Heat transmission through insulating materials . be -een in the ,the only source of heat to the inner bl~ck ofice is theough the test ^cimen. The e^fertlvearea of transr^issT on is that directly beneaththe inner ver^cel. r/ieltage from the crushed iceis discharged to waste. The aislt-^re of the ouredistilled ice is carefully weighed to onethousandth of a pound. The heat trans-^ission through the edgesof the -material do not effect the inner blockof ice because the surface in -contact with theinner chamber is only one-fourth that of thetotal area of the soecirnen. In the Voorhees machine we have heat trans- purely by conduction. There are noradiation losses. Therefore we have only com-parative results of the materials inder test. Details of A^^paratus. A - Distilled ice. B - Inner G - Crashed ice. D - Insul^tion. E - Testing G - Cooper plate. H - Girciilating v;ater. I - Insulation. J - Thermometer for inlet ^vater. K - Bolts. L - Pipe for -outlet water. M - Therrnometer for outlet
