There was a time in my own struggling for artistic existence, when I should have been so grateful for any practical teaching in orna ment, that I fancy there must be students who will find it helpful to have set plainly before them what I have had to puzzle out for myself. Hence this series of Text Books of Ornamental Design; in which I have amplified and illustrated the substance of a series of Cantor Lectures delivered in December last before the Society of Arts.
