 size and somewhat in general appearance to 8. rvfescens.

A very singular species of a most soft and silky texture, growing in 

 dense tufts, apparently upon the trunks of decaying trees. The colour is 

 a very pale riddish green. The steins are from one to two inches long, 

 thickly clothtd with leaves, which are remarkable in being formed almost 

 entirely of those large pellucid and even transparent cellules which exist 

 only at the base of the leaves in other species. The opaque portion of the 

 leaf is almost wholly confined to the very extremity, or running down for 

 at most one third of the leaf, gradually quitting the nerve and disappear- 

 ing at the margin. The seta is abcut half an inch long, extremely slen- 

 der, yellowish. The capsule shortly oblong, at first yellowish, afterwards 

 red-brown. The lid has a subulate point equal in length to, or longer 

 than the capsule. Calyptra almost white, enveloping the capsule, but we 

 have not seen it in a mature state. 



Art. VI. — Some Account of the Climate, §c. of the North of 

 France, collected partly from Observation, partly from a free 

 Communication with the Inhabitants of various ranks. 

 Written during a Residence in that Country, for the use 

 of a Friend in Britain. By H. H. Bi.ackadder, Esq. 

 Surgeon. 



The northern part of France, distinguished more exclusively 

 by the name of French Flanders, comprehends about 60 

 square leagues, or 180 square miles, — extending N. E. to W., 

 from Dunkirk to Calais, about nine leagues, and N. to S. E., 

 from Gravelines to Cassel, about eight leagues. This tract 

 of country forms one extensive level plain, which was, be- 

 yond all doubt, at some remote period occupied by the sea. 

 The insulated hill on which Cassel stands, and which rises 

 from five to six hundred feet above the level of the plain, was, 

 at one time, bathed by the sea, from which it is now distant 

 about six leagues, — and there arc monuments which seem to 

 indicate that vessels could, in former times, reach even to St 

 Omer, which is eight leagues from the present shore of the 

 English Channel.
