A Davis and Kidders patent magneto-electric machine for nervous diseases, patented in 1854. This is probably a later model. The machine is housed in a wooden case with brass crank handle. A printed label with manufacturers information and operating instructions is pasted to the inner lid. The machine was donated by J.B.V. Butler, M.D., in April 1953. The printed label is torn and the key is missing, but otherwise the item is in fair condition. It measures 25 x 11 x 11 cm.
