1. Source de la Montague. — The temperature of this spring was taken at its 

 source in a gallery, excavated at a little distance from the building. 



2. Source de V Inter ieur. — Temperature taken at the hutette in the building, 

 the distance from that point to the actual source, as I understood, being about one 

 metre. 



3. Source de la Pompe. — Temperature taken at the buvette in the building, 

 being, as I understood, close to the griffon. 



The temperature of the three springs was as follows : — 



Source de la Montagne, 

 La Buvette de I'lnterieur, 

 Source de la Pompe, 



Afterwards, accompanied by a workman to remove the coverings, we visited 

 the sources of the springs which supply the principal establishment situated in the 

 town. We visited the springs in the following order : — 



1 . Souixe du Platane. — At this spring we could easily read the thermometers 

 whilst immersed in the water. 



2. Source du Foidon. — Here the water was too far below the floor of the 

 gallery to permit of our reading the thermometers accurately whilst in the water. 

 We therefore placed the instruments in a quart bottle, which was lowered by 

 means of a cord into the water, filled, and allowed to remain several minutes. It 

 was then raised, and the thermometers were immediately read before their re- 

 moval from the bottle. 



3. Source du Dauijliin. —At this spring we could readily read the instruments 

 whilst immersed in the water. 



4. Source de la Reine. — The approach to this spring is not so easy as to the 

 others. We were able to read the instruments distinctly whilst immersed in the 

 water. We also took the temperature of the water of La Reine at the huvette in 

 the establishment ; the distance between the latter point and the actual source 

 where we had previously observed it, being, as I understood, about 100 metres 

 (328 English feet). 



5. Source de Salies.~-'W\\'s> spring rises in the open space, about twenty paces 

 from the right-hand corner of the establishment (the observer looking at the front 

 of the building). At present the spring is open, half a dozen steps leading down 

 to it ; but it is proposed to extend a wing of the establishment over it. 



The temperatures observed were as follows : —
