, the name given to a viscous exudation of the See also:holly-See also:- TREE (0. Eng. treo, treow, cf. Dan. tree, Swed. Odd, tree, trd, timber; allied forms are found in Russ. drevo, Gr. opus, oak, and 36pv, spear, Welsh derw, Irish darog, oak, and Skr. dare, wood)
- TREE, SIR HERBERT BEERBOHM (1853- )
tree, used for snaring birds and known as " See also:bird-See also:lime." In See also:chemistry, it is the popular name of See also:calcium See also:oxide, CaO, a substance employed in very See also:early times as a component of mortars and cementing materials
.
It is prepared by the burning of See also:limestone (a See also:process described by Dioscorides and See also:Pliny) in kilns similar to those described under See also:CEMENT
.
The value and subsequent treatment of the product depend on the purity of the limestone; a pure See also:- STONE
- STONE (0. Eng. shin; the word is common to Teutonic languages, cf. Ger. Stein, Du. steen, Dan. and Swed. sten; the root is also seen in Gr. aria, pebble)

- STONE, LUCY [BLACKWELL] (1818-1893)
- STONE, MARCUS (184o— )
- STONE, NICHOLAS (1586-1647)
stone yields a " See also:fat " lime which readily slakes; an impure stone, especially if See also:magnesia be See also:present, yields an almost unslakable " poor " lime

white amorphous substance, which can be readily melted and boiled in the electric See also:furnace, cubic and acicular crystals being deposited on cooling the vapour
.
It combines with See also:water, evolving much See also:heat and crumbling to pieces; this operation is termed " slaking " and the resulting product " slaked lime "; it is chemically See also:equivalent to the See also:conversion of the oxide into See also:hydrate
.
A See also:solution of the hydrate in water, known as lime-water, has a weakly alkaline reaction; it is employed in the detection of carbonic See also:acid
.
" See also:Milk of lime " consists of a cream of the hydrate and water
.
Dry lime has no See also:action upon See also:chlorine, See also:carbon dioxide and See also:sulphur dioxide, although in the presence of water See also:combination ensues
.
In See also:medicine lime-water, applied externally, is an astringent and desiccative, and it enters into the preparation of linamentum calcis and carron oil which are employed to heal See also:burns, See also:eczema, &c
.
Applied internally, lime-water is an antacid; it prevents the curdling of milk in large lumps (hence its See also:prescription for infants); it also acts as a gastric sedative
.
Calcium phosphate is much employed in treating See also:rickets, and calcium chloride in haemoptysis and haemophylia
.
It is an antidote for See also:mineral and oxalic acid poisoning
