During twenty of these years simultaneous observations were taken at the Apart- 
ments of this Society. The following Table of comparison of results is formed by 
comparing the numbers in the preceding Table with those for the same months in 
Table 1. of my paper in the Philosophical Transactions, Part II., 1849.
