Abstract
SOME time ago it was reported that colonies of the diphtheria bacterium do not thrive well when exposed to light, and it occurred to me that the electric light might afford a means of checking the development of the false membranes by projecting a very powerful are light on the throat, for it is known that the tissues are to some extent penetrated by light. Or possibly the are light could be sent into the throat through the mouth? I know that in Germany microscopic objects have been lighted with the aid of a lamp placed at some distance, and connected to the microscope by a curved glass rod, which conveyed the light by internal reflection. Incandescent lamps might be used in a similar manner, and some means could be devised in order to intercept the heat they produce, if it be objectionable.
