The elements of Euclid : viz, the first six books, together with the eleventh and twelfth : the errors, by which Theon, or others, have long ago vitiated these books, are corrected, and some of Euclid's demonstrations are restored : also, The book of Euclid's data, in like manner corrected
Robert Simson's edition of Euclid's Elements — books one to six, eleven and twelve, plus the Data — reprinted in Philadelphia by Desilver & Thomas in 1834 as a school and college geometry text. The 258 pictures are small letterpress line diagrams: circles crossed by chords and radii, inscribed triangles, tangents and angles, each vertex lettered in serif capitals, useful as abstract geometric marks.
