A fabric, therefore, so constructed as to allow a layer of woolen
fibre to lie between the skin and a layer of cotton fibre, and
sufficiently open and loose as to contain the largest possible
amount of air is the ideal. _The Jaros Hygienic Underwear material,
a new fabric, seems beautifully adapted to this end. A layer of
woolen fibres, soft and fleecy, is firmly held on one side of and
in the meshes of an exceeding porous cotton fabric, so that while
one extremity of a fibre lies against the skin, the other is in
contact with the cotton; thus admitting of the rapid transference
of all dampness of perspiration to the cotton where it is retained,
and consequently leaving no moisture next to the skin to absorb and
diminish the heat of the body. The importance of this subject, and
the possibilities of this new fabric for the prevention of colds, and
their resultant diseases, can only be appreciated when we remember the
simple fact that it is impossible to take a cold so long as a healthy
condition of the skin, and an even temperature of the surface of the
body, are maintained_.
