"Our examination of the work leads us to speak most favourably of it as 

 a handbook for students. The author introduces in many parts of the work 

 paragraphs comprising physiological physics, or the application of physics 

 to the structure and functions of the human body. The laws of mechanics 

 are exemplified in the skeleton, and those of hydrostatic pressure in the 

 circulation of the blood. These additions render the volume of great value 

 to the medical student. It is our opinion that the handbook will be a useful 

 addition to the library of every medical student, as well as a serviceable 

 guide to all who are about to commence the study of physics." — From the 

 Medical Gazette. 



THE STEAM ENGINE, STEAM navi- 

 gation, ROADS AXD RAILWAYS, Explained and 

 Illustrated. A New and Cheap Edition, revised and Com- 

 pleted to the present time. By DIONYSIUS LARDNER, 

 D.C.L., &c. Formerly Professor of Natural Philosophy 

 and Astronomy in University College, London. 



One Vol. 12mo. Illustrated with "Wood Engravings. 8*. &J. cloth. 



In former editions, much space was occupied by historical and biographical 

 matter, as well as by the description of engines which have long since become 

 obsolete, and which, not forming a necessary link in the chain of invention, 

 may be considered as superfluous in a work of this description. The space 

 has been in tbe present edition more usefully occupied by other matter. 



The second and third parts are completely new. In the third chapter of 

 the second part will be found a review of the progress of Steam Navigation! 

 from its first establishment in 18P2 to the present day. This chapter also 

 contains the refutation of those absurd reports which have been generally 

 circulated, imputing to the author opinions as to the impossibility of the 

 Atlantic voyage, which are precisely the reverse of those he really expressed.
