l/6th objective and No. 4 ocular. A special feature of these spindle-shaped, non-
motile bodies, then noted, was that they were found in groups or clumps. There
was a considerable amount of blood in the faeces which was negative for Amoebae
or their cysts, but some rounded bodies, which represent a stage in the develop-
ment of the parasite under report, were found and were at that time considered as
vegetable spores, which they resemble. The faecal films were not stained, so the
morphology and histology of the elements of the parasite present in the faeces
could not be thoroughly studied.

With regard to the particulars and place of origin of the affected oxen, it is
interesting to note that all of these animals, which were about eight years old,
belonged to various bullock corps raised in the 8th Lucknow Division, Supply
and Transport Corps and, as far as the writer could ascertain, they were purchased
from Etawah District of the United Provinces. These oxen were either of local
or mixed United Provinces and Hariana breeds. All the four cases had suffered
several times from dysentery and were consequently in poor condition. They
were considered to be affected with rinderpest and were destroyed.

                                      POST-MORTEM FINDINGS.

Case No. 1.—Nothing unusual was found on examination of the skin, nor
did the examination of the buccal, pharyngeal and laryngeal mucous membranes
reveal anything except rinderpest vesicles and ulcers. In the abomasum in the
area of the pyloric glands, whitish spherical spots were seen which, on minute exa-
mination with a hand lens, appeared to be parasitic cysts about the size and shape
of small tapioca grains. The largest of these looked somewhat smaller than an
individual sarcosporidium and was about 1 mm. long.

One or two of these cysts were found at the beginning of the duodenum and a
few at the end of the ileum. Nothing special was noticed in the rest of the bowel
except rinderpest lesions. The cysts were not found in the heart, skeletal
musculature, oesophagus or diaphragm, which were especially examined for Sar-
cosporidia.

Case No. 2.—The findings of this case were identical with the first one,
except that a few petechiae and patches of congestion were seen in the area where
these cysts were present near the ileo-caecal valve. Only a few were noticed at the
pylorus and the caecum was not involved.

Case No. 3.—Showed a heavy infection throughout the ileum but only a few
at the pylorus.

Case No. 4.—In this case there was only one visible focus of infection, but
this was peculiar in that the cysts were arranged in a semi-circular fashion
around the ileo-caecal valve about half an inch towards the ileum. There was a
zone of intense congestion, which was attributed to rinderpest. This animal
