seasons, and that we only need numerous, and long-continued observa- 

 tions, to know when those peculiarities are likely to recur ? 



P. S. Arguing from what has been to what will be, we might join 

 the two dotted lines in the plate for a conjectural line, the first year of 

 which would be 1836. It would, however, first be necessary to correct 

 the latter part. The two lines of which it is composed 1775, 1779, 

 and 1831, 1835, are both erroneous, as indications of the seasons ; the 

 first in a considerable degree, the latter less so. To illustrate this I have 

 added the line of the Calcutta rain-guage, 1823, 1835, which may be 

 compared with the lines in the plate, Journal, No. 64, and I have other 

 data, which I will arrange and bring forward at a future opportunity.
