From such an arrangement of the materia medica, and this subdivision of the classes, the young student, or the more discriminating inquirer, will, we think, find his labour greatly facilitated, as he will not be obliged to range through a muster roll of names to attain the object of his search. It remains only to explain the foundation of these subdivisions.

Emetics, though a class far from numerous, and of simple operation, yet require some distinctions. We do not always require full vomiting, and we sometimes want this action to produce a very sudden and violent change. It may be supposed that all emetics, in a less dose, will nauseate, or in a more active one give a sudden and violent shock; but ipecacuanha seldom produces sickness without vomiting, and squills will very seldom occasion a complete action of the stomach. Ipecacuanha also acts with no more violence in a large than a small dose, and mercurius vitriolatus is severe in its operation even in a small one.

Of cathartics and the foundation of the distinctions we have already spoken; and these lead us to remark another advantage of the subdivisions, a more ready reference to the proper remedies in other parts of the catalogue. Drastic purgatives would be injurious as diuretics in nephritis, and mild ones very inefficient as anthelmintics.

There is certainly a very striking, and, in a practical view, a very important, distinction between the relaxant and the stimulant -diaphoretics. If we have been right in our views under this article, the diapnoica equally merit a selection. A view of the remedies included in the list will, at least, show the propriety of the distinction. It appeared, indeed, so strong, that in the first sketch of this article, made for a very different purpose, twenty-five years since, the alterantia were included in this class.

The stimulant, the diluent, and the narcotic diuretics are equally distinguishable. Perhaps the salina are not properly arranged with the stimulantia; but we were determined by the fact, that nitre, and some of the other neutrals, in large doses, produce pain in making water. They are, however, distinguished; the strontia and ba-rytes are inserted with doubt and hesitation.

The division of the extensive and doubtful class of expectorants is made from the nature of the medicines recommended. The first, however, act chiefly on the fauces; the second and third on the fever, except where employed in the form of gas or vesicular vapour. The fourth contains only the real expectorants; and of the whole subdivision there are few strictly such. Some of these are slightly astringent, and should have been separated to have marked them as frequently injurious, or at least only useful in a relaxed state of the glands. Of these the agrimony marked with a note of interrogation is the most hurtful; but the whole of the group must be used with caution when inflammation exists.

Dr. Cullen used to distinguish the errhines according to their effects as irritants and evacuants; but we found it difficult to follow the idea on an extensive scale; and the whole, at last, seemed resolvable into their less or greater acrimony. At least this distinction is abundantly sufficient to assist our practice.
