A light vapor, suspended in the lower regions of the air, concealed from the sight the lowest and most remote objects, such as the plains of France and Lombardy; but the whole surrounding assemblage of high summits appeared with the greatest distinctness. M. de Saussure descended with his party, and the next morning reached Chamouny, without the smallest accident. As they had taken the precaution to wear vails of crape, their faces were not excoriated, nor their sight debilitated. The cold was not found to be so extremely piercing as it was described by Dr. Paccard. By experiments made with the hygrometer, on the summit of the mountain, the air was found to contain a sixth portion only of the humidity of that of Geneva; and to this dryness of the air, M. de Saussure imputes the burning thirst which he and his companions experienced. The balls of the electrometer diverged three lines only, and the electricity was positive. At times the air seems filled with electricity. A recent traveler (1854) says, that, in the night, his guide having come out from the cabin of the Grand Mulets, saw the ridges of the mountain apparently all on fire. He immediately communicated what he had observed to his companions, who all rushed to assure themselves of the fact, and then they saw that through the electricity generated by the tempest, all the rocks of the Grand Mulets were illuminated. They found the same phenomenon on their own persons. When they raised their arms, their fingers became phosphorescent. M. de Saussure found it required half an hour to make water boil, while at Geneva fifteen or sixteen minutes sufficed, and twelve or thirteen at the seaside. None of his party discovered the smallest difference in the taste or smell of bread, wine, meat, fruits or liquors, as some travelers have pretended is the case at great hights; but sounds were of course much weakened, from the want of objects of reflection. Of all the organs, that of respiration was most affected, the pulse of one of the guides beating ninety-eight times in a minute, that of the servant one hundred and twelve, and that of M. de Saussure one hundred and one; while at Chamouny, the pulsations respectively were forty-nine, sixty, and seventy-two. A few days afterward, Mr. Beaufoy, an English gentleman, succeeded in a similar attempt, although it was attended with greater difficulty, arising from enlargements in the chasms in the ice. A late traveler, wandering amid the same sublime scenery that has been described, says:
