One case of Relapsing Fever was observed by Dr. Fletcher. Spirilla 
Obermeieri were found in large numbers. The patient was from Northern 
India and had only been a few days in the country so that he brought 
the disease with him. He had a single attack and no relapse. The disease 
has not spread. 
In frogs of several species and in a crocodile Drepanidia were found 
1 hose in the crocodile were peculiar on account of the extensive vacuolation 
No extra corpuscular forms were observed. They displaced the nucleus of 
the red corpuscles in a manner similar to that of one species found in frogs, 
but otherwise have no close resemblance to those parasites. 
Coocidium Oviforme is found in the majority of rabbits either imported 
or bred in the country. 
Sarcosporidia in large numbers were found in the cardiac muscle of an 
imported Australian bull which died some three months after arrival in the 
country. At first the animal appeared to be in good health but then 
commenced to get “ lever.” Texas fever was suspected, but though numerous 
examinations were made the pirosoma was never found. Irregular though 
less severe fever continued for nearly up to the time of death, and the animal 
steadily lost weight and condition. The immediate cause of death was 
mtercurrent disease Acute Pleuropneumonia and Pericarditis. 
Helminths. 
The number of intestinal and other worms met with in lower animals in 
the Malay Peninsula was very large. As none of these seem to attack man 
or the domesticated animals, only those found in man and domesticated 
animals are, with a few exceptions, here considered. 
. ;^- s regards the presence of these parasites in man it must be borne in 
mind that they are not necessarily indigenous, as the greater number of the 
examinations were made on Chinese or other imported races of mankind, 
and that the greater number of domesticated animals are also imported. As,

diffused, the importance of their occurrence is or may be great. 
PIatyhelminths. — In man the Trematodes are represented by Distoma 
Sinense, Opisthovcis Sinensis , which has been found on several occasions, five 
out of 328, in the gall bladder or bile ducts of Chinese residents. Though 
the bile ducts are often much distended these parasites do not cause 
symptoms of obstruction or apparently produce any serious disease. Ova 
of these worms have been sent from other parts of the States so that it 
appears to be widely diffused amongst the Chinese now resident here. In 
the lower animals Trematodes are more common. 
Mr. Ford, Government Veterinary Surgeon, has observed in Bullocks 
and Buffaloes Amphistoma conicum at almost every examination of the rumen 
of these animals. In one bullock unusually large, 35 mm., specimens of the 
Distoma Hepaticmn readily recognised by the cuticular prickles were found in 
the li\ er. P rom another bullock he forwarded to me a specimen of the 
spleen with the venous cavities dilated with innumerable specimens of 
Bilharzia Cvassum (ichistostoma Crassum). There is no reason to believe 
that this parasite is common. The human species of the Schistostoma 
appears to be unknown here. No other organs were forwarded for examina¬ 
tion, but as the spleen is an uncommon place for the accumulation of this
