Thus even with only one Grove, under favourable circumstances, 

 irreciprocity of conduction shows itself for short closing, whilst for 

 long closing it is only very feebly pronounced, so that in the 

 corresponding experiment of the first series, it was not perceived at 

 all.

The heating of the preparation prevented further observation ; 

 the irreciprocal conduction nevertheless makes itself noticeable in 

 the series of differences. 



The last experiment of the appendix of the first communication 

 (25) is allied to these experiments, as being of similar inter- 

 pretation. There, the current strength in the circuit of a battery 

 of twenty cells closed through a preparation, and at the same time 

 in a side circuit, by which the preparation was bridged, was 

 observed. For short closing, the irreciprocity was very great ; 

 if the closing lasted one second, it was already disproportionately 

 feebler. 



13. Of the law and the nature of irreciprocal conduction 

 in the electrical organ. 



In accordance with the preceding, there can be no doubt, that 

 irreciprocity of conduction is disproportionately greater for short 

 closing of a battery and for opening shocks of an inductorium, than 



1 Here, instead of 45 turns at zero distance, 5000 turns were used at a distance of 

 30 mm. The deflections are diminished in the ratio 45/5000, and are reduced to 

 the distance zero of the coil (comp. 454).
