to Night-Mare, should be perceived, there will be just reason to apprehend that it will occur, and it will be advisable to have recourse to some preventative. The paroxysm of Night-Mare does not always immediately follow the eating any improper food, b℥ut sometimes several days elapse before its attack. In this case it is easier to foresee, and consequently to prevent it. The signs by which its approach may be known, are unusual drowsiness, disagreeable dreams, and disturbed sleep, with wind in the stomach and bowels. In this case I would recommend immediate recourse to be had to the carbonate of soda, as I have described above, or to the following draught, which may be taken at bedtime. No. 1. ℞. _Potassæ Carbonatis._ gr. x. _Tinct. Cardam. Comp._ f. Ʒ iij. _Syrupi Simplicis._ f. Ʒ j. _Aquæ Menth. Pip._ f. ℥ j. _M. fiat haustus._ Or this, No. 2. ℞. _Ammon. pp._ gr. x. _Tinct. Capsici._ f. Ʒ j. _Syr. Croci._ f. Ʒ j. _Aqua Cinnamom._ f. Ʒ x. _M. fiat haustus._ Should these medicines not produce any relaxation of the bowels, it would be necessary to take next morning a dose of some of the neutral purging salts, or, what will answer equally well, the following aperient draught. No. 3. ℞. _Magnesiæ._ _Pulv. Rhabarb._ a. gr. xv. _Potassæ Carbonat._ gr. viij. _Syr. Simpl._ f. Ʒ j. _Aquæ Menth. Pip._ f. Ʒ xj. _M. fiat haustus._ To those persons however, who are habitually subject to Night-Mare, I would advise the frequent repetition of one or other of the draughts, No. 1 or No. 2, for several nights in succession, after which the aperient draught, No. 3, may be taken, if necessary. And this plan I would recommend to be adopted whenever the symptoms of predisposition mentioned above are perceived, paying great attention at the same time to regularity and choice of diet. Intemperance of every kind is hurtful, but nothing is more productive of this disease than drinking of bad wine. Of eatables, those which are most prejudicial, are all fat and greasy meats, most vegetables, fruit, and pastry. These ought to be avoided, or eaten with caution. The same thing may be said of salted meats, for which dyspeptic patients have frequently a remarkable predilection, but which are not, on that account, the less noxious. Moderate exercise contributes in a superior degree to promote the digestion of food, and prevent the formation of flatulence: to those however who are necessarily confined to a sedentary employment, I would recommend particularly to avoid applying to study, or any other sedentary occupation immediately after eating. If a strong propensity to sleep should occur after dinner, it will be certainly better to indulge it a little, as the process of digestion frequently goes on much better asleep than awake. I have always felt at sea an irresistible propensity to sleep after dinner, whenever the dyspeptic
