Bath: Printed by R. Cruttwell; for G. & J. Robinson, Pater-noster Row, London, 1801. viii, 413 pages. Together, with LETTERS ON THE ELEMENTARY PRINCIPLES OF EDUCATION. Vol. II. 1802. [4], iv, 455, [1 ad’] pages. Both volumes bound as a matching set in half calf gilt over marbled boards. Octavo. First edition. First edition of both volumes. Volume one being published as a work complete in itself, but then extended by the author with another volume, with an amended title, in 1802. Volume I would appear to have been issued without a half-title. Both volumes have some foxing at start and end; both bear the bookplates of Swansea Training College to the pastedowns; both have the remains of paper labels to the base of the spines.
