constructed at a distance of 15 metres (=49 213 English feet) from the griffon.

 Broca 47-50 Cent. = 117-50 Fahr. 



Petit St Sauveur. — The temperature of this spring was taken at the griffon.

These springs issue from metamorphic schist. We visited them in the fol- 

 lowing order : — 



Cesar. — We observed the temperature of this water at three points, — namely, 

 at the griffon ; at the humtte in the building near the source (distance of this 

 buvette from the griffon 60 metres =196-854 English feet) ; and at the burette of 

 the establishment in the town (distance of this burette from the griffon 350 metres 

 = 1148-350 English feet). The temperature of the water at the several points of 

 observation was as follows : —
