Found this while preparing for a lecture class on cholera. Wish we had
a way of handling statistical data like John Snow where the data was
more visible. Rakesh

What is important about John Snow is his recognition of the power of
statistics. He didn't know what the organism was that caused Cholera,
so instead he gathered what might have been thought of as 'anecdotal'
evidence - stories. But the cumulative effect of his meticulously
gathered data was devastating - and was the beginning of the end for
Cholera in Britain.
