MARINE 



The earliest contributor to a knowledge of the Marine Algas of Corn- 

 wall was probably Mr. J. Stackhouse of Pendarves, who, at the end of the 

 seventeenth century published a work on Marine Alga? entitled Nereis 

 Britannica, containing numerous illustrations. It is stated in the Biblio- 

 theca Cornubiensis that Mr. Stackhouse built Acton Castle for the purpose 

 of pursuing his researches on Marine Algae, and he was probably the 

 first to experiment on the propagation of alga? from their spores. In 

 the early part of the last century Miss Warren of Flushing paid much 

 attention to this group of plants, and sent many specimens to the late 

 Professor Harvey of Dublin, whose Phycologica Britannica still remains 

 the classical work on British Marine Algae. Desirous of recognizing 

 the valuable assistance he received from her he honoured her name by 

 giving it to a species which he believed to be new, viz. Schizosiphon 

 Warreniae, but which, unfortunately, owing to the recently accepted laws 

 of priority of nomenclature, has been altered to Rivularia Biasolettiana, 

 Menegh., a name previously given to it by an Italian botanist. Dr. 

 Herman Becker, F.L.S., also studied the marine flora of Cornwall and 

 added to it the very rare Desmarestia Dresnayi, Lamour, which he dredged 

 off the Lizard in December 1864. In more recent years Dr. W. P. 

 Cocks, late of Plymouth and Falmouth, and the Rev. W. S. Hore 

 explored that portion of Cornwall between Mount Edgcumbe and Saltash. 

 Mr. Henry Goode worked the same district and also the neighbourhood 

 of Penzance in west Cornwall, where he was fortunate enough to meet 

 with the rare Carpomitra Cabrerce and Stenogramme interrupta, thrown up 

 after storms. Mr. F. W. Smith for many years collected marine alga? 

 at Falmouth, but unfortunately did not examine them microscopically,
