A Course of Lectures in Natural Philosophy

Stated Second Edition, bound in calf leather, gilt lettered title over red Morocco leather in one spine compartment. Richard Helsham, M.D., was also a Professor of Physics and Natural Philosophy in Dublin, Ireland and, at the time, a contemporary of and friend to the likes of Jonathan Swift.

Printed for J. Nourse, at the Lamb, without Temple-Bar. Bound in scuffed and rubbed leather, protected in stiff plastic, but the front board is nearly detached, holding on by two threads. Upper joints cracked a bit, rubbing to, scuffing of spine head and foot. Red-speckled fore- and bottom-edges, top-stained in red. Five raised bands to spine of this octavo format text, red and black lettering to title page. Generally clean interior, a few dog-eared pages.
