immersion in boiling water.) The result gave the thermometer 0 degree

point 80 too much at the boiling-point.

Table No. 1.—In this Table the error obtained at Kew Observatory has

been treated like that of a chronometer, the error being assumed

increasing and regular.

Table No. 2 is to correct the height, computed by Mr. Dunkin, using the

quantity taken from Table No. 1.

Table No. 3 is the final result of the observations for height,

corrected for instrumental error.
