BAGNERES-DE-LUCHON. 



I spent several hours in the galleries at Luchon, and observed the tempera- 

 ture of many, but not of all, the springs. My notes of the temperatures are 

 before me now, but I scarcely think they are calculated to fulfil the present 

 object of determining whether the temperature of these springs be constant or 

 not. So much engineering skill has been spent upon the excavations at Luchon 

 that I suppose Principal Forbes, who visited the place in 1835, would scarcel}'^ 

 recognise the places where he dipped his thermometers; and, as still further 

 exploration is determined upon, probably in a short time the places where I made 

 ray observations will be obliterated. Another reason why I am not anxious to pub- 

 lish my observations made at Luchon is, that I had no second thermometer whereby 

 to check the reading of my own. Unfortunately Dr Lambron, from whom I re- 

 ceived much attention and kindness, had left his thermometer in Paris ; and M. 

 FoNTAN, the talented inspector, from whom I also received much kindness, had in 

 like manner left his thermometer at his winter residence. I was accompanied 

 into the galleries by an intelligent workman, who afforded me all the assistance 

 in his power ; but I am not sure that he clearly apprehended my questions, though 

 he never failed to make a very spirited reply. For the temperatures of the springs 

 I must refer to the works of M. Fontan, Dr Lambron, and M. Ftlhol. 



I spent a short time at the baths of Ussat (Ariege), and noted the temperature 

 of the springs. I was kindly aided b}^ Dr Ourgaud, the medical inspector, in 

 whose work will be found a notice of the temperature, and of other matters of 

 interest connected with the mineral water.
