 Calculus of Deductive Reasoning, Svo. buckram, t. e. g. (very scarce), 18s 



Cambridge, Macmillan, Barclay ^ and Macmillan, 1847 

 Very interestinj; as containing the leading principles afterwards elaborated in the Z/aw.s 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 cliaracteristic in his early publishing days of Daniel Macmillan.

'A standard text-book on DijJ'c initial Kquutlom, 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 IGth 

 and 17th chapters of the Dtfftrcntial Equotlovs we tind, for instance, a lucid account of the general symbolic method, the 

 bold and skilful employment of which led to 13oole's chief discoveries, and of a general method in analysis, originally 

 described in his famous n^emoir printed in the Philosophical 'rransactions 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.' — Profesanr Stanky Jevons.
