| flint glass | <chemistry> A soft, heavy, brilliant glass, consisting essentially of a silicate of lead and potassium. It is used for tableware, and for optical instruments, as prisms, its density giving a high degree of dispersive power; so called, because formerly the silica was obtained from pulverized flints. Synonym: crystal glass. Cf. Glass. The concave or diverging half on an achromatic lens is usually made of flint glass. Source: Websters Dictionary (01 Mar 1998) |

| Austin Flint | <person> Flint, the son and grandson of physicians, was born in Massachusetts and graduated from Harvard Medical School in 1832. He founded the Buffalo Medical College. Austin became associated with Dr. Samuel D. Gross at the University of Louisville. He was a pioneer user and advocator of the binaural stethoscope, and was called the "American Laennec." This internist described a loud presystolic murmur at the cardiac apex in aortic regurgitation now known as the Austin Flint Murmur (1862). He introduced the terms "cavernous" and "broncho-vesicular respiration." His "Principles and Practice of Medicine" published in 1866 was a leading textbook of medicine for many years. Lived: 1812-1886. (18 Nov 1997) |

| Flint's murmur | A diastolic murmur, similar to that of mitral stenosis, heard best at the cardiac apex in some cases of free aortic insufficiency; it is thought to be caused by the turbulent regurgitating stream from the aorta mixing into the stream simultaneously entering from the left atrium through the mitral valve, causing posterior movement of the anterior leaflet of the mitral valve with transient acceleration of blood flow through the mitral valve. Synonym: Austin Flint murmur. (05 Mar 2000) |
