Now, if a clothing possesses no porosity, e. g., the mackintosh, and rubber clothing generally, even without exercise, there would collect somewhere beneath it a quart of water, but if exercise be indulged in, the quantity may become large indeed; particularly after the atmosphere beneath has been surcharged with vapor, and evaporation ceases to occur from the surface, and with it the grateful c
