 of the present day, scarcely a work has been accomplished but it is fully described and carefully illustrated here.'

'His fame rests chiefly on his 'Theorie de la Figure de la Terre ', in which he promulgated the theorem that the 

 variation of gravity on the surface of Ihe earth, regarded as an elliptic spheroid, was altogether independent of the law of 

 density'. He develops in this work the first theory of capillary attraction, and first gives the differential equation, till 

 then unknown, of the equilibrium of fluids, supposing an attractive force, following any law whatever, to exist among the 

 molecules. 



' In the figure of the earth no other person has accomplished as much as Clairaut, and the subject remains at present 

 substantially as he loft it, though the form is different.' Todhunter.

' To JOHN CAMPBELL [LL.D., 1708-75] has been generally ascribed the recast of ' The Shepherd of Banbury's Rules '. It is 

 somewhat noticeable as an attempt to base on quasi-scientific principles the weather forecasts of the alleged Banbury 

 shepherd.' J>. X. B. See also Notes and Queries, I. Ser., VII. v. 373.
