- Kennelly's Physiological Experiments. Took the Carpentier D'Arsonval galvanometer, and a Wheatstone Bridge to the Phonograph Works and set them up in the Testing Room thre. Used four phonograph cells of the chromic acid type. Filled up two Callaud glas jars as in the preceding test with a solution of crude KHO of density 1:10 and changed the solution in the afternoon. Each man washed his hands & dried them before immersing them pointing verticallly downwards in the jars until the tips of the fingers rested on the bottoms. The bridge ratio was 1000/1000 no shunt capable of reading to single homs and observation was made to [im?] f.z. The current was applie on the average for about thirty seconds. The surface of the solution reached as a rule the pulse of the wrists.
