In continued fevers emetics are highly useful, but their effects are not equally striking. The debilitating power of every febrile attack affects the stomach, and produces those irregularities of the digestive process which we have already described. The wholesome aliment is, in this way, converted into an injurious load; and emetics are not more useful in determining to the skin, than in removing the acrimonious or putrid saburrae. When contagion also has been received, though breathed with the air, it immediately affects the stomach, producing a bad taste in the mouth. This, with all the subsequent bad consequences, an emetic, followed by a brisk cathartic, will often remove. The particular kinds of fever offer few remarks of importance. In the synocha, bleeding, if it be at all admissible, should be premised; but the young practitioner, eager with his lancet, should reflect, that every throbbing pulse is not a strong one; nor does every headach portend approaching delirium. Emetics have often been of service even in the most inflammatory fevers, when bleeding has not preceded; and we should always consider, that the most putrid fevers are sometimes ushered in by symptoms seemingly inflammatory. In the lower putrid fevers, emetics are useful; but the nauseating doses, which may be continued in inflammatory fever, should soon be omitted in the latter, as they debilitate in a considerable degree.

In the next order, the phlegmasiae, emetics are less essentially necessary; and, in these, bleeding must be frequently premised. After vomiting, the nauseating doses may be continued with the best effects. In the pneumonia they are often important remedies, from their power of emulging the bronchial glands. In phrenitis, though dangerous from increasing the accumulation in the head, we are sometimes obliged to employ them. In cynanche they are inconvenient, though useful, remedies. When the inflammation terminates in suppuration, suffocation often impends, and then vomiting, a precarious remedy, which may even bring on the fate it is intended to avert, may at once rescue the victim from the grave. Firm and steady must be the physician who prescribes it; but he who would for a moment hesitate when his patient's life is at stake, whatever risk he may personally run, merits not the name of man, nor the character of a physician. In the other pyrexiae we find little room for the use of this remedy. In hepatitis, for obvious reasons, it is doubtful, -though sometimes useful; in enteritis the natural vomiting is often the most troublesome symptom; but in the peritonitis pu-trperarum, emetics, given early, have been considered as a most certain remedy. It would give us the greatest satisfaction could we confirm these assertions. On trial we have, however, found them useful. In gout, emetics have been employed to obviate the return of paroxysms; and in rheumatism, if bark be useful in this view, vomits must be equally so.

If the explanation we have offered of febrile cutaneous diseases be correct, emetics must be a remedy of peculiar value and importance in the order exanthemata. We need not enlarge on the different kinds, for in each these remedies are useful on the first appearance of fever. In those, however, attended with nervous or putrid fever, the repetition must be attempted with caution.

In hemorrhages, emetics are supposed of doubtful efficacy; but they are more generally useful than has been supposed. With respect to the haemorrhagia cerebri we shall reserve our observations for the present; and in epistaxis we need not have recourse to an active, uncertain remedy, when we have more safe ones within our reach. In hemoptysis, emetics have been forbidden; but with little reason. Dr. Robinson, near sixty years since, recommended them as safe and effectual remedies; and we know that there are none which more certainly deserve this character: yet the general opinion is so decidedly in opposition to their employment, that, unless in emergency, we think they should not be exhibited; or even in emergency not professedly as emetics. One of the most obstinate haemop-tyses the author of this article ever saw, yielded only to the digitalis, which acted as a violent emetic; and its action was continued for several days. The bleeding only ceased during the operation of vomiting, and was finally stopped. Vomiting has been employed with success in maenorrhagia; but a physician may brave popular prejudice more safely in any disease than in female ones: nor is their utility in this complaint very clearly established. We speak, however, only at present of febrile maenorrhagia.. In every other kind, emetics are decidedly injurious. Of the proflavia, the only genera, catarrh, and dysentery, are greatly benefited by these remedies; nor can we add to what we have already remarked respecting their utility, or offer any observations to limit their employment.

The order neuroses offers abundant subject of discussion, was this a place for extensive inquiries; and had we not, in part, anticipated every essential remark. It will be at once obvious, that we refer to apoplexy and palsy, and the disputes which have arisen on the subject. In our former article (see Apoplexia) we gave the result of our observations; and then remarked that, though we had been ourselves cautious in the exhibition of emetics, we had seen them employed by others without injury; adding, that their inconveniences were slight and transitory, their good effects considerable and permanent. To this we may now subjoin what has since occurred in the progress of our work, that the venous system of the brain is apparently calculated to admit of distention, without any essential injury. The coats of many of the sinuses, particularly those at the base of the brain, admit easily of distention, are tortuous, and anastomose freely. On the whole, then, though we must consider emetics as remedies somewhat precarious, we think that they ought to be employed in such circumstances; and on taxing, most impartially, our recollection, we cannot find that, in a single instance, in our hands, or those of others, they have been hurtful. On the contrary, we have very often found them beneficial.
