This volume, on the various machinery connected with the raising of ■water, is a very interesting 

 production ; not only to the Experimental Philosopher, the Mechanician, and the Operative Trides- 

 man, who are engaged in the researches and work combined with the objects specified in the 

 Treatise, but also to every ordinary reader who is solicitous to enlarge his general informa- 

 tion, and who wishes to combine amusement with the topics which attract his attention. 



It is impossible in this concise notice, to detail a minute syllabus of a book, the mere topica. 

 index of the contents of which occupies nearly eight pages, numbering about one thousand dis- 

 tinct articles ; but a general view is presented, from which the nature and value of the disser< 

 tation can easily and correctly be estimated. 



The first book, which is subdivided into eighteen chapters, comprises a narrative of the various 

 •' Primitive and Ancient Devices for Raising Water," which are exemplified by sixty-seven en- 

 graved specimens of their diversified contrivances. This is not merely a dry philosophical 

 comment, for there are many episodes commingled with it of a peculiarly interesting charac- 

 ter, of which the preliminary remarks on the historical accounts of vi-arriors, and the section 

 in chapter sixteen, on the " Flattery of Despots by Men of Science," may distinctly be mentioned. 



The second book, which includes seven chapters, describes the " Machines for Raising Water by 

 the Pressure of the Atmosphere." With this part are incorporated thirty engravings, delineating 

 the chief inventions which have been used in that department. 



The third book, containing nine chapters, develops the " Mechanics for Raising Water by 

 Compressure, independently of Atmospheric Influence," with sixty-nine pictorial representations 

 of bellows, pumps, and fire-engines. The discussions respecting water-works and fire-engines 

 are full of instruction, and combine more information upon those important topics than can be 

 found, it is believed, in any other work that ever has been published. 



The fourth book is extended to nine chapters, and displays the "Machines for Raising Wa- 

 ter, chiefly of Modern Origin, including Early Applications of Steam for that Purpose,'' with 

 thirty-one engravings. This portion of the volume is very racy, especially the details concern- 

 ing the Altars and Heron's Spiritalia, with the introductory paragraphs to chapter three, from 

 page 381 to 391, and the notice of the Eolipilic Idols. 



The fifth book, which also comprises nine chapters, with eighty-four engravings, unfolds the 

 "Novel Devices for Raising Water, with an Account of Siphons, Cocks, Valves, Clepsydrae," 

 &c., the seventh chapter of which, on Fountains, condenses a large quantum of information upon 

 that cooling and refreshing topic, which is followed by an attractive elucidation of hydraulic 

 organs. 



An Appendix, with five engravings, supplies some additional explanatory facts ; and to the 

 whole is subjoined a comprehensive index of all the principal subjects that are embodied ic 

 those pages. 



In addition to the above, the present edition contains a Supplement o^ over 

 thirty pages, on ANCIENT EOLIPILES, with some curious ilhistrations. 



The entire work, with an Illustrated Titlepage, will cost but half the price 

 of the previous editions. ^
