But the heat is not the only cause, nor even the most
important cause, of summer diarrhoea, though it
doubtless is a factor. That this is the case can be very
readily seen by comparing the niunber of deaths from
acute diarrhoeal diseases in New York State in the
two years, 1900-1901, in the period from May 1
to November 1, inclusive. The summer of 1901
was exceptionally hot, but the deaths from diarrhoeal
diseases in the state, outside of Greater New York
City, numbered little more than half of the deaths
recorded during the same period, in the same area,
in 1900, when the heat was much less intense. On the
other hand, the nimiber of deaths in Greater New York
and suburbs from the same diseases was very nearly
doubled. The figures were : —
