1913 School Science and Mathematics  
After observing the results of examinations in heat for a number of years the writer has found that, despite every effort otherwise, students get an idea that water, or ice, is the only substance that possesses a heat o'f fusion; and the common answer to the question, "What is a heat of fusion," is, "The amount of heat required to melt a gram of ice." It seemed desirable then, to find an experiment which would make clear the fact that every pure, crystalline substance has a heat of fusion. The

The writer claims no particular originality in the method for the determination of the heat of fusion of tin described below, for it will be found, in various forms, in some of the standard laboratory manuals in physics, but the apparatus is so simple and the results are so gratifying that he feels justified in calling it to the attention of physics teachers at this time.
