 ' Dissertation on the Sacred Cubit of the Jews, trans, from the Latin of Sir Isaac Newton, not yet published,' etc., etc. 

 The author was besides one of the most learned Orientalists of the day and a great Eastern traveller and collector of 

 MSS., all with a view to the study of mathematics. He was a friend of Abp. Laud, and Sub- Warden of Merton, from 

 which office and his Professorship he was expelled by the Parliamentary visitors in 1048, with the loss of nearly all 

 his libi-ary.

IncludinR 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 geom-'trical laws of sound are <leduced by the principle of energy from the undnlatory 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'.— IK. W. R. Ball.

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

 particles of a system, each dividt-d 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.'-—!). N. B.

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

 the property of area of the hyperbola which led to Napier's logarithms being called hyperbolic. Montucla 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 Huygcns and others.'— Prof, de Morgan.
