Abstract
A THERMOMETER which is capable of regulating the temperature of a room with considerable accuracy, or of keeping a continuous record of the temperature, is frequently required in laboratory work. Such a thermometer is described in the present article. Although there is little essentially new in its construction, the details on which success depends are the result of considerable practical experience, and as the manufacture of such an instrument should be within the powers of most laboratories employing a mechanic, it has been thought desirable to publish an account of it.
