It will be unnecessary to explain the need for the work above indicated to any one who has attempted the culture, particularly the identification of the ringworm fungi. For the sake of others, let it be said, first, that the proposition is very different from the cultivation of the bacteria, and that the difficulties are not along microscopic lines, but preeminently from the gross morphologic standpoint. Yet more precisely, we are not concerned so much with the matter of luxuriance of growth, for at present our fungi grow easily enough. Rather are we trying to coax out differential characteristics. It is with the latter phase that this paper has to deal; but before proceeding to our experimental work some preliminary considerations must be offered to make the work understandable.
The problems before us can best be comprehended by keeping in mind throughout that the molds are plants. Much higher than
