A treatise on probability.
First edition, an early issue without the errata slip at p. 423, of this mathematical-philosophical work, in which Keynes sought to establish a mathematical basis for probability theory as Russell and Whitehead had done for symbolic logic. Russell wrote of this work “the mathematical calculus is astonishingly powerful, considering the very restricted premises which form its foundation... the book as a whole is one which it is impossible to praise too highly” (quoted in DSB). The Treatise grew out of Keynes’ fellowship dissertation and represents a contribution of the first importance in its field, tackling the problems of induction and the analysis of statistical inference. A further admirable feature of the work is the wealth of historical information supplied; the bibliography listing 600 works updates the earlier treatments of Todhunter and Laurent.
DSB VII, p. 317; Institute of Actuaries, p. 91; Moggridge A3.1; “Utrecht” (1949), p. 1039.

ADAMS, John Couch.
The scientific Papers … edited by William Grylls Adams … with a Memoir by J.W.L. Glaisher.
First edition of the posthumously published collected papers of the Cambridge mathematician and astronomer, John Couch Adams (1819–1892). ‘In retrospect Adams’ many mathematical and astronomical achievements pale in comparison to his analysis of the orbit of Uranus and his prediction of the existence and position of Neptune at the age of twenty-four. Much of his later work has been superseded, but as the co-discoverer of Neptune he occupies a special and undiminished place in the history of science’ (DSB).
Remarks on Dr. Price’s observations on the nature of civil liberty, &c.
First edition, one of two issues published in the same year. A reply to and critical commentary on Richard Price’s discussion of American independence, reaffirming the English claim to sovereignty over America. Possibly penned by a member of Hume’s circle, the pamphlet was judged to be ‘written with less invective, and more decency, candour and moderation, than have lately appeared in the productions on that side of the American dispute’ (Sabin).
