1921 HILL (John, Gent.} ARITHMETICK both in THEORY and PRACTICE, made Plain and Easie, 

 with Interest and Annuities, Extraction of the Square and Cube Roots, the Tables and Construc- 

 tion of Logarithms, Arithmetical and Geometrical Progression, etc. etc., third Ed., with several 

 Algebraical Questions, and Preface by MR. HUMPHREY DITTON, sm. 8vo. old calf (some II. 

 stained) ; rare, 15s 1721 



' A work of much celebrity. It seems to have owed its fame partly to a recommendation of Humphrey Ditton, praising 

 it in the strongest terms. Perhaps at this time the only things which would catch the eye are the table of logarithms, 

 and the powers of 2 up to the 144th, very useful for laying up grains of corn on the squares of a chess-board, ruining 

 people by horseshoe bargains, and other approved problems.' Prof, de Morgan, who possessed, however, only the 7th 

 edition of 1745. 



1922 HILL (John, M.D. ; self-styled ' Sir John 1 ) NEW ASTRONOMICAL DICTIONARY, oraCompleat

' For physic and farces, his equal there scarce is, 

 His farces are physic, his physic a farce is.' David Garrick. 

 ' He was very able and very eccentric'. Prof, de Morgan, and he successfully hoaxed the Royal Society.
