^{page 343 note *} In a report upon this treatise submitted to the Board of Manufactures on 17th June 1860, the late Professor Kelland writes:—“Regarded as a book of reference, which shall contain all the more important solutions of the ordinary problems of Practical Geometry, this treatise deserves very high commendation. The constructions adopted by the author seem in all cases to have been well selected; and the arrangement, founded on a classification of results, is eminently adapted to afford facility of reference.”

The Professor, however, reported that, considered as an educational treatise, he did not think its arrangement suitable for the instruction of youth; and the result has confirmed this judgment. As a class-book, Mr Dallas's treatise has been superseded in the School of Art by a much less elaborate and more elementary little book compiled by Mr J. S. Rawle, Headmaster of the Nottingham Government School of Art.
