15761 BOOLE (George, F.R.S.) The MATHEMATICAL ANALYSIS of LOGIC : an Essay towards a 

 Calculus of Deductive Reasoning, Svo. buckram, t. e. g. (VERY SCARCE), 18s 



Cambridge, Macmillan, Barclay, and Macmillan, 1847 



Very interesting as containing the leading principles afterwards elaborated in the Laws of Thought, and of importance 

 for having created symbolic and mathematical logic. It is also a witness to the appreciation of power in a young writer 

 already characteristic in his early publishing days of Daniel Macmillan.

15763 TREATISE on the CALCULUS of FINITE DIFFERENCES, 2nd [final] Edition, edited [and 



greatly enlarged] by JOHN FLETCHER MOULTON [LORD MOULTON], post Svo. cl., uncut (SCARCE), 

 1. \s 1872 



One of the very few treatises on its subject in existence. A so-called ' third edition ' is a verbatim reprint of that of 

 1872. 



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



15764 TREATISE on DIFFERENTIAL EQUATIONS; 4th [last] Edition [edited by ISAAC 



TODHUNTER, F.R.S.], with plate, post Svo. buckram (SCARCE), 15s 1877 



'A standard text-book on Differential Equations, including original matter on integrating factors, singular solutions, 

 and especially on symbolical actions.' Prof. Cajori. 



' To a certain extent these [the above two] works embody the more important discoveries of their author. In the ]6th 

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

 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 IS 14. 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.' Professor Stanley Jevons.
