No. 1 1 2. Discharge applied for ten minutes only on account of the passage of sparks to the 
plants. This probably caused the increase in carbon dioxide production owing to a large local rise 
of temperature which would be unrecorded.

No. 127. Temperature correction for 2 was large, and would probably account for the differ- 
ence between 1 and 2. 
Nos. 127 and 128. Electrification 30 minutes. 
No. 129. Electrification 15 minutes. 
No. 130. Electrification 5 minutes.
