Adiantum Capillus-Veneris on Cheddar Cliffs. 
“Observing im a late number of the ‘ Phytologist’ the recorded 
occurrence of Adiantum Capillus-Veneris near Bath, I beg to corro- 
borate the fact of the existence of that fern in Somersetshire, having 
myself, in the year 1851, found a plant or two of it on moist rocks in 
the neighbourhood of Cheddar. I dried a few specimens, but left the 
roots uninjured; and, as they are in an out-of-the-way situation, I 
trust I may find them still there on my next visit to Somersetshire.”

Tents Muir Sands, on the east coast of Fife, where it was discovered 
by Mr. W. M. Ogilvie, on the 27th of August last. It was associated
