Old Jumna River.—The hsematozoa were found to be swarming in one specimen, few in a second,
and absent from the blood of seven.
Grisauli or Girai (Punj), Murral (Hindustani).—These fish belong to the order Acanthopterygii *
family Ophiscephilidde; genus Ophiscephalus; species 0, Striatus.
Depot Pond.—A large variety of hæinatozoon was present in the blood of six specimens of this
species of fish examined.
Old Jumna River.—The large variety of hæmatozoon was found in the blood of three fish examined.
Singhi or Tinghi.—This fish belongs to the order Physostorii; family Siluridæ; genus Macrones ;
species M. Seenghala and M. Tengara.
These fish were caught only in the Old Jumna River, but were not seen in the West Jumna Canal,
or in the neighbouring ponds. The small variety of the hæmatozoon was found in the blood of all the
specimens examined; they never exceeded five in a field of the microscope, Zeiss D, ocular No. 4.
Blood from numerous other species of fish obtained from a similar source to the above mentioned
was submitted to microscopical examination, but no hæmatozoa were found in any. of the specimens.
The names of the fish were as follows:—
Pattia (Hindi), Barbns stigma.
Mohaylee (Hindi), Labeo diplostomus,
Purri (Punjabi), Notopterus kapirat.
Kugga (Punjabi), Clarias magur.
.Rewah or Rohwa (Hindi), Cirrhnia reba.
Rainy Season Observations.—-Exactly the same ground was gone over at the beginning of September,
and similar investigations to those previously recorded during the hot season tour were made.
Depôt Pond—Cacheri (Trichogaster faciatus, or a variety of this species).—In the blood of eleven
specimens examined, the small variety of the hômatozoon was found present, varying from numerous to
few; and absent from the circulation of seven.
Old Jumna River.—The small variety of hæmatozoon was present in one, and absent from the
blood of two fish examined.
Old Jwmna River.—Grisauli or Girai (Ophiocephalus striatus). No hæmatozoa were found in the
blood of the three specimens examined.
Jumna River.—Singhi (Macrones. seenghala).—The blood of three specimens of this species was
submitted to examination with the result that the large variety of hæmatozoon was found to be nume-
rous in one and absent from two fish.
Specimens of blood were likewise taken from fish of different genera, as was the case during the
investigations conducted during the hot season, but the results proved again to be of a negative
character.
SECTION III
PRECIS OF XPERIMENTAL CASES
Horse No. XLIII—This
animal was subcutaneously inoculated on September 22nd, 1891, over the
right scapular region with blood containing hæmatozoa resembling those found in the blood of Surra
cases, mixed with normal saline solution, taken immediately after death from a specimen of " Raynchob-
della aculeata; Baum (Hindustani) Warm (Mahratta). A raised tumour appeared at the seat of inocu-
lation on the following day, which continued to increase in size until the 24th, and then gradually dis-
appeared. A few petechiæ appeared on the conjunctival membranes on the 20th, together with a muco
purulent discharge from the left nostril. Again well marked ecchymoses were noted on the 23rd Octo-
ber and 11th November, together with a yellow colouration of the visible mucous membranes on the
latter date.
The temperature which registered 35.7° C. at the time of inoculation during the next three weeks
oscillated between 38.7° C. and 35.5° C., but from the 12th October to the 3rd November, presented well
marked evening exacerbations, and morning remissions frequently varying as much as 2° C. between the
two observations. On the 4th November, however, the temperature registered 35.7° C. in the morning
followed by an evening temperature of 37.8° C, and from this time it became gradually elevated until
a maximum of 39.8° C. was attained at midday on the 11th of November. From this time until death,
which occurred on the 23rd November, marked remissions and exacerbations took place several times
varying as much as 3°C. between two registered readings.
Autopsy.—Body somewhat emaciated, tissues tinged an orange colour, few dark-red ecchymoses were
present on the membranæ nictitantes, and there was slight oedema of the hind limbs. Thorax was free
from fluid and pleuritic adhesions. Lungs.—Both apices were the seat of a localized emphysema. The
right also presents a patch of consolidation on the superior surface near the apex which on section was
found to have the lobules divided off from one another by a deposition of jelly-like exudation. The
tissues otherwise presented a healthy appearance. The Pericardial sac contained 1½ oz. of a turbid yellow
