Olmsted Scientific Co., Chicago, III.\n133\nKYMOGRAPH.\nThis new Kymograph, originally designed for and used in the Physiological Laboratories of the University of Chicago, for making index tracings upon smoked paper, has met with such a flattering reception from numerous other laboratories, that the manufacturers feel justified in claiming for it that it meets all the requirementsex-acted of such an instrument, notwithstanding the fact that its price is much lower than any other now in the market.\nTheKymograph is 55 cm. high, with a base 20x28 cm. Its weight is 15 kilogrammes, thus insuring sufficient firmness against lateral vibrations. It consists of an accurately turned brass cylinder 12.5 cm. in length by 15 cm. in diameter, which is supported by a steel shaft revolving or hardened steel pivots. This cylinder can be easily removed or adjusted vert.-cally by the set screws at each end, It is rotated by a strong spring motor enclosedin the heavy iron base. The speed is uniform and can be regulated by the use of small fans which are slipped over an upright pinion. Three fans are supplied with each instrument. The largest permits the cylinder to make one revolution in ten minutes, the medium one in five minutes, the smallest one in one minute,\nwhile the clockwork running without any fan revolves the cylinder in ten seconds. Any desired speed can be obtained by trimming the ends of the fans as much as may be found necessary. The clockwork is started or stopped by the small button near the base of case as shown in the illustration.\n1199.","page":133},{"file":"p0134.txt","language":"en","ocr_en":"134\nThe Chicago Laboratory Supply & Scale Co.\ncomplete with 100 sheets of Gummed\n1499.
