can give off effluvia or moisture. Out of all damp towels, &c., which
become dry in the room, the damp, of course, goes into the patient's
air. Yet this "of course" seems as little thought of, as if it were an
obsolete fiction. How very seldom you see a nurse who acknowledges by
her practice that nothing at all ought to be aired in the patient's
room, that nothing at all ought to be cooked at the patient's fire!
Indeed the arrangements often make this rule impossible to observe.

If the nurse be a very careful one, she will, when the patient leaves
his bed, but not his room, open the sheets wide, and throw the bed
clothes back, in order to air his bed. And she will spread the wet
towels or flannels carefully out upon a horse, in order to dry them. Now
either these bed-clothes and towels are not dried and aired, or they dry
and air themselves into the patient's air. And whether the damp and
effluvia do him most harm in his air or in his bed, I leave to you to
determine, for I cannot.

[Sidenote: Effluvia from excreta.]

Even in health people cannot repeatedly breathe air in which they live
with impunity, on account of its becoming charged with unwholesome
matter from the lungs and skin. In disease where everything given off
from the body is highly noxious and dangerous, not only must there be
plenty of ventilation to carry off the effluvia, but everything which
the patient passes must be instantly removed away, as being more noxious
than even the emanations from the sick.

Of the fatal effects of the effluvia from the excreta it would seem
unnecessary to speak, were they not so constantly neglected. Concealing
the utensils behind the vallance to the bed seems all the precaution
