Dealinj; with an episode in Newton's life little referred to by his biographers, but characteristically mentioned by 

 Voltaire : his relations with Charles Montagu, first Earl of Halifax, his friend and political patron, and his niece Cathkrink 

 Barton, afterwards Mrs. Conduitt, who was Montagu's mistress. The work contains new evidence which quite clears 

 Newton from a charge of connivance in his niece's easy virtue.

 First Publication of Sir Isaac Newton's Principia, with diagrams, 8vo. c/., uncut 

 (scarce), \0s 6d Univ. Press ^ Oxford, 1838 



The name of Stephen Peter Rigaud will be familiar to Old Westminsters as that of the father of Stephen Jordan 

 Rigaud, whose House in Little Dean's Yard is still known by his name, and who died of yellow fever in the West Indies' 

 within a year of his consecration to the Bishopric of Antigua. Professor Rigaud himself was a capable astronomer, but 

 was still more remarkable for his accurate knowledge of the literature and history of the subject, and as a mathematical 

 antiquary and bibliographer with no rival previous to de Morgan. It is to him that, in the first instance, we owe much 

 of our information about Newton and the history of his discoveries. 'The Historical Essay is an admirable exposition of 

 the facts then known, and contained much new and interesting matter about Halley, whose life Rigaud intended to 

 write'.— i). N. B. 



The appendix contains : I. Newtoni Propositiones de Motu : Early Notice on Fluxions (from an original paper in 

 Newton's handwriting), Newton and Huygens, On the Cause of Gravitetion, Halley's Review of the Principia, Unpub- 

 lished Correspondence, etc.

 large 12ino. hf. bound (joints broken) ; rare, 10.s Qd 1747 



' Robinson was an ardent admirer of Newton, and tried to account for animal motions by his principles, and to apply 

 them to the rational treatment of diseases. He attributed the production of muscular power to the vibration of an 

 ethereal fluid pervading the animal body, a doctrine essentially in accord with modern views.'— i). N. B. He attempts 

 to prove that ' iether causes gra\ity by giving bodies a mutual tendency to one another.'

 8vo. old calf, 12^5 1738 



'The story that this train of thought [on gravitation] was aroused by seeing an apple fall is due to Voltaire, and is 

 given in his ' Philosophic de Newton' . Voltaire had it from Newton's step-niece, Mrs. Conduitt. For many years 

 tradition marked the tree in the garden at Woolsthorpe : it was shown to Sir David Brewster in 1814, and iras taken 

 down in 1820.'— D. N. B.

Rare, and unknown to the author's biographer in D. N. B. The second part, ' the Principles and Properties of 

 Material Motion ', appeared in an enlarged form in 1764. The work is not noticed in Gray's Bibliography of Newton. 

 The introduction is strongly anti-Newtonian.
