MR. J. ZELENY OX THE VELOCITY OF THE IOXS 
These results are represented in curve II. of fig. 13. 
The corrected value of U = 8'48 centims. per second. 
A = 19-16 volts. 
8*48 
o — 5'118 ——rv—. = '749 centim. per second, which reduced to 76 centims. 
3‘02 x 19Tb 1 
pressure becomes '745 centim. per second. 
T = — '36 second.

The results are represented in fig. 14, from which it is seen that the values 
corresponding to T = 0, when corrected similarly to those of moist oxygen, give as 
the velocity in moist carbonic acid, lor the negative ions, 75 centim. per second, and
