though symptomatically very closely allied to Rinderpest, is
not affected by the methods at present strongly advocated for
the prevention of Rinderpest.
4. Since the date of the preliminary report
four outbreaks of this disease have occurred (3 on Hongkong
Island and 1 on Lantao) the outbreak being so virulent in one
case as to necessitate the slaughter of the whole herd of 55
animals. Owing, however, to one animal having been found suffering from Trypanosomiasis and to an outbreak of another
disease which appears to have yielded to large doses of quinine and is referred to by the investigators as Pyroplasmosis
or so-called Texan Fever, the investigators have come to the
conclusion that Trypanosomiasis and Pyroplasmosis, "diseases
of signal importance in regard to successful cattle breeding"
should be investigated thoroughly previous to undertaking prophylactic and curative measures against Haemorrhagic Septicaemia,
the disease now entailing losses on the Colony.
5. I am not quite clear as to the soundness
of this policy but the subject is so technical that it is
doubtless best to leave entirely to the technical Officers
the determination of the course of investigation which will
the soonest lead to the meat and milk supply of the Colony
being secured from interruption and being derived in the
future more than it is at present from within the boundaries
of the Colony itself.
