about two miles from Newcastle, where he remained some 

 years; during which he improved himself by close studv, 

 reading all the mathematical and other books he was ab!c 

 to pnrchasc. 



About the year 1760, Mr. Hutton removed to Newcastle, 

 where he had a better opportunity of displaying his talents 

 to advantage, and where lie gave extraordinary proofs of 

 the progress he had nriade, by the solution of several curious 

 and difficult questions in various periodical publications; 

 and particulaily in the Ladies' Diary, in his own name, and 

 in Martin's Magazine of Sciences, under the signature of 

 Toiithu, being the letters of his name transposed. The 

 first of Mr. Hutton's separate publications was a little work 

 on arithmetic, for the use of schools, first printed at New- 

 castle in 1764. It has already gone throush ten larsre 

 editions; and in printing the first, to supply^'the want of 

 proper mathematical types, which at that time could not 

 be procured in Newcastle, Mr. Hutton was obliged to cut 

 with a pen-kniie, on the reversed end of old types, many 

 of the algcljraical characters used in the vulgar fractions 

 and other parts of the work. 



Mr. Hutton employed his evenings in composing a laroc 

 ■work on mensuration, which came out in quarto numbers, 

 the last of them in the year 1 770. It was printed at New- 

 castle. This work met with a very favourable reception, 

 and a second edition, with improvements, was published at 

 London in 1788, large octavo. Mr. Ilutton soon gave 

 another proof of his genius and industry, by a republieatiou 

 of all the useful parts of the Ladies' Diaries, from the com- 

 mencement in 1704 to that of 1773. 'i his work was given 

 to the public, in parts or numbers, quarterly, beginnino- in 

 July 1771, and ending in .July 1775, forming altogether 

 five voliuTies, viz. two volumes of the poetical parts, and 

 three of the mathematical. These extracts were accom- 

 panied with nwmerous notes and illufitrations, which sup- 

 plied the defects in the original solution of the questions. 

 Each number contained also a few sheets of new mathema- 

 tical correspondence, of original essays, questions, 8cc. 

 making one volume, in which the contributions of the 

 editor himself made a considerable portion, but under 

 various fictitious names. About the years 1771 and 177i?, 

 Mr. Hutton was employed by the magistrates of Newcastle 

 to make an accurate survey of the town and eountv of New - 

 castle-upon-Tyne, which he did with great cc: rectness. 

 This plan was soon after engraved and published in a map
