 many, and on being sought with equal acute- 

 ness, were found in England. Three species 

 have been delineated in Engl, Bof. t. 92(y^ 

 1095 and V23S, from the discovries of Mr. 

 Turner and Mr, W. Borrer. The flowers 

 of Mosses, long neglected and afterwards 

 mistaken, were faithfully delineated by Ali- 

 cheli, carefully examined and properly un- 

 derstood by Linnaeus as he rambled over the 

 wilds of Lapland*, and at length fully illus- 

 trated and placed out of all uncertaint}^ by 

 the justly celebrated Hedwig. These parts 

 indeed are still unknown in ferns, or at least 

 no satisfactory explanation of them has 

 reached me, though the seeds and seed- 

 vessels are sutTiciently obvious.
