een as much filth as in 1883. It
has never become endemic there, as it is a rainless country and generally
too dry for the cholera germ to thrive.
Marseilles had a small outbreak of cholera in the fall of 1883, probably
derived from Egypt, which she carefully concealed. In addition, cholera
was also brought to Toulon from Tonquin by the Sarthe and other vessels.
Toulon concealed her cholera for at least seventeen days, and did not
confess it until it had got such headway that it could no longer be
concealed. At least twenty thousand Italians fled from Toulon and
Marseilles, and others were brought away in transports by the Italian
government. Rome refused to receive any fugitives; Genoa and Naples
welcomed them. There were at least three large importations into Naples.
The outbreak in Genoa was connected with washing soiled cholera clothes
in one of the principal water supplies of the city, and Naples has many
privy pits and surface wells. These privies, or _pozzis_, in the poorer
parts of many Italian towns, are in the yards or cellars, and are so
arranged that when they overflow, the surplusage is carried through
drains or gutters into the streets.
In the lowest parts of Toulon there were no privies at all, and the
people emptied their chamberpots into the streets every morning. This
flowed down toward the harbor, which is almost tideless. Toulon always
has much typhoid fever from this cause; but no cholera unless it is
imported.
The great outbreaks of cholera in Paris in 1832, 1848, 1854, and 1865
have been explained at last by Dr. Marcy. The canal de l'Ourcq is one of
the principal water sources of Paris. The market boats or vessels upon it
and at La Villette are so numerous that Marseilles and Havre alone
outrank it in shipping. The parts of Paris which are always most severely
attacked with cholera, and where the most typhoid fever prevails, are
supplied with this water, into which not only all the filth of the boats
goes, but many sewers empty.
I agree with all that is generally said about civic filth favoring the
spread of cholera, but it does not generate, but only supplies the
pabulum for the germs. I believe as long as the Croton water is kept pure
there can be no general outbreak of cholera in New York, only isolated
cases, or at most a few in each house, and those only into which
diarrhoeal cases come, or soiled clothes are brought; that it will not
spread even to the next house, and that there are
