Tesla, Nicola
Nicola (1857-), a noted electrical engineer. Tesla was born in Austrian Croatia. He was educated at Gratz. Prague, and Budapest. He was employed for some time by his native government in the department of telegraphy. He went to Paris as electrical engineer for a lighting company, then crossed the Atlantic to the United States , believing this to be a promising field for electrical expansion. For a time Tesla was engaged by the Edison Company. Later he set up a laboratory for himself in New York City. Tesla is noted as an original investigator in electrical fields. He has contributed a number of able articles to the scientific periodicals, and has invented numerous improvements in dynamos, induction coils, arc lamps, incandescent lamps, steam engines, etc. He had a hand in the installation of the machinery used to transmit power from Niagara Falls. Among American electrical engineers Tesla ranks second only to Thomas Edison.

Test Acts
in English history, acts prescribing religious tests as a requisite for holding office. They were designed to prevent all but members of the established, that is to say, the Episcopal church , from holding office. The term applies more directly to two English statutes. The act of 1673 required magistrates to take oaths of allegiance to the crown, acknowledging the king or queen to be the lawful head of the church. This act was directed particularly at the Catholics, who recognized the pope only as the earthly head of the church. The act of 1685 prescribed a similar oath for all offices both in the army and in the civil service . The acts had not been on the statute books very long before the public became ashamed of them. The acts were evaded. Persons not members of the Church of England took office, and Parliament passed an act annually pardoning them for doing so. In 1829 the acts were formally repealed. The universities also had special tests which they imposed upon students applying for admission, and more particularly upon those who sought positions as instructors.

Test Papers
in chemistry, are made by dipping unsized paper into an alcoholic solution of a vegetable coloring matter which changes color when exposed to the action of an acid or alkaline solution. The paper, after being gently dried, is cut into slips of a suitable size. Hence, by dipping the appropriate test papers into any solution, one can ascertain whether it is acid, alkaline, or neutral. Litmus and turmeric are most commonly used as the coloring matters; litmus for the detection of acids, and turmeric for that of alkalies. Test papers are also employed for detecting sulphuretted hydrogen, etc., and for such a purpose the paper must be dipped in the solution of an appropriate substance. Thus acetate of lead paper becomes black' in presence of sulphuretted hydrogen, while starch paper becomes blue when touched with iodine. TESTUDINARIA (so named from the resemblance which the great, rugged, cracked root of the plant bears to the shell of a tortoise), in botany, the elephant's foot or Hottentot's bread, age Dioscoreaceæ, akin to Dioscorea, but with the seeds winged only at the tip, instead of all round. Rootstock above ground sometimes four feet in diameter. Stems occasionally 40 feet long; flowers small, greenish-yellow. T. elephantipes is the common elephant's foot or Hottentot's bread. The rootstock is a large, fleshy mass, covered with a thick bark, cracked deeply in every direction. The Hottentots in time of scarcity made use of the fleshy inside of the root as a kind of yam.
