[Footnote 73: The true _Cimetière des Bourguignons_ is the enclosure where René, the victor of Nancy, buried the Burgundians who fell on the sad Sunday when Charles the Bold went down before the deaf châtelain Claude de Bagemont.] [Footnote 74: Neither of my companions, I fear, would have acted as Sejanus did, when another emperor was in danger of his life in the cave on the Gulf of Amyclæ.

Ann. iv. 59.)] [Footnote 75: Water reduced to a temperature below 32° without freezing, begins to freeze as soon as a crystal is dropped into it, the ice forming first on the faces of the crystal.] [Footnote 76: Water attains its maximum of specific gravity at 40°. Below 40° it becomes lighter.] * * * * * CHAPTER XII. THE GLACIÈRES OF THE BREZON, AND THE VALLEY OF REPOSOIR. The bill _à la Parfaite Union_ was as small as the accommodation at that _auberge_, and it was an immense relief to get away from the scene of my sufferings. The path to Bonneville lies for the earlier part of the way through pleasant scenery; and when the highest ground is reached, there is a lovely view of the Lake of Geneva, which may be enjoyed under the cool shade of a high hedge of trees, in the intervals of browsing upon wild strawberries. But after passing the curious old town of La Roche, two hours' walk from Thorens, the heat and dust of the dreary high road became insupportable; and no pedestrian who undertakes that march with a heavy knapsack, under a blazing noonday sun, will arrive at Bonneville without infinite thankfulness that he has got through it. The road is of the same character as that between Bonneville and Geneva, and that will sufficiently express its unpleasantness in baking times of drought.
