88 ANTIIOZOA IIYDROIDA. 



until the meeting of the British Association at Plymouth, in 1841, 

 when T read one on the Organic Fossils of Cornwall. It is impossi- 

 ble to describe the feeling I rose under ; — that is over long since ; 

 and the only beating of my heart about the British Association now 

 is, that of gratitude towards its members, and of love for their great 

 kindness. I feel the love of and for scientific pursuits strengthen 

 every day ; and I feel that I have taken hold of that which affords 

 every day a ' feast of reason and flow of soul.' "

 as common as the preceding, and is found on all our coasts. 



" This differs," says Ellis, from the preceding, " in being branched 

 out, and in having its capillary ramifications much longer." Never- 

 theless, Ellis deemed them " one species ;" and to this conclusion 

 he was unhesitatingly followed by Pallas and by Dr. Fleming. 

 Lamarck and Lamouroux fell back upon the older opinion of Ray ; 

 but they had not discovered any new diagnostic to support the 

 distinctions they defined, which seem to have been made merely in 

 the indulgence of an analytical spirit. Hence I followed the view 

 of Ellis in the first edition of this work — a view still considered as 

 correct by Mr. Couch. " There are," he says, " two variations of 

 this species which at first would seem to constitute specific dif- 

 ferences, but after many examinations I am inclined to think they 

 are only varieties." I confess myself to remain of Mr. Couch's 

 opinion. 



From a closer examination, Mr. Hassall was the first to say, 

 on apparently better grounds, that these varieties might be really 

 species. He tells us that Ant. ramosa arises " by a single trunk, 

 which subsequently divides and subdivides into numerous branches ;"
