Our firfl; variety entirely accords with the ipeciiiicns in the 

 Linna-an I-lcrbariuin. \Vc found it in great plenty on the rocks at 

 lifracombc. It there fcldom exceeded three inches in' lieioht : it 



O 



grew erecl and compa^l, the branches of the -thickneirs of fmall 

 wire, and fcarcely a ring upon them. Very few of the branches 

 (probably owing to their humble growth and firm texture) had 

 ever fuftered any injury. At Haftings we have found it from three 

 to nearly five inches in height. The plants were all fomewhat 

 diff'ufe and procumbent. The injuries done them (being very much 

 expofed to the force of the waves) were frequent, and the rings (for 

 rnigs are almoft conftantly attendant upon the injuries, at leafl 

 where the injury has not Hopped the farther growth of the j)lant) 

 were obfervable in proportion. As thefe plants grew taller, fo aUb 

 their branches are fomewhat thicker than at Ilfracombe, 



At Cromer in Norfolk we have met with our variety ,3 iaier- 

 ceptus in abundance. We fo call it from all the branches havin'r 

 almoft conftantly thefe annular callofities jud at their laft divifion. 

 It here grows to the height of fix or eight inches, and the branches 

 are all proportionably thicker. In this variety the branches pro- 

 duced after the annular procefs are more pellucid (owing perhaps 

 to the thinnefs of the new tender fubftance) than ufually is feen 

 in the former : but nothing is more common than to fee, in all 

 ftages of growth, the tips of the branches greenilli and of aclearifii 

 .caft. 



Two things arc too flriking not to be mentioned : firft, that thefe 

 rings are never to be feen but at the extremities of the frond, and 

 v/hen the length of the branches makes them more capable of 

 being broken off; and farther, that no one branch has fcarcely ever 

 more than one ring. All fubje6ls in nature are endued with a power 

 of repairing ordiuaiy injuries ; but reparation is the confequence of
