Mr. Turner's Descriptions of Eight New British Lichens. 137 



the subject an attention the most superficial, to be so fully 

 agreed, that there is no occasion for a single argument to be 

 employed : were any necessary, the most substantial one would 

 be found in the number of British species, which is already 

 known to amount to 350, which is almost daily increasing, and 

 which comprehends various tribes of a nature the most dissimi- 

 lar to each other. It only remains for me, therefore, to express 

 my obligations to my friend Mr. Borrer, who has furnished me 

 with the materials of the present paper, who has applied himself 

 to the study of the indigenous Lichens with a zeal and success 

 which I believe to be altogether unrivalled, and whose opinions, 

 I am happy to add, coincide with my own.
