There is really very little danger of contracting tuberculosis in public conveyances although some people have a great fear of getting the disease in this way. Here again, as in the hotel, the time during which both the consumptive and the well person occupy the conveyance is too short to implant the disease. The sleeping berths on railroads over which a great many consumptives travel may become dangerous to people who are greatly predisposed to the disease but even here the danger is not great.
