The bearings are all plain, which causes a considerable amount of friction ; the centre of gravity of the rotating system is placed very high, which causes vibration, due to imperfect balancing, to be marked. The air resistance at high speeds is somewhat great. These are serious faults, but are capable of improvement. The two-bottle Beimling machine is the only machine on the market, to the author's knowledge, in which the bottles assume a hori- zontal and radial position when rotating ; in the larger sizes the bottles are nearly, but not quite, radial. This position is advan- tageous, as it allows of the most rapid separation of the fat from the acid Leffmann-Beam Machine. Apparatus,—The test bottles consist of flat-bottomed flasks with a sloping upper portion terminating in a graduated neck. The bottles (English make) hold 29 ; the necks are made of glass tube 5-96 mm. in internal diameter, and are so graduated that 80 divisions = 1-475 These dimensions are according to a specification laid down by the author, and differ slightly from those prescribed by Leffmann and Beam. The pipettes used are— 15 for milk, 9 for sulphuric acid, 3 for amyl alcohol mixture, 4-5 for cream, and 10-5 for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Richmond, Henry Droop.
