THE DISTILLATION FLASKS. The flasks (figs. 4 and 5, p^ in which the mixture of corn and oil is heated are primarily distillation flasks having short necks and specially constructed side tubes. (Fig. lb.) The flasks have a capacity of approximately 1,000 cubic centi- meters. The necks of the flasks have a diameter of 2i centime- ters and are made Avithout a flange and sufficiently heavy to stand tight corking. The side tube, W'hich is 7 or 8 millimeters in internal diameter, is insert- ed approximately 3 centimeters from the top of the neck. The respective lengths of the three arms of the side tube are 6|, 7. and 3 centimeters. The bend between the two long arms is 1^ centi- 99.
