XVI. Fernet. 
A. Geological Position . — The springs of Vernet, at the foot of the Mont Canigou, 
are the best known in the Eastern Pyrenees. Their position has already been ad- 
verted to, occupying the outposts of the patch of stratified rocks upon which Ville- 
franche is situated, and which is surrounded by granite. Granite is the predominant 
rock near Vernet ; limestone, however, occurs, and contains (in some instances in 
great quantities) compact sulphate of barytes *. The aspect of the Canigou from 
Vernet is most imposing, and the precipitous nature of the ravines in the neighbour- 
hood is strongly indicative of convulsive action. The position of the ruined monastery 
of St. Martin du Canigon illustrates this statement. 
B. Specialties of the Springs . — There is only one considerable thermal establish- 
ment at Vernet, though within a few years some adjacent springs have also been 
turned to use. The springs are particularly described by Anglada ; but to prevent 
all ambiguity, I shall refer to a sketch of their present arrangement.

The spring A flows into the bath of the cabinet No. 4, and its temperature was 
measured there. Its point of rise was stated to me to be at a , about four feet distant. 
This is the hottest spring, and the “ Source Interieure” of Anglada. It is moderately 
copious. B represents the point of influx of a second spring, entering the building at 
a considerable height above the floor by a baked-earth conduit, which conveys it from 
the rock, which was stated to me to be only two or three feet distant. It is tolerably 
copious, and probably corresponds with “ Source No. 1.” of Anglada. The buvette 
appears near the middle of the western wall of the building. It is quite insignificant. 
A new spring has lately been opened a little to the south-east of the baths, which, 
* The eastern part of the Pyrenees seems to have been less carefully examined by Charpentier than any 
other ; and I suspect that his map is considerably imperfect.
