    On the day after my return from the moun- tain, I visited on foot Montanvert and the Jardin, returning to the Priory in the evening, a dis- tance estimated at fourteen leagues (a tolerable proof of my not having suffered excessively from fatigue). The observations with the barometer and thermometer at these places, at Geneva, and at the Hospice of the Great St. Bernard,* as well as those already mentioned, are given in the following table :— Eng.
