ber of suckers, speedily thicken, and furnish a fine coppice.
The kernels of the fruit of the hazel-nut tree, though difficult of digestion, have a mild, farinaceous, oily taste, which is agreeable to most palates; yet filberts are said to be more nourishing than nuts: both, however, operate as a cathartic, when chewed small and taken in considerable quantities; but produce constipations of the bowels, if swallowed in large pieces; and dysentery, if eaten unripe. A kind of chocolate has been prepared from this fruit, which has also occasionally been converted into bread. An expressed oil is obtained from the nuts, which is little inferior to that of almonds: it is often preferably used by painters, as it readily dries; and chemists employ it as the basis of fragrant oils artificially prepared, because it easily combines with, and retains, odours. An emulsion made of the kernels, and taken with good old mead, is recommended for inveterate dry coughs.—Squirrels and mice are excessively fond of the nuts; goats and horses eat the leaves, but they are refused by sheep and hogs.
HEAD, the uppermost or foremost part of the animal body.
As the foundation of many diseases is laid, by taking cold in this part of the frame, we shall offer a few hints relative to its covering.—For new-born children, an easy and moderately warm head-dress is fully sufficient during the first weeks of their existence; as superfluous ornaments only tend to encumber and to fatigue them. The infant's cap, however, ought not to be narrow, nor tied too closely, lest the head be compressed, the muscles of the ears crippled, and the sense of hearing impaired.
It is equally hurtful for children and adults to walk in the sun with the head uncovered, yet our cumbersome black hats though sanctioned by custom and fashion, are generally too heavy for the hot days of summer; they ought to be manufactured of lighter materials, and either white, or dyed of some light colour, especially for soldiers, travellers, and persons labouring in the field. Such individuals should wear hats made of oil-cloth, supported by fine wires, or of straw, chips, &c.
In this temperate climate, youth may with safety be accustomed to go with their heads uncovered; but, in those countries where either of the two extremes of heat or cold prevail, the opposite practice must be adopted.
Many diseases, however, might be avoided, were the trite, but true maxim of "keeping the head cool," more strictly attended to. Hence the wearing of thick and warm night-caps, whether at night, or in the day time, cannot be too much reprobated; as those who indulge in this whimsical habit, render themselves continually liable to take cold from the slightest change in the atmosphere: thus baldness, violent head-achs, and not unfrequently a lethargic stupor, or insanity, are among the many fatal effects which sooner or later follow this imprudent custom.—See also Hair.
HEAD-ACH, or Cephalalgia, a painful sensation in the head, produced by various causes, and attended with different effects, according to its various degrees, and the part of the head where it is situated.
