EPIDEMIC CHOLERA. OF INDIA OF 1875 AND 1876.

[Section IV.

        The cholera which appeared in Oudh ran parallel with the revitalisation of the cholera of
Goruckpore and Busti in 1875, after taking into account that 50 deaths, out of 56 registered
in February, occurred in the extreme south of the province*:—

                                  Cholera Deaths of Oudh, January to August 1875.

        The parallelism in ratios is shown thus:—

                      Died in each Month out of the Total Mortality from March to August.

       In this aspect, the cholera of Oudh appears as a revitalised cholera, and not as the cholera
of a new invasion distributed over the province from 15th February onwards.

     The appearance of cholera was delayed until April in one district only of Oudh. Hurdoi
is the most westerly district of the province. The first case, after a lapse of 11 months, occur-
red on 11th April, just as in Bundelkhund and Agra; and within three days four subdivisions
of the district were affected.

       The appearance and growth of the
cholera in Upper and Northern India
in the spring.

       In the whole of the area of the North-Western Provinces, 35 deaths were registered
in January 1875. In February the deaths rose to 160, 15
in the western districts and 145 in the eastern. In March
there were 1,100 deaths, 42 in the western and 1,058 in the
eastern districts, which are associated with Oudh in physical
and meteorological characteristics. Northern India still remaining unaffected, the deaths of
the North-Western Provinces in April were 6,031; but out of this large total the deaths of
the western half of the province were, in April, still under 100. The tendency to the
appearance of the epidemic over a wider tract was, however, shown by the occurrence of
cholera at Banda and Hamirpur—a link connecting the spring cholera of the east, with the
spring cholera of the west; the cholera of 20th April spread over the western area from
Dehra Dun to Sholapore.

     Growth of cholera in the early
spring area of the Central Provinces
in the first quarter of 1875.

       Raipore and Belaspore are the only districts of the Central Provinces in which we find cholera.
localised in the first quarter of 1875. This eastern division of
the Central Provinces gave for the year 7,228 deaths¸ out of a
total for the province of 14,456; and these early deaths were true
forerunners of the cholera which became epidemic in May and
culminated in July and August.

       In accordance with previous experience, cholera was not conveyed out of this area into
the districts of the Central Provinces lying to the west.

     The growth of the spring cholera
of Madras and Bombay of 1875.

       This was the manner in which the cholera of the districts of Bombay invaded in the
spring progressed. The deaths of the Gangetic districts rise and
fall naturally from March to August; those of the early dis-
tricts of Bombay, from April to September—

       The homologous phenomenon, which is entirely a natural one, was thus exhibited in
Southern India, in the Tanjore district, which got its cholera in the same week:

    All throughout India the mani-
festations of spring cholera in 1875
were links in one common chain.

       These general statements exhibit to us nearly every province of India linked in one
week by a common chain, extending from the Himalayas to
the extreme south of the continent. The dates are not for-
tuitous, nor are they brought together to patch up a theory.
It is the simple statement of a great truth, that, after having.
disappeared for two years, in the third year cholera re-appeared in the same week from one
extremity of India to the other.

       *The dates given are—Partabghur 19th, Rae 13areli 17th, Sultanpur 28th February. Cholera appeared at Fyzabad
on 16th February; and 5 deaths, out of the 6 remaining, occurred before the end of the month.
