mes to ask a question or two. For example, it is commonly thought that
children must have what are commonly called "children's epidemics,"
"current contagions," &c., in other words, that they are born to have
measles, hooping-cough, perhaps even scarlet fever, just as they are
born to cut their teeth, if they live.

Now, do tell us, why must a child have measles?

Oh because, you say, we cannot keep it from infection--other children
have measles--and it must take them--and it is safer that it should.

But why must other children have measles? And if they have, why must
yours have them too?

If you believed in and observed the laws for preserving the health of
houses which inculcate cleanliness, ventilation, white-washing, and
other means, and which, by the way, _are laws_, as implicitly as you
believe in the popular opinion, for it is nothing more than an opinion,
that your child must have children's epidemics, don't you think that
upon the whole your child would be more likely to escape altogether?

[Sidenote: Health of carriages.]

The health of carriages, especially close carriages, is not of
sufficient universal importance to mention here, otherwise than
cursorily. Children, who are always the most delicate test of sanitary
conditions, generally cannot enter a close carriage without being sick--
and very lucky for them that it is so. A close carriage, with the
horse-hair cushions and linings always saturated with organic matter, if
to this be added the windows up, is one of the most unhealthy of human
receptacles. The idea of taking an _airing_ in it is something
preposterous. Dr. Angus Smith has shown that a crowded railway carriage,
which goes at the rate of 30 miles an hour, is as unwholesome as the
strong smell of a sewer, or as a back yard in one of the most unhealthy
courts off one of the most unhealthy streets in Manchester.

God lays down certain physical laws. Upon His carrying out such laws
depends our responsibility (that much abused word), for how could we
have any responsibility for actions, the results of which we could not
foresee--which would be the case if the carrying out of His laws were
not certain. Yet we seem to be continually expecting that He will work a
miracle--i.e., break His own laws expressly to relieve us of
responsibility.

I must say a word about servants' bed-rooms. From the way they are
built, but oftener from the
