inoculated with rinderpest blood and suffered from an attack of the disease,
showing that he was susceptible to it, and that the skin used no longer con¬
tained the virus.
Experiment No. XIII.—A bull, aged 4 years, was inoculated subcu-
taneously with 5 c.c. of a saline extract of small pieces of the skin of an animal
which had died of rinderpest, which had been treated with salt in the shade
for two days, and then hung up in a room for 11 days more. The maximum
and minimum temperatures in the shade were the same as in experiments
Nos. XI and XII.
Result.—The temperature, pulse and respiratory curves remained normal
for ten days and no symptoms appeared. The animal was subsequently
inoculated with virulent blood and protective serum according to the simulta-
neous method, but the dose of serum being a large one, and sufficient to prevent
the disease appearing, no symptoms ensued.*
Experiment No. XVI.—In the manger of a bull, aged 4 years, was
placed a piece of the skin of an animal that had died of rinderpest, and which
had been treated with common salt and dried in the shade for two days, and
kept for eight days more hung up in a room. The animal was observed to
lick the skin and was obliged to rub his nose against it in eating ; it was left
in the manger or feeding trough for eight days. The maximum tempera-
ture in the shade during the time this skin was being dried varied between
70° and 75° F., and the minimum between 50° and 54° F.
Result.—The temperature rose on the fourth day, but this was found
to be due to an attack of congestion of the lungs, and soon subsided, no
symptoms of rinderpest appearing during ten days. Owing to the lung inflama¬
tion the susceptibility of this animal to rinderpest has not yet been tested.*
Experiment No. XVII.—A piece of the skin of an animal which had
died of rinderpest, and which had been dried in the shade for two days, and
kept eight days more, the temperature conditions having been the same as in
the two preceding experiments, was placed in the manger of a bull, aged
3 years, and left there for eight days. He was observed to lick it, and could
not feed without his nose and mouth coming into contact with it.
Result.—The temperature, pulse and respiratory curves remained normal
for ten days, and he was subsequently inoculated with virulent rinderpest
blood, and developed a typical attack of the disease.
Experiment No. XVIII.—A piece of the skin of an animal which had
died of rinderpest, and which had been treated with lime in the shade for two
days and kept for eight days more, was placed in the feeding trough of a
bull, and he was observed to lick it and must have come into contact with it
when feeding. The temperatures during the period the skin was being dried
were the same as in experiment No. XII, and it was left for eight days.
Result.—The temperature, pulse and respiratory curves remained normal
for ten days and no symptoms of rinderpest appeared. The animal was sub-
sequently inoculated with virulent blood and developed an attack of the disease,
showing that he was susceptible to the affection, and that the skin used had
lost all power of communicating the disease.
Experiment No. XIX.—A piece of a skin of an animal which had died
of rinderpest, and which had been dried in the sun for three days, one of which
was cloudy, and kept one day more. During the days it was in the sun the
maximum temperature in the shade was 69°, and the minimum 47° F., while
the maximum registered by the solar radiation thermometer on each day was
141° and 142°.
Result.—The temperature, pulse and respiratory curves remained normal
for ten days, and no symptoms of rinderpest followed. The animal was sub-
sequently inoculated with virulent rinderpest blood and developed a typical
attack of the disease.
The above series of experiments prove that the skins of animals which
have died of rinderpest, and which have been either dried in the sun or shade,
or treated with salt or lime in the shade for two or three days, and then kept
hung up in a room for a further period of from four to twelve days in the
different experiments, no longer contain any infection even when submitted
to the extreme test of extracts of them being injected under the skin of sus-
ceptible animals. Further skins treated in the same way, which were put in
* NOTE.—These two animals have been given rinderpest since the above was written, proving they were
susceptible to the disease.
