458 DR R. E. SCORESBY-JACKSON ON THE TEMPERATURE 



Of the six springs in use at Eaux Chaudes, three are conducted into the estab- 

 lishment, and these are they which are affected by the change of position. They 

 are named Le Clot, V Esquirette, and Le Rey. The other three are employed at 

 the several points at which they rise ; they are called Baudot, V Arressecq, and 

 Mainvielle. 



Le Clot. — This spring is received, at its point of emergence, into a reservoir 

 which is hermetically closed. From this reservoir the water is conveyed by two 

 conduits to the establishment — the one leading to the baths, the other to the 

 huvette. The water, doubtless, loses a certain quantity of heat during its passage 

 from the actual source to the huvette ; and I was told, moreover, that, in spite of 

 every effort to preserve it from decomposition, the amount of sulphuret of sodium 

 in the water is much less at the baths and the huvette than at the griffon. The 

 loss of temperature at the huvette I was unable to ascertain, as I had no oppor- 

 tunity of testing it at the griffon. The actual temperature observed by me at the 

 huvette was 9400 Fahr. At the same time, M. de Fietra-Santa read his ther- 

 mometer at 34-50 Cent. = 94-10 Fahr. 



L'Esquirette. — This spring has been divided into two parts by a recent explo- 

 ration into the rock ; they are termed respectively hot and temperate. The hot 

 stream is conducted to a huvette in the establishment, and supplies also, in com- 

 bination with the temperate stream, the baths and douches. The distance between 

 the griffon and the huvette of this source, I was told,* is 30 metres, equal to 

 98-427 English feet. The temperature observed by me at the griffon was 9380 

 Fahr. M. de Pietra-Santa recorded 34*20 Cent. = 93'5(j Fahr. At the huvette 

 I found the temperature to be 92-40 Fahr.; M. de Pietr.\-Santa, 3350 Cent. = 

 92-30 Fahr. 



Le Rey. — This spring rises on the site of the old establishment, and is im- 

 mediately received into a reservoir, whence it is conducted to the new establish- 

 ment. The distance between the griffon and the huvette I did not ascertain. 

 The temperature recorded by me at the reservoir was 91*40 Fahr,, M. de Pietra- 

 Santa at the same time recording 33*00 Cent. = 91-40 Fahr. At the huvette I 

 recorded 90*00 Fahr , and M. de Pietra-Santa 32-00 cent. = 89-60 Fahr. 



Baudot. — The temperature of this spring was taken at the huvette, close to its 

 point of emergence from the granite. My thermometer marked 77-00 Fahr. ; M. 

 DE Pietra-Santa, 2500 Cent. = 77-00 Fahr. 



V Arressecq. — The temperature of this spring was also taken at the point 

 where it leaves the granite. My thermometer marked 7490 Fahr. ; M. de Pietra- 

 Santa, 24-00 Cent. = 75*20 Fahr. 



Mainvielle. — The temperature of this spring was taken at the huvette, which is 



* The distances mentioned throughout are such as vvei'e told me by the gentlemen who 

 accompanied me to the several springs. I had no opportunity of measuring them.
