localities may be expected to reward a diligent search. Link states 
that it is found near Gilphead in the west of Scotland, but though 
not unlikely, we do not find his statement confirmed. In the 
Channel Islands, as at Sark, Guernsey, and Jersey, it again occurs, 
and at least in the two last-mentioned in profusion. Its favourite 
localities are the crevices of rocks and old walls, the sides of wells, 
and the shafts of deserted mines. Mr. N. B. Ward has favoured 
us with an account of a magnificent tuft which he found, along 
with others, almost closing the mouth of a well, in the island of 
Jersey; the fronds of this plant were a foot or more in length, 
and the plant bore no fewer than one hundred and twenty per- 
fectly fresh fronds, besides the remains of sixty or seventy others 
in various stages of decay. Mr. Ward found it most abundant in 
the western side of the island, varying much in situation and in 
‚size: on dry fully exposed walls, scarcely more than a couple of 
inches long; while on the densely-shaded dry sandstone banks, and 
when lining the interior of wells, it grew upwards of a foot in 
length. Mr. Watson gives it an altitude of 600 feet in Wales; 
but Mr. Bennett reports finding it at an elevation of 700 feet, 
at Barmouth. The Carnarvon or Denbigh habitat is, no doubt, 
equally elevated. The following are some of the stations which are
