In the experiments of Valentin' a temperature of 250 0. was sufficient to produce these movements. Valentin also observed that the movements produced by a temperature of 450 were much feebler than those produced by a temperature of 25°.In the author's experiments water was heated in a copper vessel, in which was kept a thermometer, and the temperature obtained noted. The frog was supported at the middle…
