCHINS. Being 

 a Research on Primitive Nervous Systems. By G. J. Romanes, 

 F. R. S., author of "Mental Evolution in Animals," etc. 12mo. 

 Cloth, $1.75. 



" A profound research into the laws of primitive nervous systems conducted by one 

 of the ablest English investigators. Mr. Komanes set up a tent on the beacb and ex- 

 amined his beautiful pets lor six summers in succession, t^uch patient and loving 

 work has borne its fmita in a monograph which leaves nothing to be said about jelly- 

 fish, star-fish, and sea-urchins. Every one who has studied the lowest forms of hfe on 

 the sea-shore admires these objects. But few have any idea of the exquisite delicacy 

 of their structure and their nice adaptation to their place in nature. Mr. Komanes 

 brings out the subtile beauties of the rudimentary organisms, and shows the resem- 

 blances they bear to the higher types of creation. His explanations are made more 

 clear by a large number of illustrations. While the book is well adapted for popular 

 read log, it is of special value to working pby Biologists." — New York Journal qj
