WAX, a solid concrete, abounding in the vegetable kingdom, whence it is collected by bees.—In the article Bees-wax, we have stated the manner in which this substance is obtained, and likewise the uses to which it is applied: at present, therefore, we shall direct our attention to the blanching or whitening of wax, and to the process by which it may be artificially extracted from vegetables.
With a view to bleach wax, it is cut in small pieces, melted, and poured into cold water, where it granulates. In this state, it is exposed to the sun and air; melted, and granulated repeatedly; then submitted to the influence of the sun, air, and dew, in the interval between each liquefaction. When the wax is perfectly blanched, it is dissolved for the last time, and cast into flat moulds, in which it is again exposed to the air, for one or two days, in order to render it more transparent.
Wax may be extracted from the leaves and petals of numerous vegetables (see the General Index of Reference); by collecting, bruising, and dissolving them, first in water, and then in alkohol, or spirit of wine, till every other ingredient thai is soluble in these fluids, be completely separated. The residuum is now mixed with 6 times its weight of a solution of pure ammonia: when it has been thoroughly macerated, the liquor must be decanted; filtred; and, while it is briskly stirred, a sufficient portion of sulphuric acid must be gradually added, to super-saturate the alkali. Thus, the wax will be precipitated in the form of a yellow powder; which, on being carefully washed with simple water, and melted over a slow fire, possesses all the properties of bees-wax.

WEANING, is the act of gradually removing an infant from the breast, and habituating it to take common food.
Weaning requires to be conducted with some precaution: it will, therefore, be advisable to inure children to take proper aliment out of a boat or tea-cup, at the age of 3 or 4 months; so that they may not too suddenly, and sensibly, feel the loss of the breast. To facilitate this change, the human milk should be occasionally with-held from them, while the mother or nurse may partake of such aliment as tends to diminish the secretion of that salutary fluid.
Children committed to the care of wet-nurses, ought, in prudence, not to be allowed to suck, after the age of 6 or 8 months; as their infantine faculties then begin to unfold; and they are apt to acquire an undue degree of affection for their foster-mothers. On the other
