Moreover certain animals, rabbits and guinea pigs, are highly suscep¬ 
tible to Haemorrhagic Septicaemia and immune to Rinderpest. The blood 
and scrapings from the glands of cattle with the disease were injected either 
subcutaneously or intraperitoneally into 12 rabbits and 14 guinea pigs, and 
in no case were these animals infected. 
In cases where the cattle or buffaloes had been dead for some hours the 
results of injection were uncertain and some of the injected animals died, but 
even in these cases the organisms found in the tissues and fluids of the dead 
rabbits or guinea pigs were not those of Hemorrhagic Septicemia , and the 
organisms obtained in such cases from the blood or serum of the cattle 
varied in different cases and could usually be identified as organisms 
commonly met with in the early stages of putrefaction. The organisms 
recovered from the blood or tissues of the animals in no case were those of 
Hemorrhagic Septicemia. 
The outbreaks at Port Swettenham and Kwala Lumpur were the ones 
investigated bacteriologicallv, and the negative evidence against the disease 
being Hemorrhagic Septicemia was conclusive. 
At Dusan Tua the buffaloes had been dead for some hours, and though 
the injection of blood was fatal to the smaller rodents and organisms were 
obtained by culture from the blood of these animals the organisms isolated 
either from the direct cultures or after passing through the small rodents 
were not those of Hemorrhagic Septicemia. 
All attempts at finding any organism, animal or vegetable, bacterial or 
protozoal, to which the causation of the disease could be assigned have 
failed. The frequent presence of Pirosoma in cattle and in one buffalo only 
of a trypansome were merely examples of concurrent diseases. 
The course of the outbreaks and the manner in which the disease 
spreads is of great practical importance, as on the knowledge of such factors 
measures for the prevention must be based. 
It may be stated at the outset that though there is evidence that wild 
pig and some domesticated pigs get the disease and that it is probable that 
other game, particularly the Sladang, may do so. No part seems to have been 
played by these animals in the spread of the Selangor outbreaks. No 
spread could be traced to goats and no cases occurred amongst the goats, 
nor was I successful in artificially by inoculation transmitting the disease to 
goats. I am aware that in some outbreaks of Rinderpest some breeds of 
goats have been proved to be susceptible. 
For all practical purposes in Selangor the disease can be considered as 
one transmitted from Cattle or Buffaloes to Buffaloes or Cattle directly or 
through the medium of fairly fresh discharges from diseased animals. 
The disease is not endemic and districts may remain for years free from 
the disease. When imported, however, it rapidly spreads unless active 
measures are taken to prevent the spread of infection. Though not endemic 
it is rare to find all parts of the Malay Peninsula free from the disease at any 
one time, and cattle are also imported from India, Siam, and the Malay 
Archipelago, and kept for a variable period at Singapore or Penang. I hrough 
these Cattle the disease is, from time to time, re-introduced. In Selangor in 
the period under review there were five definite importations of the disease. 
Two of these were detected and stopped at Port Swettenham, viz., one 
amongst Malay buffaloes in November, 1903, and one amongst Indian 
buffalo calves in June, 1904. Two other importations were unfortunately 
not detected at Port Swettenham but were seen amongst the recently
