It will be seen that heat was the predominant feature of 

 this series, and this was followed by storms, with heavy 

 rains and floods. The winters were very cold, the rivers 

 being sometimes frozen. 



I have prepared tables of historical events, as complete 

 as it has been possible to make them, during the three 

 periods 1756 to 1767, 1813 to 1824, and 1870 to 1881 (which 

 are at 57 year intervals) and at 171 year intervals from 

 each of the periods back into the past. These tables afford 

 a means of comparison, but are too voluminous to be 

 printed with this paper. They are, however, available to 

 anyone desiring to sat isfv himself that the conditions are 

 similar, as I have stated, although varying in intensity. 



fn the first series, commencing from 1756 to 1767, it will 

 be seen that it is remarkable for the intense cold of the 

 winters. In the second series, commencing from 1813 to 

 1824, the great heat of the summers is noticeable as already 

 referred to; while in the third series, commencing from 

 1870 to 1881, the intensity and violence of the storms with 

 excessive rain, causing high floods, are the prominent 

 features. 



Similar tallies have been prepared for the periods 1776 

 to 1785, 1833 to 1842, and 1890 to 1899 (which are also at 

 57 year intervals), and at 171 year intervals therefrom. 

 These will be found to be extremely interesting, as they 

 show the character of the weather at the critical points of 

 change in the Nile's curve, viz.: at 1782, 1839, and 1896. 



Drought and Famine in India.- In default of any reliable 

 rainfall statistics extending over a period sufficiently long 

 to enable a residual mass curve to be constructed which 

 might fairly be compared with other long records available, 

 I have considered it advisable to show the years of drought 

 and famine, which have been collected from reliable sources, 

 in their proper places on the diagram by means of black
