It seems unlikely that the actual values of the electrical quantities 

 should be much lower than those given in the table. The voltage meas- 

 ured with the external circuit open sets a lower limit to the possible 

 value of the electromotive force. The maximum measured voltage is, 

 on the average for all the specimens, 77 per cent of the value found for 

 the electromotive force. It seems reasonable that the current in cir- 

 cuits closed in the body of the fish should cause a voltage drop of 23 

 per cent. Similarly, the charge passing through the external resist- 

 ance, which is obtained directly from simple oscillographic measure- 

 ments, sets a lower limit to the possible magnitude of the charge tra-
