8vo. pp xvi, 444, 40. Original cloth, professionally rebacked retaining original spine lettering, a little skewed, endpapers replaced, half title present, interesting catalogue of medical books to rear, library stamps of the Royal College of Surgeons of Ireland to title page, page 1, and 417, occasional a little foxing but overall a clean example. A good example of rather an impressive early work on the relationship between mind and body, dividing his categories into Intellect, Emotion, and Volition in the way that the mind acts upon the physical self. Please note faults. Priced accordingly.
