在使用为大学新化学实验室购买的仪器时，没有一件比新蒸馏器更令人满意，或者说更成功，这就是本文的主题。在设计这个蒸馏器时，我有两个明确的目标;一个是利用60马力的大锅炉的蒸汽来加热建筑物，另一个是当加热厂的蒸汽不可用时，用煤气制造蒸馏水。蒸馏器用锻铁包裹，内衬石棉，并配有一个浮子，可以自动调节供水管的水流。这是一件很漂亮的仪器，每一个细节都做工精良.本装置的主要部件将通过参考附图而被理解，但几句说明可能是适当的。蒸馏器的容量为7加仑，由重铜制成，锡衬里。它有一个水位计，显示蒸馏器中水的高度，还有一个蒸汽出口和安全阀，V;蒸汽入口通过一个螺旋穿孔的锡管;还有一个出口，O，用于清洁蒸馏器;还有一个重型圆盘煤气燃烧器。有一个精心布置的干燥炉和一个大冷凝器，携带-
IN the use of the apparatus purchased for the new chemical laboratories of the university, no piece has given us more satisfaction, or has been a greater success, than a new still, which is the subject of this paper. In the designing of this still I had two definite objects in view; one, the utilizing of steam from the large sixty horse-power boiler used in heating the building, and the other, a provision for making distilled water with gas, when steam from the heating-plant was not available. The still is encased in wrought-iron, with a lining of asbestos, and is provided with a float which automatically regulates the flow ofwater from the supply-pipe. It is a beautiful piece of apparatus, and the workmanship is excellent in every detail. The essential parts of this apparatus will be understood by con-sulting the accompanying figures, but a few words of explana-tion may be appropriate. The still has a capacity of seven gal-lons, and is made of heavy copper, tin-lined. It has a water-gauge showing the height of the water in the still, also an exit for steam, and safety-valve, V; inlet for steam through a coiled perforated block-tin pipe; also an outlet, O, for cleaning out the still; and there is also a heavy disk gas-burner. There is a conveniently-arranged drying-oven and a large condenser, carry-
