PHYSICAL EXPRESSION! Its Modes and Principles. By 



FRANCIS WARNER, M. D., Assistant Physician, and Lecturer on Bot 

 any, to the London Hospital, etc. With 51 Illustrations. 12mo. 

 Cloth, $1.75. 



&quot;In the terra Physical Expression, 1 Dr. Warner included all those changes of form 

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

 action. At first thought it would seem that facial expression is the most important 

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

 that the posture assumed by the body the poise of the head and the position of the 

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

 striking evidences of the course of thought. The subject thus developed by the au 

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

 to the standard maintained in The International Scientific Series. 1 &quot;Science. 



u Among those, besides physicians, dentists, and oculists, to whom Dr. Warner s 

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

 is dealt with clearly from the scientific student s point of view. In the chapters con 

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

 that on art criticism, the reader may find many new suggestions.&quot; Philadelphia 



COMMON SENSE OF THE EXACT SCIENCES. By the 



late WILLIAM KINGDON CLIFFORD. With 100 Figures. 12ino. 

 Cloth, $1.50. 



&quot;This is one of the volumes of The International Scientific Series, 1 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. C. R. Rowe. He also died before accomplishing hia 

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

 chapters, treating number, space, quantity, position, and motion, respectively. Each 

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

 lying each. Tlie whole volume is written in a masterful, scholarly manner, and the 

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

 cially is this volume valuable; and it is worthy of the most careful study.&quot; New York

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

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

 F. R. S., author of &quot;Mental Evolution in Animals,&quot; etc. 12mo. 

 Cloth, $1.75. 



&quot; A profound research into the laws of primitive nervous systems conducted by one 

 of the ablest English investigators. Mr. Romanes set up a tent on the beach and ex 

 amined his beautiful pets for six summers in succession. Such patient and loving 

 work has borne its fruits 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 life on 

 the sea-shore admires th.-se objects. &quot; But few have any idea of the exquisite delicacy 

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

 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 

 reading, it is of special value to working physiologists.&quot; New York Journal Q/
