Guntoor.
of the town of Guntoor, who occupy the only wide and dry street in it, almost entirely escaped the
disease ; while the Brahmins, who inhabit a close and damp street, suffered
in as great a proportion as any other class of the people.
Nellore District.
In the most northerly villages of the Zillah of Nellore this disease began to prevail on the 2nd of
August; and before the 5th of October it had reached the most southern part
of it, having in its course appeared at the town of Ongole on the 14th of
August, and at the town of Nellore on the 20th of September. The Zillah extends about 180 miles
from north to south, and varies between forty and sixty miles from east to west. In twelve days it
travelled thirty-two miles, in the next twenty-seven, eighty more ; and in two months from its com-
mencement it spread over the whole Zillah, except the two south-west divisions of it, which altogether
escaped this visitation. These are the most elevated parts of the Zillah; they are populous and much
frequented by merchants. The disease indeed was less fatal than in the other parts in the whole
western frontier, which is near the hills ; and in some of the villages there situated, it did not at this
time appear. There had been no sensible change in the atmosphere previously to its approach, nor
was its progress at all affected by the occurrence of the rains. It continued during the rainy season;
and, disappearing in the order in which it had commenced, it entirely quitted the Zillah before
the 15th January 1819 ; it again became general in the northern parts of the Zillah about the
middle of April 1819, and continued to travel in a southerly direction, at nearly the same rate as
formerly, having reached Ongole on the 16th of May and Nellore on the 3rd of July. In the Ongole
District it disappeared before the end of August, and in that of Nellore before the end of September.
The period of its continuance in any large town or tract of country of these districts scarcely ever
exceeded three months. At this time it was more prevalent and much more fatal than last year ;
and it was especially violent at those places which then enjoyed an immunity. The weather was mild
and tempsrate during the whole period of this second attack. There were occasional falls of rain,
but no change in the sensible properties of the atmosphere seemed to affect the course of the disease.
Madras.
At Madras the first case seen by a Medical Officer occurred on the 8th of October ; but, from the
accounts of natives, it then appeared that some cases had occurred so early
as the 5th of that month- It continued to prevail pretty generally in Madras
and in the adjacent villages until the 24th, when it received a temporary check from a violent storm
that happened on that day. It very soon, however, increased again, and prevailed with a consider,
able, though variable degree of violence until the beginning of November. It then began to decline
slowly ; and sometime afterwards it became milder and of rare occurrence. The poorer classes
suffered more from its ravages than those in better circumstances. A detailed account of the state
of the weather, during the prevalence, will be found in the meteorological tables. On the 5th the
wind was southeasterly, the weather cloudy and wet, and there was much thunder. On the 7th
the wind became north-westerly, and it continued in this direction until the 12th; from the 12th to
the 15th it was variable. The weather was cloudy, and much rain fell from the 5th to the 15th ;
from the 15th to the 23rd the wind was with little variation south-easterly, and the weather generally
pretty clear. The north-easterly wind commenced on the 23rd, and the violent storm, already
noticed, occurred on the 24th. The weather, though variable, was pretty frequently clear after this
period. In April 1819 the troops at the Presidency were entirely free of the disease, but it re-ap-
peared early in May ; and, although it did not afterwards become general, it has continued to show
itself occasionally since that period. Its attacks were most frequent during the hot months of 1819
and 1820 ; in 1821 they have been of more rare occurrence.
Poonamallee.
It appeared at Poonamallee on the 13th of October ; and without having become very prevalent
seems to have disappeared about the middle of the following month. From
the 8th to the 21st of July 1819 many cases again occurred at this place.
St Thomas' Mount.
At St. Thomas' Mount also it appeared on the loth of October ; but, although not very violent or
general it continued long at this station. It declined considerably in
December, and continued to decrease until May 1819. It again increased in
May ; and, during the three subsequent months, was more prevalent than at any preceding period
of its course. It declined in September, and early in 1820 became of rare occurrence.
Wallajahbad.
It first showed itself at Wallajahbad about the middle of October, and continued to prevail with
different degrees of violence in H. M.'s 86th Regiment and among the
Native inhabitants during November and December. Several cases occurred
there about the end of April, and a few in the beginning of May 1819 : it became provalent towards
the end of June of that year, especially in H. M.'s Royal Scots ; declined. about the 8th of July, and
soon afterwards disappeared.
