16. The hygrometer showed a mean difference between the dry and wet
bulb of 25° at 10 a.m. and 31° at 4 p.m. for the 10 days, including the date of
the outbreak. On this point there are no data for comparison with former years.
17. The prevailing winds for the 10 days were W, SW, and NW.,
with a mean velocity of 98 miles in the 24 hours. At this time of the
year the wind blows with the greatest velocity between the hours of 10 and 4« ;
the nights are usually calm or the wind is very light.
18. The rain-fall registered at the principal stations in the different
months in the year and the average of former years within the epidemic area is
shown in a separate Statement. The latest fall registered at Seonee and Luckna-
down, distant respectively 27 and 9 miles from Gunneshgunj, the locality in which
cholera first broke out, occurred between the 23rd and 25th March, when rather
more than an inch fell at both places ; from this time to the end of May there
was an almost total absence of rain over the districts of Seonee, Mundla, and
Jubbulpore above the ghats.
19. The general health of the labourers prior to the outbreak of cholera
is reported to have been good. Unfortunately the systematic registration of
deaths in the Seonee district is confined to the Sudder Tehseelee, and this does
not include the locality where the first outbreak of epidemic cholera occurred.
In the monthly returns from this tehseelee, however, which contains 574 villages
with a population of 155,000, 78 deaths from cholera were registered in the 9
months preceding April 1868. They were reported as follows : —

20 Again in the returns from the Burgee Police circle, in the Jubbul-
pore district, but still in the trap formation south of the Nerbudda and traversed
by the road, 6 deaths from cholera are returned in January and 6 in February.
In these instances the deaths happened in villages on the road, and one is
reported from Hoolkee, where the second outbreak among the coolies subse-
quently occurred.
All these cases were reported by the village Kotwals to the Police. That
all or any of them were truly cases of cholera cannot be affirmed with certainty ;
it is, however, necessary that their occurrence should be taken into account when
the origin of the epidemic is under consideration. It is, moreover, worthy of
note that out of 12 Police circles in the Jubbulpore district, many of them of
"much wider extent, deaths from cholera appear in the returns from the circle of
Burgee only, within which the second outbreak of cholera occurred, and the geolo-
gical formation of which is the same as that of the locality where the disease
first assumed an epidemic form.
21. The first outbreak of cholera occurred in a body of Purdessee coolies
in the Gunneshgunj valley, 57 miles from Jubbulpore and 28 from Seonee. For
