X.2 for any value of y, agreed very closely witli the observed modal 

 latent period. So assuming that the origin of discharge was at tlie 

 beginning of the stimulus, we calculated as in No. 54. 



The following table shows the constants of tlie curves: — 



Tai'.li: II. 



Oscillogram No. o7. Left organ (whole) of a hsh, the same 



preparation as No. o5 and No. oG. 

 Temperature of the organ: iTC. 



The data and the details of the ol>served ;ui(l the computed num- 

 bers given in the Appendix. 



Here the modal latent pei-iod is tolerably constant as in No. 

 54, having a tendency to increase a little with the progress of the 

 experiment. The constant /r increases with the decrease of the 

 breadth of the stimulus ^"'or the height of the discharge.'"' 



Calculating with these constants the values of y for every one- 

 thousandth of a second, and plotting the values obtained on the 

 reproduced curves, the agreement of the points is very satisfactory 

 as we may see in the figures (Plate VIL). 



* For the sake of brevity, let us call the duration of the stimulating current the Ireadth 

 of stimulus, the maximum intensity of it the heùM of stimulus, and the maximum electromo- 

 tive force of the discharge the heinid of discharge.
