It is beheved that this is the first at-tempt to take temperature records within the large smoke-tubes at a point such as that denoted l)y I\. The wiring for the instrument is shown in Figs. 1 and method employed was devised by Mr. Kroukovsky, pro-fessor of electro-technics at the High School of Mining atEkaterinoslay. Its essential feature is that, instead of usingsensitive voltmeters in connection with the pyrometer, a com-.
