n.
A symbol expressing thirty, as 30, or XXX.
n.
A mean proportion, medial sum or quantity, made out of unequal sums or quantities; an arithmetical mean. Thus, if A loses 5 dollars, B 9, and C 16, the sum is 30, and the average 10.
n.
A rare metallic element, found in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarcable for its low melting point (86/ F., 30/C). Symbol Ga. Atomic weight 69.9.
n.
The sixtieth part of an hour; sixty seconds. (Abbrev. m.; as, 4 h. 30 m.)
n.
A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0¡ C., found abundantly in both the animal and vegetable kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40¡ C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain.
superl.
Prolonged, or relatively more prolonged, in utterance; -- said of vowels and syllables. See Short, a., 13, and Guide to Pronunciation, // 22, 30.
n.
A device, consisting of a pipe or tube bent so as to form two branches or legs of unequal length, by which a liquid can be transferred to a lower level, as from one vessel to another, over an intermediate elevation, by the action of the pressure of the atmosphere in forcing the liquid up the shorter branch of the pipe immersed in it, while the continued excess of weight of the liquid in the longer branch (when once filled) causes a continuous flow. The flow takes place only when the discharging extremity of the pipe ia lower than the higher liquid surface, and when no part of the pipe is higher above the surface than the same liquid will rise by atmospheric pressure; that is, about 33 feet for water, and 30 inches for mercury, near the sea level.
v. t.
Intellectual ability, natural or acquired; mental endowment or capacity; skill in accomplishing; a special gift, particularly in business, art, or the like; faculty; a use of the word probably originating in the Scripture parable of the talents (Matt. xxv. 14-30).
