HOT ICE.

Dr Percy Bridgman, of the Department of Physics at Harvard University, aimuounces ihat he has succeeded in making "hot ice." According to telegraphojl reports from Boston, Massachusetts, the doctor has manufactured some of this remarkable commodity having a temperature of 173 degrees Fahrenheit, and he is confident that he can make it even hotter. Hot ice is produced by putting water under extraordinarily heavy pressure, and at the same time regulating the temperature of the water. The apparatus used includes a hydraulic press and a very thick tube of steel to hold the water. There ,is also a provision by means of jackets on the tube for keeping the contents constantly at any desired temperature in studying the forms of ice. We are told, the Telegraph says, that the doctor kept the steel bottle filled with water and ice until he had obtained a

j pressure of more than 20,0000 atmos1 pheres—that is, over 3000,0001b to the square inch —and a temperature of 173 degrees Fahrenheit. In appearance "hot" ice is similar to the brand in general use.
