A Dudgeons sphygmograph in a black leatherette case, measuring 8.4 x 6 x 6.4 cm. The case is lined in purple silk and velvet, and has a metal snap clasp. The apparatus is made of chrome-plated metal and records the pulse on strips of glazed paper. A grosgrain ribbon holds the instrument to the wrist. The apparatus is in good condition, although a bobbin-like attachment appears to be missing. It was donated by Joseph Leggett Miller in June 1975.
ca. 1890
