It is wonderful how an error once started, becomes prevalent, even among those who should know better. As the word " a fungoid disease " fell from the lips of the Editor some years ago, Prof. C. V. Riley, who was at his elbow remarked "why do you say fungoid disease ?"

There has been no need for Prof. Riley or any other person to ask that question of the Editor since. But we see it in works in the old world, of the highest scientific pretensions; "a fungoid disease" means a disease resembling a fungus. It is the intention to say a disease originating through the operations of a fungus; we mean a fungal, not a fungoid disease. Many a time have we mentally thanked Professor Riley for the hint.
