SupphmBut to the "'Tropica? AgrculhinsL^ [Oct. 1, 190-?, 
the traehea or Cesophagiis. Slight catarrhal 
iiifliimrantion is sometimes met with in the 
bronchial tubei5, with collajise of some of the 
smaller lobules. Pulmonary emphyjema mny 
nlso be present, but, as Williams remarks, this 
is due to the formation of gases in the areolae 
of the connecting tissue. But the changes in 
the lungs are neither constant nor pathogno- 
monic, and are secondary na a rule. Tiiere 
is sometimes echymotic patches on the endo- 
cardium of the heart, and similar spots are 
met with, occasionally, on tlie epicardium, with 
a' little fluid in the pericardial sac. On opening 
the abdomen, the peritoneum i^ congested and 
vefy f 'efquently' spotted, and there is a variable 
quantity of a yellow serous fluid in the 
peritoneal cavity. It is comparatively rare to 
find any pathological changes in the first and 
second stomachs, although a little serous infiltra- 
tion is sometimes met with under the epithelial 
lining. 
"The third stomach is generally hard, and 
the food between the leaves dry and caked. 
But very froquently, more especially if the 
sick animal has been allowed to drink large 
quantities of water, tlie contents of the third 
Btomach are found quite fluid. 
" It is in the abomasum or fourth stomach, 
an^ the intostiiiei», wliere the most marked 
ard cliaracteristic changes are met v/ith. The 
mucous membrane of this stomach is the seat 
of acute catarrhal inflammation, the sub-mucous 
tis'sue is swollen, and infiltrated with a serous 
effusion, especially on the rugre or folds. The 
mucous mombrane is also swollen, and its 
epithelium detached -desquamated — in patches 
of vatious sizes, leaving ulcerated sores, more 
particularly near the pyloris or bowel, and, 
where these ulcers present the appearance of 
dark eroded soies, with the yellow degenerated 
tissue resting in their centre?, small petechial 
spots are often found studded all over the 
congested area. 
In the small intestines we find congestion 
and inflammation of varying degrees of intensity, 
vrith a muco-purnlent greyish yellow exudation, 
in some cases covering innumerable small spots 
scattered all over the mucous membrane of the 
bowels; in other cases this exudation is found 
covering almost the whole surface of the mucous 
membrane. In more severe cases this presents 
the appearance of a thick croupous-lookiug 
exudate, which — in parts — forms u complete 
cast of the bowels, 
-"In such cases the epithelium is thickened, 
softened, and is found detached over large 
patches throughout the small intestines, leaving 
the membrane I'ed and granular looking. Peyers, 
glands or patches are generally inflamed, swollen, 
and denuded of epithelium. The changes in 
the large intestines are not usually so well 
marked or so uniform. In many cases the 
inflammation is more in patches, and in the 
rectum the mucous membrane is often intensely 
inflamed, atid presents a blood-streaked appear- 
ance. The epithelium is swollen, and covered 
over with a niuco-purulent exudate, while there 
18 more or less infiltration of the sub-mucous 
tissue, lu toany severe cases, however, the 
large intestines are ju^t as seriously affected 
as the small, with numerous small patches of 
desquamated epithelium. It is a very curious 
fact also that many of the cases which majiifest 
the most severe external sj'mptoms do not show 
the most characteristic post-mortem lesions. 
"The liver very often appears congested, and 
presents a yellowish colour of varying tints. 
In many of the cases, however, the liver is 
perfectly normal in character and appearance, 
and the gall perfectly healthy. The raucous 
lining of the gall-bladder is sometimes iiiflimed, 
especially about the bise of the sac, and 
studded all over with blood spots. The gall 
presents varying shades of colour, from a deep 
green to almost blood red, and is often thick 
and curdy looking. The muc )u-? lining of the 
urinary bladder is sometimes affected also in 
patches with a little sub-mucous infiltration, 
and similar appearances present themselves in 
the vagina of the female. It is not my intention 
to go minutely into all tlie post-mortem changes 
which maj- be observed in individual cases. 
The most marked asid pathognomonic 2^'^'it-morlem 
appearances aie those seen in the mouth and 
upper air passuges, and in the fourth stomach 
and intestines. 
"The medicinal treatment of Rinderpest 'is 
seldom followed by any satisfactory results. 
A large number of medicinal remedies were 
tried, such as germicides, anodynes, astringents 
and laxatives, alone and in various combinations. 
Some of these appeared to exercise a beneficial 
effect, but I am strongly of opinion that the 
varying success which attended the administration 
of these several remedies depended more upon the 
mild or severe nature of the particular outbreak-:, 
than upon any specific action exercise! by the 
medicine. In its usuil virulent form, ten j)er 
cent, of recoveries was considered a very fair 
average, but in some outbreaks fifteen, twenty 
and up to thirty per cent, of recoveries were 
recorded, more particularly daring the hot dry 
summer weather. 
" In India they iiave had the same experience. 
Pease says : — ' The disease in some parts of India, 
and notably those parts which are naturally hot 
and arid, where the temperature of tlie air rises 
very high, is frequently noticed to be of a far 
milder type than is the case more particularly in 
the hills, and it has appeared probable that 
desiccation of the virus by the great heat and 
dryness influences its virulence to a considerable 
extent — 60 to 65 per cent, of recoveries may 
sometimes be observed in the hot districts of the 
plain.' 
"t think there can be little doubt that dry heat 
does exercise a modifying influence on the viru- 
lence of the disea-^e, but it does not altogether 
account for the exceptionally mild form that the 
di-ease assumes on individual farms here and 
there in a district' where the climatic and other 
conditiosis are similar to those on other farms 
adjoining, where the disease presents its usual 
virulent character." 
Be that as it maj', I am of opinion that if care- 
ful statistics could be collected, it would be shown- 
that, where the affected cattle could be properly
