If it does so, no thickness is of any avail in keeping out the cold ; hence the advantage of skin caresses, buffalo robes, leather sheets, and macintosh rugs. All cloths lose much of their closeness of texture in a hot, dry climate; the fibres shrink extremely, and the wind blows through the tissue as through network.
