The pressure is estimated by means of a mercury or an aneroid manometer. A stethoscope is normally used in conjunction with the instrument to listen to the blood pressure sounds (a stethoscope is not needed with an electronic sphygmomanometer).
ObjectID: 171. Description Edit | History. Chess is a two-player, abstract strategy board game that represents medieval warfare on an 8x8 board with alternating light and dark squares. Opposing pieces, traditionally designated White and Black, are initially lined up on either side.
According to Taylor, the game of chess was the invention of some Hindu who devised a game of war with the astapada board as his field of battle. From the reference to the game in the Rig Veda and the Arthava Veda and in the Buddhist and Jaina books, it must have been very popular in ancient India.
