Sedlitz, or Seydschutz-Water, is obtained from two mineral springs rising near a village of that name, in Bohemia. It has a very saline, bitter taste ; and when used, is strongly laxative, but does not occasion the griping pains attendant on other violent purgatives.

The principal complaints which Sedlitz-water is calculated to lieve, are by HoFF man stated to be, 1. All cases of indigestion, accompanied by nausea, aversion to. or loathing of, food, and a painful compression of the chest; 2. Hypochondriasis, in which it is preferable to the aloetic and other strong purgatives ; 3. Suppressions of the natural discharges; 4.The impaired state of health to which sedentary persons are peculiarly liable; 5. The tendency to hemorrhages in persons of a plethoric habit; and, 6. Obstinate cutaneous affections. - The dose varies according to the age and constitution of the patient: in general, from half a pint to a pint is sufficient; though some persons are obliged to drink two pints, in order to produce the desired effects.

Seed is the embryo contained in the fruit of vegetables; or, according to Linnaeus, a deciduous part of a plant, comprising the rudiments of a new terraqueous production.

As all the various vegetables, fruits, etc. used in rural and domestic economy, are raised from seeds, the most eminent naturalists have bestowed particular attention on the subject of selecting, preserving, and sowing them. - We shall therefore concisely state the result of the most successful experiments, under these respective heads.

I. The Selection of seeds depends principally on a proper choice of grains and kernels, as well as roots from the most vigorous vegetables, growing under our own inspection : for, though it be conjectured, that the constant cultivation of a particular plant from the same seed, and on the same soil, will at length cause it to degenerate, yet numerous well-attested instances have occurred, in which the contrary effects have been evident. The most healthy stalks or stems should, therefore, be selected for bearing seeds; and such as attain to maturity at the earliest period in the season, ought to be preferred, especially if they grow at a distance from weakly plants of the same species ; lest the fecundating farina of the latter be blown upon the stigmata of the former, and an inferior kind, or succession, be produced.

The proper time for gathering seeds, is the period of their perfect maturity, which may be ascertained by the dryness of the stem ; because, when the latter begins to decay, it becomes "bleached by the oxygen of the atmosphere, " and no farther nourishment can then be conveyed to the ripe seed. The harvest should now be commenced without delay; and numerous hands be employed in threshing and housing it, lest any shower should fall, and thus a considerable portion be scattered on the ground.

II. Various expedients have been devised, for the preservation of seeds : the most simple consists in secluding them from light and heat in the bowels of the earth ; where they will retain their vegetative power for several years. Thus, Dr. Darwin mentions instances of mustard-seed producing a crop, on digging up soil, where it had remained in a state of rest for many years, and, " as was believed, even for ages." In the same manner, the best cucumbers and melons are raised from seeds, which are at least three or four years old ; though some gardeners do not employ them, till they have been kept ten or twelve years.

Where seeds of a perishable nature are to be carried to, or brought from, distant places, it has been found useful to cover them with a thin coating of a mixture of pitch, resin, and bees-wax ; which composition is termed mummy. Acorns and other seeds, thus managed, have appeared, on importation, as fresh as if they had been newly gathered. - Dr. Darwin conjectures, that they might be safely preserved by covering them with soft sugar; and his supposition has been confirmed by the experiment of Mr. Sneyde (recorded in the 16th volume of the " Transactions of the Society for the Encourage-ment of Arts" etc), who observed, that such as were packed in sugar, or among raisins, not only appeared healthy, but grew readily, while many others would not ve getate.

treating of the respective v bles, in the order of the alphabet, here only mention the opinion of Dr. Darwin, that the most ntageous method of disseminating- native plants; is by suffer-n to drop on the surface, of the soil, as they fall from the parent covered only by their deciduous leaves. But, when these germs of vegetation are imported from distant climates, such as will ripen in the same year, ought to be sown at an early pe in the spring, and slightly covered with mould, in order to shelter m bird is, on the contrary, w not comple .;ate in one r, should be committed to the ground in the beginning of autumn, at the depth of an inch and a half; both, for protecting them from the frost, and from the depredations of birds. As: precautions, however, are tin prehave recommended the steeping of valuable seeds in a strong solution of the liver of sulphur, for thr four or such time as will be sufficient to penetrate the skin, or husk c by this simple expedient, all vermin will be effectually prevented from devouring the seed.
