become as complete a polype as one that bad never been 

 cut : they expanded, they contracted, they moved from place 

 to place. 



Still he was not satisfied, and he continued to study them, 

 in the hope that he might discover some other properties. 

 According to what he proposed, when he made the experi- 

 ment of cutting them, he should now have concluded that 

 they were plants, as the two cuttings or slips had produced 

 two perfect polypes ; but from the spontaneity of their 

 movements he was rather disposed to regard them as animals. 

 As yet he did not know how they multiplied ; and having a 

 great number of them in a vase together, his attention was 

 turned to this. At last he discovered one about to produce 

 a little one. At first it was Hke a small green bud on the 

 body; it rapidly increased in size, sent forth arms, or tenta-

 polype might be a plant, or rather an animal plant, holding 

 a middle rank betwixt the two, partaking of tlic nature of
