216 Miscellanies. 



the demonstrations which are left unsupplied, in many cases comprehend- 

 ing the entire processes which connect the enunciation of the propositions 

 with the conclusions, and the constant reference which is made, both tacit 

 and expressed, to results and principles, both analytical and mechanical, 

 which are co-extensive with the entire range of known mathematical 

 science ; but in Dr. Bowditch's very elaborate commentary every deficient 

 step is supplied, every suppressed demonstration is introduced, every re- 

 ference explained and illustrated, and a work which the labors of an or- 

 dinary life could hardly master, is rendered accessible to every reader 

 who is acquainted with the principles of the differential and integral cal- 

 culus, and in possession of even an elementary knowledge of statical and 

 dynamical principles. 



" When we consider the circumstances of Dr. Bowditch's early life, the 

 obstacles which opposed his progress, the steady perseverance with which 

 he overcame them, and the courage with which he ventured to expose the 

 mysterious treasures of that sealed book, which had hitherto been ap- 

 proached by those only whose way had been cleared for them by a sys- 

 tematic and regular mathematical education, we shall be fully justified in 

 pronouncing him to have been a most remarkable example of the pursuit of 

 knowledge under difficulties, and well worthy of the enthusiastic respect 

 and admiration of his countrymen, whose triumphs in the fields of prac- 

 tical science have fully equalled, if not surpassed, the noblest works of 

 the ancient world," — lb. 



TO OUR SUBSCRIBERS AND READERS. 



That we may in future finish a volume in the last quarter of 

 the year, and begin a new volume in the succeeding January, 

 we shall publish two numbers of this Journal in July. No. 2 of 

 Vol. XXXVI, and No. 1 of Vol. xxxvii, will appear in that month ; 

 No. 2 of Vol. xxxvii, in October, and No. 1 of Vol. xxxviii, in 

 January. This effort will be made in order to avoid the confu- 

 sion arising from linking together two years by the same volume. 



The consequent anticipation of one quarter of a year in the 

 payments, will, we trust, be readily acquiesced in by our sub- 

 scribers and agents, as this anticipation will occur but once, and 

 a full equivalent will be rendered.
