Abstract

ON Sunday, August 17, M. Janssen ascended to the Grands Mulets, and next day he reached a hut called the Cabane des Bosses, which an Alpinist, M. Vallot, of Paris, has erected at a point about 400 metres below the summit of Mont Blanc. According to the Paris correspondent of the Times, the second day's journey was made in a sledge, drawn and pushed by twenty-two guides. Tuesday, Wednesday, and Thursday M. Janssen spent in a part of the hut which M. Vallot has fitted up as a scientific laboratory. On Friday, as the weather was very clear, M. Janssen had his sledge dragged up to the summit of the mountain to complete his observations. At the ridge of the Bosses, which is almost vertical, and bordered on both sides by beds of snow ready to fall in avalanches at the slightest motion, the guides begged him to leave the sledge. He did so, but after taking five or six steps he fell exhausted on the snow and had to return to the sledge. He went back to the Grands Mulets the same day, and on the following Sunday he reached the Hôtel de Mont Blanc, and rejoined Mme. and Mdlle. Janssen, who had watched all his movements through a telescope. The results obtained by M. Janssen on this occasion confirm those to which he was led by his previous observations at the Grands Mulets.
