AN ESSAY ON ORNAMENTAL DESIGN, IN WHICH ITS TRUE PRINCIPLES ARE DEVELOPED AND ELUCIDATED, &c.

_From the Athenæum._

In conclusion, Mr Hay’s book goes forth with our best wishes. It must be good. It must be prolific of thought—stimulant of invention. It is to be acknowledged as a benefit of an unusual character conferred on the arts of ornamental design.

_From the Spectator._

Mr Hay has studied the subject deeply and scientifically. In this treatise on ornamental design, the student will find a clue to the discovery of the source of an endless variety of beautiful forms and combinations of lines, in the application of certain fixed laws of harmonious proportion to the purposes of art. Mr Hay also exemplifies the application of his theory of linear harmony to the production of beautiful forms generally, testing its soundness by applying it to the human figure, and the purest creations of Greek art.

_From Fraser’s Magazine._

Each part of this work is enriched by diagrams of great beauty, direct emanations of principle, and, consequently, presenting entirely new combinations of form. Had our space permitted, we should have made some extracts from this “Essay on Ornamental Design;” and we would have done so, because of the discriminating taste by which it is pervaded, and the forcible observations which it contains; but we cannot venture on the indulgence.
