liquid increased in bulk. No manifest difference of diffusion appeared 

 during hours in the tube under the anode when compared with 

 that in the tube with no current, excepting that the liquid had risen 

 more in the former than in the latter, probably in consequence of the 

 heat of conduction resistance.

Hxp. 36. — The usual double meniscus apparatus (see p. 58) was now 

 used again, and a single series of twenty-five Grove's elements was 

 employed in this and the following experiments to No. 40. The 

 meniscus tubes were 17 millims. high and 8 millims. bore. Lower 

 and upper liquids same as in last experiment. Copious conduction. 

 Almost instantly a line with strong concavity downwards was pro- 

 duced, about 2 millims. above the blue surface of positive meniscus, 

 and another in the diffused portion of blue liquid below the anode. 

 This was followed by the production of two less- defined lines in the 

 blue portion of solution below cathode, and this was immediately 

 succeeded by a strong wave-like motion at positive meniscus, and a 

 projection upwards of portions of the blue liquid, and soon afterward 

 large bubbles of gas or vapour were produced in the middle part of 

 the positive meniscus in the position of the lowest line. On reversing 

 the current the gas was produced strongly in the meniscus under 

 cathode, and continued a short time also at the other meniscus. The
