The rise in the curve at 1.32 corresponds with the appearance 
of clouds, the fall at 3.25 with unclouded sun : but these 
changes in the weather are not apparent in the temperature 
curve. It should be noted that between 10.20 and 12 the 
plant was much disturbed in testing the balance. This sort 
of disturbance generally causes a fall in the curve — why, 
I cannot say.
