A CHEAP AND INGENIOUS ICE MACHINE.
M. Tonelli, we are told by the " Scientific Review," has just devised a new ice-making machine. The inventor calls it glacier roulante. It is a simple metallic cylinder mounted on a foot. The salt of soda and salt of ammonia are added in two operations ; the smaller cylinder containing the water to be frozen is introduced into the interior, and the orifice is closed by an indiarubber disc, and then with a cover, fastened with a catch ; the cylinder is then placed in a sac, or case of cloth, and is made to roll on the table with a slight oscillatory movement given by the hand. After a lapse of ten minutes, the water in the interior of the cylinder becomes a beautiful cylinder of ice. Nothing is more simple, more economical, or more efficacious, than the new glacier roulante, which costs us 10f., and gives us, moreover, what could not hitherto be obtained with an apparatus containing, freezing mixtures — the means of freezing a decanter of water or a bottle af champagne. The apparatus, in a case, packed for travelling, with twenty kilogrammes of refrigerating materials and a measure, costs at present only £1.
