An air-bath melting point apparatus for micro-quantity of a sample (Fig. 1) was designed with a little modified furnace which had been reported in a previous paper. The sample is placed between two pieces of glass plate (10×75 mm.), and introduced into the furnace in such a way as to place the sample on the mercury bulb of a thermometer. The sample holder is protected from a hot stream of air by a piece of glass plate of 10 mm. width, which is set on the holder at a distance of about 3 mm. The sample is heated intermittently by turning the dial of a bimetal regulator with the proper heater. Table I proved that the rise in temperature of 1° per more than 5 seconds might give a practical constant value in the neighborhood of the melting point.
