This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ...who had lost his hand in the service of his country.--See Nota and Queries for July 17, 1867, p. 35. ARTIFICIAL LIMBS.
