The Interval between the Pulses, taking 1880 as the Central Year, 

 on the Upward Curve. 



1880, Madras famine. 



N. W.I', famine. 



1880-11 = 1869, N.W.P. famine (1868-9). 

 1869-11 = 1858, N.W.P. famine (1860). 

 1858-11 = 1847. 



1847-11 == 1836, Upper India famine (1837-8). 



(Great famine.) 



The Interval between the Pulses, taking 1885-6 as the Central Years, 

 on the Descending Curve.

It is clear from the above table that if as much had been known in 

 1836 as we know now, the probability of famines at all the subsequent 

 dates indicated in the above tables might have been foreseen. 



The region of time from which the above results have been obtained 

 extended from 1877 to 1886. The next table will show that if the 

 dates, instead of being carried back, are carried forward, the same 

 principle enables us to pick up the famines which have devastated 

 India during the period 1886-97. 



Same intervals, going Forward.

 1885-6. 



+ 11 1896-7, General famine. 



This result has arisen, so far as we can see, from the fact that the 

 + and - pulses included in the period 1877-1886 were normal ; that 

 is, were not great departures from the average.
