1611 GREEN" (George; Fellow of Caius Coll.] MATHEMATICAL PAPERS, edited by NORMAN MAC- 

 LEOD FERRERS, pr., Master of Caius, 8vo. cl., uncut (VERY SCARCE), 2. 2s 1871 



Including his important 'Essay on the Application of Mathematical Analysis to the Theories of Electricity and 

 Magnetism,' as well as papers on the motion of waves in a canal, and on the reflexion and refraction of sound and 

 light. ' In the latter the geometrical laws of sound are deduced by the principle of energy from the undulatory theory, 

 the phenomenon of total reflexion is explained physically, and certain properties of the vibrating medium are deduced. 

 He also discusses the propagation of light in any crystalline medium'. W. W. R. Ball. 



1642 ESSAY on the APPLICATION of MATHEMATICAL ANALYSIS to the THEORIES of ELEC- 

 TRICITY and MAGNETISM, first edition, 4to. cl., 1. 10s Nottingham, 1823 



VERY SCARCF,, only very few copies having been published by subscription. 



'In this essay he first introduced the term 'potential' to denote the result obtained by adding the masses of all tin 

 particles of a system, each divided by its distance from a given point; and the properties of this function are first 

 considered, and applied to the theories of magnetism and electricity.' D. N. B.

'Gregory St. Vincent is the greatest of circle-squarers, and his investigations led him into many truths: he found 

 the property of area of the hyperbola which led to Napier's logarithms being called hyperbolic. Mpntucla says of him, 

 with sly truth, that no one has ever squared the circle with so much genius, or, excepting his principal object, with so 

 much success. His reputation, and the many merits of his work, led to a sharp controversy on his quadrature, which 

 ended in its complete exposure by Huygens and others.' Prof, de Morgan.

FIRST EDITTOK. ' It was the first textbook composed on gravitational principles, and remodelling astronomy in con- 

 formity with physical theory. Newton thought highly of it, and communicated fur insertion in it (p. 32)his ' lunar theory' 

 long the guide of practical astronomers in determining the moon's motions. The discussion in the preface, in which the 

 doctrine of gravitation was brought into credit on the score of its antiquity, likewise emanated from Newton.' D. N. B.
