The anemometer is by Casella, and is a Robinson’s, as 
improved by Col. Sir Henry James. 
To ensure correctness as far as possible, every instrument 
has been carefully tested both before being placed and also 
afterwards; and they are all read by Mr. Bates every morning 
at nine o’clock, and in his absence by his schoolmaster ; and 
that their readings may be as much as possible alike, they 
often read them together for the purpose of comparison. 
The monthly amounts of rain received by the different 
o-auoes and the movement of the wind are shown in the

From these results it appears that in every month of the 
year, and with both sets of gauges, the highest gauge received 
the least amount of rain ; and that the 8 inch Glaisher 
gauges received slightly greater amounts than the corre- 
sponding 5 inch Howard’s. The movement of the wind was 
greatest in March and least in August. No relation appears 
to exist between the monthly amounts of rainfall and the 
monthly movement of the wind. 
NOTE BY MR. BAXENDELL. 
The differences between the amounts of rain received by 
gauges placed at different elevations at the same station, are
