On the Causes and Treatment of Impediments of Speech; including the theory of articulate sounds, and on the construction of hearing and speaking instruments.

London: John Churchill… 1856

8vo, pp. v, (i) blank, (3)–18, (vii)–viii (contents), [9]–79, (1), lithographed frontispiece, + Churchill’s 32-page catalogue at the end. Title is a cancel. Original brown cloth (a little rubbed and damp-marked, foot of spine worn and small nick in fore-edge of lower cover).

First edition under this title, but this book is a reissue of his On articulate sounds: and on the causes and cure of impediments of speech (1851) with a cancel title and the addition of the 18-page essay on speaking instruments at the beginning. It was considered remarkable for its careful examinations and for the mathematical demonstrations given of each theory advanced (ODNB). Bishop was a distinguished surgeon, being a member of the Royal College of Surgeons, president of the Medical Society of London, and a fellow of the Royal Society. This title is surprisingly rare, with only two copies recorded in COPAC.
