tightly.

It is very important that the clothing should be kept clean. That which
is worn for a long time becomes saturated with the excretions and
exhalations of the body, which prevent free transpiration from the pores
of the skin, and thereby induce mental inactivity and depression of the
physical powers. Unclear clothing may be the means of conveying disease.
Scarlet fever has been conveyed frequently by the clothing of a nurse
into a healthy family. All of the contagious diseases have been
communicated by clothing contaminated in laundries.

Certain dyes which are largely used in the coloring of wearing apparel
are poisonous, and give rise to local disease of the skin, accompanied
in some instances, with constitutional symptoms. The principal poisonous
dyes are the red and yellow aniline. A case of poisoning from wearing
stockings colored with aniline dyes, in which there were severe
constitutional symptoms, came under our observation at the Invalids'
Hotel recently.
