This model is one of the extempore pieces of apparatus that I designed forthe purpose of illustrating a course of experimental lectures, which weredelivered with the special object of showing that many of the mostimportant of physical phenomena might be illustrated by apparatus ata cost not exceeding a few pounds. The model itself cost less than ashilling, and I made it in about half-an-hour. Since it was made I havefound it useful to illustrate so large a number of cosmical phenomena that Ithought it of sufficient importance to bring before the Institute. A muchlarger number of phenomena may be illustrated by its means than by theexpensive models usually sold for the purpose. Among these are day and TRANS. lilZ. INSTITUTE, J?
