the mean of SR. and 4h p.m. as usual. The station is only 10 miles SW. from Madras. —
The place where the instruments had been put up was not quite so well protected against the glare
radiating from the surrounding objects as in the Madras observatory. This may have had some
influence on raising the temperatures a little; but also the circumstance that the station Saint
Thomas Mount was not in quite so free a position as that of Madras certainly is of some in-
fluence.
