It was natural that the great Indian famine, occurring at a time
when sun-spots were nearly at a minimum, should by some be directly
associated with a deficiency of sun-spots. In this country, indeed,
we have had little reason, during the last two or three years of few
sun-spots, to consider that drought is one of the special consequences
to be attributed to deficient solar maculation. But in India it may
be different, or at least it may be different in Madras, for it has
been satisfactorily proved that in some parts of India the rainfall
increases in inverse, not in direct proportion, to the extent of
solar maculation. Dr. Hunter has shown to the satisfaction of many
that at Madras there is “a cycle of rainfall corresponding with the
period of solar maculation.” But Mr. E. D. Archibald, who is also
thoroughly satisfied that the sun-spots affect the weather, remarks
that Dr. Hunter has been somewhat hasty in arguing that the same
conditions apply throughout the whole of Southern India. “This hasty
generalization from the results of one station situated in a vast
continent, the rainfall of which varies completely, both in amount and
the season in which it falls, according to locality, has been strongly
contested by Mr. Blanford, the Government Meteorologist, who, in making
a careful comparison of the rainfalls of seven stations, three of which
(Madras, Bangalore, and Mysore) are in Southern India, the others
being Bombay, Najpore, Jubbulpore, and Calcutta, finds that, with the
exception of Najpore in Central India, which shows some slight approach
to the same cyclical variation which is so distinctly marked in the
Madras registers, the rest of the stations form complete exceptions
to the rule adduced for Madras, in many of them the hypothetical
order of relation being reversed. Mr. Blanford, however, shows that,
underlying the above irregularities, a certain cyclical variation
exists on the average at all the stations, the amount, nevertheless,
being so insignificant (not more than 9 per cent. of the total falls)
that it could not be considered of sufficient magnitude to become a
direct factor in the production of famine. It thus appears that the
cycle of rainfall which is considered to be the most important element
in causing periodic famines has only been proved satisfactorily for
the town of Madras. It may perhaps hold for the Carnatic and Northern
Siccars, the country immediately surrounding Madras, though perhaps,
owing to the want of rainfall registers in these districts, evidence
with regard to this part is still wanting.” On this Mr. Archibald
proceeds to remark that, though Dr. Hunter has been only partially
successful, the value of his able pamphlet is not diminished in any
way, “an indirect effect of which has been to stimulate meteorological
inquiry and research in the same direction throughout India. The
