THE POWER OF MOVEMENT IN PLANTS. By CHARLES DARWIN, 

 LL. D., F. R. S., assisted by FRANCIS DARWIN. With Illustrations. 12mo, 

 cloth, $2.00. 



" Mr. Darwin's latest study of plant-life shows no abatement of his power of 

 work or his habits of fresh and original observation. We have learned to expect 

 from him at intervals, never much prolonged, the results of special research in 

 Borne by-path or other subordinated to the main course of the biological system 

 associated with his name; and it has been an unfailing source of interest to see 

 the central ideas of the evolution and the continuity of life developed in detail 

 through a series of special treatises, each wellnigh exhaustive of the materials 

 available for its subject." Saturday Review. 



A PHYSICAL TREATISE ON ELECTRICITY AND MAGNETISM. 



By J. E. H. GORDON, B. A., Assistant Secretary of the British Association. 

 With about 200 full-page and other Illustrations. 2 vols., 8vo, cloth, $7.00. 



" We welcome most heartily Mr. Gordon's valuable contribution to the experimen- 

 tal side of the science. It at once takes its place among the books with which u vn-v 

 investigator and every teacher who goes beyond the merest rudiments must n 

 f<l\iip himself. There is certainly no book in English we think there is none in am 

 other language which covers quite the same ground. It records the most recent ad- 

 vances in the experimental treatment of electrical problems, it describes with minute 

 carefulness the instruments and methods in use in physical laboratories, and is prodi- 

 gal of beautifully executed diagrams and drawings made to scale." London Times.
