 Tables, exhibiting at one View, the Values of Lives, for different Rates of Interest; 4th Edition, with 

 Tables for 3 and 3^ % : Simpson (Thomas; f.r.s. ) The Doctrines of Annuities and Reversions,

 Annuities by Approximation, without Tables, with diagrams — 2 vols. 8vo. in 1, old calf, rebacked, 

 8s M 1752-42 



The first work contains the author's ' celebrated hypothesis, that the decrements of life are in arithmetical progression. 

 The appearance of Simpson's Doctrine of Annuities in 1742 gave occasion to a groundless imputation of plagiarism made by 

 De Moivre in the second edition of his work.*— i). N. B.

' He introduced the principle that the probability of a compound event is the product of the probabilities of the single 

 events composing it, and the whole subject, Todhunter remarks, ' owes more to him than to any other mathematician, 

 with the single exception of Laplace'.' — Miss Agnes M. Gierke. 



' His work on the theory of probability surpasses anything done by any other mathematician except Laplace. His 

 principal contributions are his investigations respecting the Duration of Play, his Theory of Recurring Series, and his 

 extension of the value of Bernoulli's theorem by the aid of Stirling's theorem. — Prof. Cajori. 



A very full account of the above third edition will be found in Todhunter's History of the Theory of Probability.

' De Moivre's most important work. He demonstrated in it his method of recurring series, created ' imaginary trigono- 

 metry ', through the invention of the theorem known by his name, and generalised Cotes's 'Theorem on the Property of 

 the Circle' (p. 17). Naude's presentation of the book to the Berlin Academy of Sciences produced the election by acclama- 

 tion of its author as a member. Leibnitz, who made de Moivre's acquaintance in London, vainly endeavoured to secure 

 for him a professorial position in Germany ; and his foreign origin similarly barred the way to his promotion in England. 

 So he continued all his life to support himself by teaching, and answering questions on the chances of play and the values 

 of annuities. Yet he was one of the commissioners appointed by the Royal Society in 1712 to arbitrate on the claims of 

 Newton and Leibnitz to the invention of the infinitesimal calculus'.— j¥i«s Agnes M. Clerke. 



11992 MOLESWORTH (Caroline) The Cobham Journals : Abstracts and Summaries of her

 by Eleanor A. Ormerod [Entomologist], roy. 8vo. cL, 4s (p. 105 6d) 1880 



Miss Molesworth was one of the earliest and most Vemarkable of those amateur observers whose labour of love 

 practically founded the science of meteorology in England. Carried on for over forty years at her place at Cobham in 

 Surrey, the observations amounted to over seventy-five thousand, which have been abstracted with the greatest care by 

 Miss Ormerod.
