We have to acknowledge a second edition of Where to

Find Ferns, with a Special Chapter on Ferns Round London, By Francis George Heath. (Sampson Low and Co.)—Mr. Heath gives the particular positions, but not the exact spots, in which ferns grow. Hence the reader will have to exercise his intelligence in applying principles, and the mere collector, who extirpates wherever he goes, will be baffled. It is to be hoped that every intelligent botanist will tako care that no habitat of a rare fern shall cease to be so for anything that he may do.
