way they are kept, and from no intelligent
inspection whatever being exercised over them, they are almost
invariably dens of foul air, and the "servants' health" suffers in an
"unaccountable" (?) way, even in the country. For I am by no means
speaking only of London houses, where too often servants are put to live
under the ground and over the roof. But in a country "_mansion_," which
was really a "mansion," (not after the fashion of advertisements,) I
have known three maids who slept in the same room ill of scarlet fever.
"How catching it is," was of course the remark. One look at the room,
one smell of the room, was quite enough. It was no longer
"unaccountable." The room was not a small one; it was up stairs, and it
had two large windows--but nearly every one of the neglects enumerated
above was there.

and dogs, but conditions growing out of one another.]

Is it not living in a continual mistake to look upon diseases, as we do
now, as separate entities, which _must_ exist, like cats and dogs?
instead of looking upon them as conditions, like a dirty and a clean
condition, and just as much under our own control; or rather as the
reactions of kindly nature, against the conditions in which we have
placed ourselves.

I was brought up, both by scientific men and ignorant women, distinctly
to believe that small-pox, for instance, was a thing of which there was
once a first specimen in the world, which went on propagating itself, in
a perpetual chain of descent, just as much as that there was a first
dog, (or a first pair of dogs,) and that small-pox would not begin
itself any more than a new dog would begin without there having been a
parent dog.

Since then I have seen with my eyes and smelt with my nose small-pox
growing up in first specimens, either in close rooms, or in overcrowded
wards, where it could not by any possibility have been "caught," but
must have begun. Nay, more, I have seen diseases begin, grow up, and
pass into one another. Now, dogs do not pass into cats.

I have seen, for instance, with a little overcrowding, continued fever
grow up; and with a little more, typhoid fever; and with a little more,
typhus, and all in the same ward or hut.

Would it not be far better, truer, and more practical, if we looked upon
disease in this light?
