It is in this manner shown that after the lapse of more than 
half an hour, the cholera germs may still adhere to living insects. 
And if we bear in mind what long distances flies may accomplish 
in such a time, the possibilities of having eatables infected, such 
as soup, pudding, milk, etc., must not be undervalued. 
In conclusion I wish to remind you of a somewhat heroic deed 
which an Australian community performed a few years ago. The 
steamer ‘‘ Dorunda” had arrived with cholera patients on board 
at Townsville and was ordered to proceed south. But the Towns- 
ville people, most anxious to give help and to separate the healthy 
from the affected, petitioned the Queensland Government to allow 
the passengers to land at their Quarantine Station, inviting as it 
were, the disease into their midst, well knowing what dangerous 
possibilities to their own welfare this action might involve. I 
have always considered this spirit of the Townsville people as a 
true ‘spirit of courage and philanthropy. What a gontrast is not 
this to the action of an American crowd on a similar occasion, 
who prevented forcibly the landing of females and children—in 
a healthy state, but exhausted through exposure—at the Quaran- 
tine Station near New York in September last.
