The sunny side of the street should always be chosen as a residence,
for its superior healthfulness. In some barracks in Russia, it was
found that in a wing where no sun penetrated, there occurred three
cases of sickness for every single case which occurred on that side of
the building exposed to the sun's rays. All other circumstances were
equal--such as ventilation, size of apartments, &c., so that no other
cause for this disproportion seemed to exist. In the Italian cities,
this practical hint is well known. Malaria seldom attacks the set of
apartments or houses which are freely open to the sun; while, on the
opposite side of the street, the summer and autumn are very
unhealthful, and even dangerous.
