BAGN^RES-DE-BIGOREE. 



At Bagneres-de-Bigorre, I had the kind and able assistance of J. Maxwell- 

 Lyte, Esq., an Englishman of scientific attainments, who has resided in 

 Bagneres for eleven years. The temperature of the springs was observed very 

 carefully by means of several instruments. I used, as on all occasions, my ther- 

 mometer D. The instruments employed by Mr Lyte were A, a thermometer 

 made by Greiner of Berlin, and sold in London by Horne & Co. of Newgate 

 Street. The degrees on this instrument were marked, both in Reaumur and 

 Fahrenheit, forty-five of the latter corresponding to an inch of my pocket tape. 

 B, a thermometer made by Fastee of Paris, with a maximum index ; this instru- 

 ment had twelve Centigrade degrees to the inch of. my tape. C, a thermometer 

 (lent for the occasion by M. Soubervie, medical inspector at Bagneres) by 

 FastrS of Paris, having eight degrees to the inch of my tape. Before leaving Mr 

 Lyte's house, we dipped three of the thermometers (we had not then got M. 

 Soubervie's instrument) into a large beaker, containing cool spring water. The 

 result was as follows : —

 25-70 Cent. = 78-26 



In the following remarks, I shall speak only of the temperature as recorded 

 by thermometer D and the maximum thermometer, as there was less difference 

 between them than between the other instruments and mine ; but I have kept a 

 record of the temperature afforded by all the instruments. 



We first visited the establishment known as Le Salut, between six and seven 

 hundred yards from the town. There we observed the temperature of three 

 springs, namely: —
