472 LIVING TORPEDOS IN BERLIN. 



The experiments with a short closing time were merely a repetition 

 of the foregoing series, and serve to show that the preparation was still 

 in a condition of activity. The deflections of the galvanometer (P) with 

 the longer closing time correspond well with those obtained in series 8, 

 in which only 10 Groves were used arid the closing time was the same. 

 The increase of the deflections as the experiment proceeded depended 

 on the heating of the preparation. The deflections due to negative 

 polarisation are remarkably large in the last half of this series.

The remarkable phenomenon which presented itself here, viz. the very 

 slow development of the absolutely and relatively positive deflection (*), 

 was obviously caused by the considerable diminution of negative polar- 

 isation, which however did not in this case occur with sufficient rapidity 

 to give occasion for a deflection in successively opposite directions.
