The Supplementary Volume, which has now become very -scarce, has never been incorporated with the following 

 editions of the ' Treatise,' and contains all Prof. Boole wrote with a view to enlarge the original work in a later edition. 



'A standard text-book on /H/Tw/ifiW Equations, including original matter on integrating factors, singular solutions, 

 and especially on symbolical actions.' Prof. Cajori.

A so-called ' third edition ' is a verbatim reprint of that of 1872, 



'Of very high merit, and including much original research.' D. N. B. 



1 To a certain extent these [the above two] works embody the more important discoveries of their author. In the 16th 

 and 17th chapters of the Differential Equations we find, for instance, a lucid account of the general symbolic method, tho 

 bold and skilful employment of which led to Boole's chief discoveries, and of a general method in analysis, originally 

 described in his famous memoir printed in the Philosophical Transactions for 1S44. Boole was one of the most eminent of 

 those who perceived that the symbols of operation could be separated from those of quantity and treated as distinct 

 objects of calculation.' W. S. Jevons, F. /,'.>'.

'James Booth and James MacCullagh (q. v. po?t) were; two of the earliest British writers in the XIX. Century to take 

 up the subject of analytical geometry.' IF. W. R. Ball. The chief results of the former's labours are contained in the

 Interesting as one of the very few trigonometrical tables dividing the quadrant into 100 parts, the outcome of the 



decimalisation mania then raging in France. 



Borda was not only one of the greatest mathematicians of his time, but the reformer of French naval architecture 



many years before the Revolution. His name is still borne by one of the chief training-ships of the French Navy.

The translation of the foregoing work, with an appendix not contained in the original. It is of special interest on 

 account of its translator, a German professor at Cassel, who fled to England to avoid punishment for theft. He was elected 

 a Fellow of the Royal Society, but struck off the rolls on his antecedents becoming known. He was the author of the 

 original ' Baron Munchauseri ', and a swindler of a most interesting type. ' In the autumn of 1791 Raspe went on a tour in 

 the extreme North of Scotland, where he professed to discover signs of vast mineral wealth. To sustain Ms reputation as 

 a mineralogist he brought out, in 1791, a translation of Baron Born's new process of amalgamation. By plausible 

 manoeuvres lie inveigled aloeal magnate. Sir John Sinclair of Ulbster, into disbursing large sums for preliminary operations. 

 When the time came for the fruition of his schemes, Raspe disappeared. The incident was crystallised in a tradition which 

 sir Walter Scott utilised in The Antiquary [where Raspe ligures in the character of Dvttzterswlwl].' D. N. H. Set-
