the previous experiment. Both nerves were then prepared and connected alternately 

 with the galvanometer in the manner already described. The excitatory electrical 

 effects in each nerve following the stimulation of the different columns of the cord 

 were observed with different intensities of stimulus, and the results, which are 

 analogous to those obtained in the Cat, are shown in the following Table. The left 

 nerve was found to be less excitable than the right, but the resting difference of both 

 was 005 D.
