82 Mr. R. Spruce on the Musci and Hepatice of the Pyrenees. 
Cryptogames récemment découvertes en France,” &e. Most of 
these I have had the opportunity of examining. In 1835, Dr. 
Grateloup began to publish in the ‘ Actes de la Société Lin- 
néenne de Bordeaux,’ tom. vii., a ‘‘ Cryptogamie Tarbellienne, 
ou Description succincte des Plantes cryptogames qui croissent 
aux environs de Daz, dans le Dépt. des Landes,” in which were 
to be comprised all the Cryptogamia growing within 25 leagues 
of Dax, a district which would include the extreme Western Py- 
renees ; but it proceeded no farther than the publication of the 
Characeze, Filices and Hepaticz, for specimens of most of which I 
am under obligation to Dr.Grateloup. About the year 1843, MM. 
Philippe and de Lugo, two botanists residing at Bagnéres-de- 
Bigorre, began to collect the mosses and Hepaticee of the neigh- 
bouring mountains, and on the occasion of my visit to that city, 
two years afterwards, they put into my hands, without reserve, 
specimens of all they had succeeded in finding. A few mosses 
have also at different times been gathered in the Pyrenees by 
MM. des Moulins, Durieu, Gaston-Sacaze, and probably by others 
of whom [ have not heard, and of whose labours I cannot there- 
fore make that honourable mention which is their due. In 1845 
came my own visit to the Pyrenees, undertaken principally 
(though not solely) for the purpose of studying the Musci and 
Hepatic, and extending through a period of nearly eleven 
months. It will not be without use if I here briefly retrace my 
steps, as some repetition will be thereby avoided, and an oppor- 
tunity will be afforded of indicating the position of certain loca- 
lities, the names of which are of frequent recurrence in my cata- 
logue, though too obscure to be found in an ordinary map*. 
I arrived at Pau, the chef-liew of the Dept. of the Basses- 
Pyrénées, and the ancient capital of Béarn, in the early part of 
May 1845, and my first herborization in the Pyrenees was made 
on the 13th of the same month. My excursions comprised, be- 
sides the woods, &c. adjoining the town of Pau, the villages of 
Jurancgon, Gélos, Rontignon and Narcastet, lying on the south- 
ern bank of the Gave de Pau, with the valleys running up from 
them to the southward, among what may be called the skirts of 
the Pyrenees ; and the village of Bilhéres, lying south of the same 
river. From the 29th to the 31st were devoted to a visit to 
Oloron, at the entrance of the Vallée d’Aspe, along which runs 
one of the most frequented roads into Spain. On the 11th of 
June I again left Pau for St. Sever, in the Landes, on a visit to 
Dr. Léon Dufour, the eminent naturalist, where eight days were 
usefully spent in exploring the neighbouring /andes, especially
