Another piece of hard-drawn iron wire, of the same diameter and 
same length as before, was put into the bath for one whole day. 
When the wire was taken out, it was carefully dried and wiped. 
In this case, the original weight of the wire was 0‘2170 grammes 
and the weight after the occlusion was 0’2192 grammes, so that 
there was an increase of weight to the amount of 2*2 milligrammes. 
This being assumed to be due to the hydrogen occluded, corresponds 
roughly to a volume of gas (at atmospheric pressure) of 25 cubic 
centimetres, or 790 times that of the wire. The original resistance 
was 4437 ohms at 24° *7. After the occlusion the resistance was
