 here some alpine mosses, as the piliferous variety of Trichosto-

 Dicrmium ovale^ Orthotrichum rupincola^ TorUda mucronifb-

" 23d June. — The two principal excursions to be made around 

 Mont Louis are to the Vallee d''Eyne, and to the mountain of 

 Cambredazes. The unpleasant weather we experienced yesterday 

 had induced us to postpone our visit to the first of these ; but 

 this morning the sun shone forth so clearly, and the sky was so 

 pure, that we almost regretted the relinquishing a plan we had 

 formed even before our departure from Prades ; the specimens, 

 however, we had procured during these two last days would be 

 all the better, and certainly nothing the worse, of this delay. 

 We now also, that the hazy weather had left us, began to see 

 somewhat about us. The cabanasse is situated in a large tract 

 of alpine meadows. On the north is a low hill, with the fort of 

 Mont Louis on its summit, and to the south the mountain of 

 Cambredazes, celebrated in the Flora of the Pyrenees. This 

 does not appear of great height ; but that may be partly owing 

 to our \ye\ng at present at a considerable elevation, most proba- 

 bly much more than 4000 feet above the sea : indeed, the plants 

 we had observed, particularly the appearance of the Rhododen- 

 drum ferrugineum and Juncxis trifidtis (which were found to- 

 day north of the fort), the coldness of the springs (about 4s5*' 

 Fahr. or scarcely 6° Reaum.) indicate at least that altitude, as 

 well as does the sharpness of the air, which, when we were not 

 exposed to the sun, we felt to be tolerably chill. To the west 

 of us is French Cerdagne, arid indeed not a mik; from the ca- 

 banasse, the mulcts flow into Spain, 



" The 24th we undertook the botanical examination of tlie 

 Vallee d'Eyne, accompanied by a mule loaded with as much 

 provisions as we thought might suffice for three days, with our 

 cloaks, and with two or three reams of paper. The first day

 which and Grimmia sjnralis I can find no difference.
