* The Ferns are naturally poorly represented in Middlesex, and in consequence of 

 being marketable, have become of late years very scarce in the vicinity of London ; some 

 have been quite eradicated. We quote the nature-printed plates in the octavo edition of 

 Mr. Tliomas Moore's British Ferns, where are figures and descriptions of very many 

 'varieties.'
