Medical, for their ready aid in furthering my special inquiry, and to the
Medical Officers of the 18th Hussars, Drs. Scott and Anderson, I am indebted
for much valuable information, as to the progress of the epidemic in the Hussars.
Cholera history of
the neighbourhood.
7. In considering the peculiarities of the local cholera outbreak at Secun-
derabad, it is absolutely essential that the condition of the
neighbouring territory in regard to cholera, should be noted,
for it is I believe absolutely true, that no localised cholera ever occurs which
has not a defined place in a general epidemic movement of the disease.

part of 1868 and beginning of 1869, when a great cholera
wave moved southward from the Central Provinces over a
large portion of the Peninsula of Southern India. This cholera was very fatal in
the city of Hyderabad and in the Secunderabad bazaar, but the European Troops
escaped with but few cases, and 110 case whatever occurred in the Hussars.
9. This epidemic disappeared finally from Secunderabad about August 1869,

and from that time up to the date of the recent outbreak, not
a case of cholera had been known to occur anywhere within
one-hundred and fifty miles of the cantonment. A death from cholera was
reported at Trimulgherry in 18TO, but the history of the case made it very
doubtful, whether the death had been correctly described.

10. The epidemic of 1869 passed on gradually to the extreme south of the
Peninsula. In the cholera report for 1870, I have shown, in
detail, the progress of the epidemic in the Southern Provinces.
At the end of 1870, there was cholera in the Trichinopoly,
Coimbatore, and Malabar Districts ; and early in January 1871, there was an
indication of an oscillation of the cholera wave of the south,
that is, after occupying the extreme south of the Peninsula
and Ceylon, it began to travel northwoards again along the
Western Coast, and also in the centre of the Peninsula.
Cholera in Kurnool
District in January 1871.
11. This northward movement of cholera, especially in the districts which
had been newly invaded from the north in 1869, was observ-
able in several directions about the same time. In January
some pilgrims returning to Hyderabad from Trichinopoly, where cholera was
prevailing, suffered an attack in the Kurnool District, and some villagers who had
been brought in contact with the pilgrims took the disease and died, but the
outbreak in this case was confined to three small villages of the Kurnool District,,
and the disease did not spread beyond them.
Outbreak at Calastry
in February during a
festival.
12. In February cholera broke out in a severe form at Calastry, in North
Arcot, during a festival held there. From this focus it cer-
tainly spread to the town of Cuddapah, where in March and
April it caused 320 deaths.
13. The evidence regarding the introduction of cholera into Cuddapah from
Calastry is recorded at page 87 of my Proceedings for February and March 1871.
Extension of
the
disease
northward
through Nellore and
Kistna Districts in April
and May 1371,
14. The epidemic spread northwards also through the Nellore District and
especially in the towns and villages along the great northern
road. I have had a sketch map of the districts prepared, show-
ing some of the principal places at which cholera appeared
during April and May. The spelling of the native village
