8/32 1640 499.86 10 ............... 1645 501.39 These figures show that this lake exceeds in depth the deepest of the Swiss lakes (the Lake of Geneva), which has a maximum depth of 334 meters. On the Italian side of the Alps, however, Lakes Maggiore and Como are said to have depths respectively of 796.43 and 586.73 meters. These two lakes are so little elevated above the sea that their bottoms are depressed 587 and 374 meters below the level of the Mediterranean. By means of a self-registering thermometer (Six's) secured to the sounding-line, a great number of observations were made on the temperature of the water of the Lake at various depths and in different portions of the same. |
