DR. W. A. BONE AND MR. R. V. AVHEELER ON THE COMBINATION OF 
impossible to remove it in places where the strands of wire overlapped) with a chamois 
leather, and subsequently re-determining the rate of combination for normal gas in the 
two following experiments :—- 
Experiment VIII. 
September 20, 1904. 
Normal electrolytic gas. T = 400°. Rate of 
circulation = 1 in 65 minutes. 
Experiment IX. 
September 21, 1904. 
Normal electrolytic gas. T = 400°. Rate of 
circulation = 1 in 65 minutes.

In the next experiment, a mixture initially corresponding to 3H 2 + 0 2 , nearly, was 
employed. The residual hydrogen was subsequently circulated over the gauze at 
400° for 16 hours, after which it was pumped out, and the rate for “normal” 
electrolytic gas re-determined (Experiment-XI.). 
Experiment X. 
September 21, 1904. 
Electrolytic- gas plus excess of hydrogen, 3H 2 + (X T = 400° 
Rate of circulation = 1 in 65 minutes.

The results of Experiment X. confirm those of the corresponding experiment of the 
previous series (Experiment V.) with the mixture 3H 2 + 0 2 . Up to a certain condition 
of maximum “ hydrogenation,” the rate of steam formation largely depended on the 
partial pressure of the hydrogen, afterwards, however, on that of the oxygen. In
