The holes wereintended to extend within 1 inch of the outer and inner surfaces ofthe wall and the roof, as indicated in figures 3 and 4. The depthsof the holes for couples 1 and 3 could be measured accurately, andtherefore these couples were put at known depths, as represented in thefigures.

The distances of the ends of the holes for couples 2 and 4from the inner surfaces could not be accurately measured, so thatthe distance given in the figures are only approximate. Each couplewas placed in such a way that the fused junction touched the bottomof the hole. Near the outer surface of the wall the annular spacesaround (he wires of the couples were filled with asbestos packing asdeeply as possible, in order to prevent radiation of heat from the FLOW OF HEAT THROUGH FURNACE EQUIPMENT AND
