been secured for hundreds of rare, useful and costly manufactured articles, of 

 which one could not give half the names, or they would fill the pages of this mag- 

 azine. 



It is not a scientific fact, nor an industrial fact, nor an agricultural fact, un- 

 less we may be permitted a pun, and count it as an attraction hard to beet that 

 President Arthur, the Marquis of Lome and Princess Louise, and a host of other 

 notables are coming; and I hope many readers of the Review, who will see 

 that we have reason to be properly ecstatic. 



BOOK NOTICES. 



Knight's New Mechanical Dictionary ; Edward H. Knight, A. M., LL. D. 

 In four parts, 240 pages each; 2,500 illustrations. Houghton, Mifflin &Co. , 

 Boston. $2.00 for each part. 



This is intended as a supplement to Knight's American Mechanical Diction- 

 ary, published five years ago, which was pronounced by all the students of 

 technology or mechanics the most perfect work of the kind ever issued, and 

 covers the period from 1877 to 1882. During this period the progress made in 

 the development of the mechanic arts is unprecedented in the history of the 

 world. Not only in such striking and wonderful achievements as relate to the 

 telephone, phonograph and electric light, toward which popular attention is ratu- 

 rally drawn, but in every department of apphed mechanics, there has been de-

 most sanguine expectation, and with such rapidity that even the most recent 

 records are found to be very deficient in supplying the special information most 

 desired. 



The two great exhibitions, at Philadelphia and Paris, with each of which the 

 aifthor was officially connected as delegate or commissioner, and as a member of 

 the respective juries, have brought forward a world of new matter ; and the 

 records of our own patent office, as well as the testimony of our technical jour- 

 nals, bear witness to the fact that at no period has invention been more fertile, 

 more brilliant, or more important. 



This fact and the success that the former volumes met with in all parts of the 

 world, has induced the publishers to issue another volume, thus continuing the 

 record from the date at which the former work went to press, but carefully avoid- 

 ing repetition, and aiming to furnish not only a satisfactory supplement to the 

 original work, but a book which shall have an individual and separate value as a 

 complete record of half a decade iu the history of invention. From this fact it 

 is evident that this volume forms an indispensable supplement to all works of
