Abstract

THE countries between the 4oth degrees of N. and S. latitude have in general too temperate winters to admit of natural ice being obtained in any quantity; and yet these are the countries in which it is most required. The high price at which it is sold prevents many people From buying it. It is for the purpose of rendering the supply of this useful and healthful article abundant and cheap that ice-making machines have been devised. These are of three classes, of which we shall give a brief account in order to show the advantages of the new invention, due to the ingenuity of a young Genevese physicist, M. Raoul Pictet.
