[From Gr. βάρος ( baros ) = weight, μακρός (makros) = long, and μέτρον (metron) = measure.] An instrument for ascertaining the weight and length of newborn infants. IMG:content-1075.jpg:[graphic] IMG:content-1076.jpg:[graphic] word. Latham derives it from binocle, and Max Müller from Ger. brille, O. Ger. berulem , a corruption of beryllus . Compare Dan. brems, brand gars = barnacles as defined below, and Fr. besicles = spectacles.] Generally in plural : 1. Farriery: An instrument put upon the nose of a horse when he will not stand to be shod or surgically operated upon. It consists of two branches, joined at one end with a hinge, and is generally made of iron. 2. Ord. Lang. A cant term for spectacles, these resembling the instrument described under No. 1.

Ger. barometer; Fr. baromètre ; Sp., Port., & Ital. barometro; Gr. βάρος ( baros ) = weight, and μέτρον ( metron ) = a measure.] An instrument used for measuring the atmospheric pre ure. The discovery that this pre ure might be counterpoised by a column of mercury standing as high in proportion to the thirty-four feet that water in similar circumstances stands, as the specific gravity of water is to that of mercury (the ratio or proportion, it will be perceived, is an inverse one), was made at Florence in the year 1643 by one of Galileo's pupils, the celebrated Torr i cell i, but was not quite complete when he died, in 1647. The most common form of barometer is what is called a Cistern Barometer . It consists e entially of a straight gla tube about thirty - three inches long, filled with mercury, and dipping into a cistern of the same metal. It is affixed to a mahogany stand, on the upper part of which is a graduated scale to mark the height in inches at which the mercury stands. When complete, a thermometer stands side by side with it to note the temperature at which the pre ure of the atmosphere is tested. In Fortin's barometer the base of the cistern IMG:content-1077.jpg:[graphic][merged small] is made of leather, and can be raised or depre ed by means of a screw; a constant level of the mercury from which to measure the zero 444 cative of rain.
