Tho common cold be It one disease or several sev-eral Is pow regarded as an Infection, and colds from Infected persons are surely known, hut there are still le-llnis le-llnis who trace their troubles to wet feet, or sitting In a draft. An Inference Infer-ence has been that the disease bacteria inny rest Inert on the mucous membrane mem-brane of the throat until stirred to action ac-tion by the chilling of the body. A familiar explanation Is that chlllfng of the sk'lu drives the blood to the Internal In-ternal organs, and by congestion less-ens less-ens their reslstnnce, but the late St. Louis experiments of S. Mudd nnd S. II. (Irant hnve shown that there Is no such congestion. The temperature of the skin and mucous membranes actually actu-ally falls with chilling of distant parts of the hotly surface and rises again when the person Is warmed externally. The Investlgntnrs conclude that Interruption Inter-ruption of the circulation may brim; Infection by upsetting the equilibrium between host and micro-organisms In such a way ns decreasing the resplni-I resplni-I tlon of the cells, retarding waste re-' re-' uinvnl, or lessening the local supply of the antibodies of Immunity. |
