opinion that the infection was brought into Xi-Be by some strange Indian 
who had crossed the Rio Hondo from the Yucatan side. 
Corosal is surrounded by swamp, and there are numerous pools and street 
drains overgrown with weeds which afford a very favourable ground for the 
breeding of the Anopheles. I found Anopheles larvae, the species of which 
I was unable to determine, in the street puddles, and Malaria is the prevalent 
disease. (See Medical Reports of Corosal, Chapter VI.) 
The water supply of the town consists of some large water vats, and 
numerous odd receptacles and wells. I found larvae abundant in all of those 
which I examined, and I was able to identify the Stegomyia fasciata in 
several yards. With the exception of the houses placed immediately on the 
sea front, and which have the advantage of a very refreshing breeze, the 
lots like those at Belize harbour the Stegomyia in large numbers, and if 
therefore a case of Yellow fever were introduced, the suitable mosquitoes are 
at hand to propagate the disease. 
• There has been no attempt at screening the cisterns, and there appeared 
to me to be many more barrels in proportion to regular cisterns than at 
Belize. In view of the fact that the inhabitants who for the most part are 
annual tenants have little interest in erecting suitable water reservoirs, the 
remedy of providing a properly screened water supply rests with the 
property owners of Corosal. A properly protected water supply system is 
undoubtedly needed, for in its present state Corosal is a very vulnerable spot 
in the Colony. 
It is considered that it would be an easy matter to patrol the front of 
Corosal, and so prevent the introduction without quarantine of persons coming 
from infected districts, and it is also stated that the three “ roads ” which 
enter from the back of the town could be guarded in times of danger. I am 
of opinion, however, that if Yellow fever should break out on the Mexican 
side close to the British frontier the greatest difficulty would be encountered 
in preventing its introduction. 
Not only should the water supply be remedied, but as Corosal is a port 
of entry into the Colony for shipping, liable to come from infected parts, 
there should be in addition a properly screened quarantine station. There is, 
it is true, a small general hospital, but it is of even greater importance to 
the prosperity of the Colony that there should be a small properly screened 
infectious diseases isolation hospital for the reception of real or suspicious 
cases. The Medical Officer in charge of Corosal ought to be furnished weekly 
with the health returns of other parts of the Colony, of Mexico and of 
adjacent Rebublics. In return the Medical Officer should furnish the Senior 
Colonial Surgeon at Belize with a weekly report of the health of the district. 
There should be far more com?nunication between the medical head of the 
Colony at Belize and the Medical Officers at the extreme ports of the Colony , 
Corosal and Punta Gorda than exists at present.
