Yaws occur amongst the Sakies (aboriginal inhabitants) of Malaya in 
some of the remote districts. Vide Report by Dr. Gimlette “Notes on 
;ome Methods of Employed by Kelantan Malays in the Treatment or Euru 
)i* Yaws n 
Yaws locally known as “ Puru ” is also a common disease amongst the 
Malays on the Pahang River. In every village visited cases were seen m 
iome of the children. Children in arms and up to about io or 12 were 
iffected. No cases were seen in adults. Many of the other children had 
scars from this disease indicating comparatively recent attacks. A 
considerable proportion of the children are not attacked, and in this the 
condition differs from that in Fiji where the disease is universal amongst 
the children. The scarcity of flies and the smaller houses are probably 
sufficient to explain the difference. Various forms are distinguished by the 
natives as in Fiji and in the West Indies. These distinctions are based on 
the arrangement and amount of the eruption on the parts mainly affected. 
The eruption itself is characteristic and indistinguishable in appearance and 
in course from the Yaws of the West Indies, West Africa and Central Africa 
and the “ Coko ” of the Fijians. A primary sore usually on the feet legs or 
hands is recognised in most cases. These are the places most exposed to 
injury and it is probable that infection takes place in the great mass of 
cases through some breach of the cuticle. 
So much has been written on the relationship between Yaws and 
Svphilis and the statement that Yaws is merely a racial or climatic modifi¬ 
cation of Syphilis that it may not be out of place here to state that I have 
now seen Yaws in different races of Negroes, Chinese, Natives of various 
parts of India, Portuguese, English, Polynesians, Melanesians and Malays, 
and in the offspring of various combinations of several of these races. 
I have also seen the disease in such different climates as those of Fiji, 
British Guiana, Central Africa, W est Africa and Malaya. In all these 
climates and amongst most of these races Syphilis also occurs and the 
two diseases are easily distinguishable from each other and “ oreed true. 
The disease in Malaya is probably indigenous. 
In the lower animals granulomata appear to be 'uncommon. I he 
granuloma affecting the genitalia of dogs, common in many tropical 
countries, has not been seen here. . . , 
Glanders has been recorded but no case occurred during the period 
under review. , . . . , • 
An imported horse which had been many months m the colony and in 
apparently good health gradually began to lose condition, a chronic 
irregular fever set in with exacerbations of more severe fever and later 
subcutaneous swellings appeared. At first these were only on the hind 
leo-s but later on the fore legs also, the abdomen and the neck. I hese 
swellings varied in size, they were not hot and were moderate y so t. 
When advanced distinct fluctuation was obtained. The swellings, whether 
allowed to burst naturally or opened, discharged glairy yellow fluid or thick 
pus. The ulcers formed healed fairly readily in some instances and in 
others slowly or incompletely breaking down again. , 
More of these swellings continued to form as the old ones healed, and 
later yellow thick fluid streaked and stained with blood was discharged 
from time to time from the nares. 
Blood examination was negative except on the occasion ^hen 
Mr. Ford found an embryo filaria. The result of injections of blood
