There tanti a.] The act or state of expecting; something ex- are three varieties, the solid , the hollow , and the foli- ated. There is no bone that may not become the seat of this disease, though some are much more subject to it than others. No external treatment is of any benefit in this disease. When it is nece ary that they be re- moved, and it can be done with safety, it is effected by sawing or cutting. (Bot.) A disease to which the roots and stems of trees are subject, when knots or large tumors are formed upon or among the wood. It is caused by a stoppage of growth on the one hand, and an attempt at exce ive development on the other. These knots are sometimes called knaurs , and from them some of the most beaut i- ful wood used by cabinet-makers is obtained. Exoter'ic, or Exoter'ical, a.

To open or spread out; to spread; to dilate; to extend in bulk or surface; to enlarge. Expand'ed, p . a. Opened; spread out; extended; dilated: enlarged; diffused. Expand'ing, p.a. Opening; spreading out; extend- ing; dilating; diffusing. Expanse', n . [Lat, expansum , from expando.] That which is spread or stretched out; a surface widely ex- tended; extent; a wide extent of space or body. Expansibility, n. The capacity of being expanded; capacity of extension in surface or bulk. Expan's ible, a . [Fr.] Capable of being expanded or spread; capable of being extended, dilated, or diffused. Expan's ibly, adv . In an expansible manner. Expan's ile, a. Capable of being expanded; produc- ing expansion. Expansion, n. [Fr.; Lat. expansio.) (Physics.) The enlargement or increase of bulk in bodies; gener- ally the effect of heat. It is the result of raising the temperature of all bodies, solid, liquid, and aëriform. The E. of solids is comparatively small, the metals being the most affected by heat and cold. It is nece ary to make provisions for E. in metallic structures, other- wise destructive effects must ensue, even from the changes in the usual range of atmospheric temperature. E. in metals and liquids is variable, some expanding under the influence of the same temperature more than others, and the rate of E. is not generally uniform for equal increments of heat. In most cases, all bodies contract when the temperature is lowered; but there is a remarkable exception to this rule in the case of water, which begins to expand when lowered to 40° Fahr. The power evolved in the E. of water is very great. (See WATER.) A bra globe having a cavity an inch in diameter can be burst by filling it with water and freezing, when the absolute force nece ary to pro- duce a like result is equal to 27,720 lbs. weight. Aëri- form bodies are the most expansible forms of matter, and they all expand and contract alike. As examples of E. , the expansibility of mercury is applied in the construction of the common thermometer ( q . v.); and in consequence of the E. or contraction of their pendu- lums and balance-wheels, clocks and watches go faster in cold weather, and slower in hot. - See PENDULUM. Expansion-joint, n. ( Mech .) The stuffing-box joint connecting the steam-pipes, so as to allow one of them to slide within the enlarged end of the other when the length increases by expansion. Expansion-valve, n. ( Mech . ) An auxiliary valve placed between the slide-valve and the steam cylinder; it is worked by a cam or other contrivance, so as to cut off the steam at a given period, and cause the remainder of the stroke to be performed by expansion. Expansive, a . [Fr. expansif.] That has power to expand; that expands; diffusive. Expanʼsivene , n . The quality or capacity of being Ex parte. [Lat., of the one part.] ( Zaw .) Proceeding from only one part of a matter in question. Expatiate, v . n. [Lat. ex, out, and spatiari , to spread out.] To get out of the course; to move about; to rove at large; to enlarge in discourse or writing; to be copious in illustration. Expatriate, v. a. [Fr. exp a trier, from Lat. ex , and patria , country.] To expel or remove from one's coun- try; to banish; to exile. Expatriation, n .
