Eesearcîies on the Discharo^e of the Electric Organ. 23 



Here we sec tliat tlie values of h^ tlius obtained agree in order 

 oi magnitude witii those of No. 37 and No. 40. To prove that our 

 consideration was correct, Ave took Curve No. 7 in No. 54, and 

 using tlie new constants we calculated the values of // for every 

 1/1000 sec. Plotting the calculated values on the experimental 

 curve, we see that they fall so very closely on the ascending 

 l)ranch. that even tlie disagi'cement previously observed at the 

 begiiming of the curve disappears; while the descending branches 

 separate from eacli other widely. The experimental and the 

 calculated curves are shown in Plate IX. Calculating the differ- 

 ences of tlie ordinates of points on the descending l)ranches of the two 

 curves foi- eveiy 4/10000 sec, we have drawn a residual curve 

 whicli would no doubt be caused by the opening-stimulus only. 

 The I'esidual curve thus found is plotted on the same Plate. 

 Having assumed the origin of the residual curve to be at the 

 instant of bieaking of the stimulating current and having found the 

 value corivsponding to .r„ by the formula Xq=^'j:iX.,, Ave calculated 

 the value of //' co]-i-es]ionding to the new curve, and we found that 

 it was e(jual in order of jnagnitude to that (jf the main curve. The 

 constants thus found for the i-esidual curve were .l=]0-0, />'"=:l7-2 

 and .(-,— 100-8. Calculating tlie values of // for eveiy 1/1000 sec. 

 by usiug these constants, and })lotting them on tlie residual curve, 

 we see that the agreement is rather Avonderful. The value of x^ of 

 this curve is a little smaller than that of the main curve, but if Ave 

 consider that tlie effective instant of the closing-stinnilus is a little 

 later tliaii the beginning of tlie stimulus, we have reason to suppose 

 that tlie modal latent ])eriods are equal. 



Tables \. and VI. shoAV the constants oljtained on 

 Oscillograms No. <)2 and No. bo. Avhere broad stimuli are used. 

 Oscillograms No. (*)2. No. 03 and No. 04 (Plate XVI.) form a set of 

 experiments for finding tlie relation betAveen the intensity of the 

 stimulus and the magnitude of the discharge. The breadth of the 

 stimulus is greatest in No. 02, medium in No. 03 and smallest in 

 No. 04. The temperature of the organ Avas ]3-5°C.
