Figure 50. Belloc sounding machine, invented by Emile Belloc. This machine was designed for raising water bottles and thermometers for studying the lakes of Pyrenee Mountains. It was subsequently used in a more robust form by Andre Delebecque on Lake Leman in 1891 and by Prince Albert I of Monaco off his ship in 1894.
