The Atmospheric-Germ Theory


WE have heard much during the last week or two concerning the presence of organic matter in the atmosphere, and the degree to which this is filled with “germs” of living things. It would have been better, perhaps, had it been always pointed out more distinctly that the two expressions were by no means uniformly convertible. There is unquestionably much mere organic débris in the atmosphere which nobody could regard as germs of living things.
