Inflammatory fever, as it has often occurred in the GEN. IV. author's own practice, and in that of others who have described it, usually commences with the symptoms of Cauma. an acute ephemera, and may in fact be contemplated as to the same disease running on from four or five to about History of eleven days without intermission or a renewal of the symptoms. cold fit. It commences with a sense of languor and ine aptitude for exertion, with a disrelish for food, which continues for a day or perhaps two. There is then chilliness and soreness over the surface, with nausea and head-ache, succeeded in the evening by a great increase of heat, and at night by perspiration, with great thirst, restlessness, and sometimes delirium: sometimes in young persons, convulsions with a stupid drowsiness. The bowels are usually costive, the urine high coloured, and the pulse quick and hard.

With Dr. Fordyce the grand pathognomic symptom of Pathognocauma is hardness of the pulse. This accompanies it from first to last in its simplest and in its severest state. ness of the

pulse. When the disease is mild, it is hard alone; when more violent, it is at the same time full, strong, and frequent. the pulse The obstructed pulse is often confounded with the hard, and it is not easy to distinguish them without consider- plained. able practice. There is a rigidity of resistance to the finger in each, but of a different kind. In the hard pulse, it is much firmer and tenser; and is supposed by Dr. Fordyce to result from such an increase of arterial contraction as to over-balance its correspondent dilatation. It indicates, in his opinion, a very high degree of living power, and is peculiarly characterized by a tardy coagulation of the blood when drawn freely into an hemispheric bason, in consequence of which the red particles have time to subside, and leave the surface colourless or with a buffy appearance.

ally, a greater spasticity or tetanic resistance in the bloodvessels to the flow of the circulating fluid than in others, whence that acute pain which is often complained of in the head or the side; in the latter case, sometimes amounting to pleuralgia. And, not unfrequently, the vessels of one part will give way more readily than those of another, and there will be a sense of heaviness and oppression in the head, the heart, or the lungs: as though some effusion had taken place, which is perhaps actually the case in some instances. If the head be much affected, delirium is a frequent result, with raving and vio-' lence, rather than the low muttering incoherence of

Whether by by an absorption of bile into the blood-vessels under the a resorption excitement of a tropical sun, or of a torrid summer in of bil milder regions; and they suppose that the bile is, in this case, possessed of a more than ordinary degree of acrimony, and that the symptoms are varied by a more pungent heat and more intolerable thirst, with a more scanty secretion of urine, preternaturally acrid and highcoloured. That bile of this description is often forced back into Inflamma

tory fever the system under the circumstances here supposed, is a frequent unquestionable ; as it is also that inflammatory fever is concomia frequent accompaniment of this morbid change. But, sorbed bile, notwithstanding the above authorities, such fever seems less attributable to the reflux of bile into the blood, than to the insolation or solar excitement; which, by unduly stimulating the liver has been the cause of an overflow of the bilious secretion. How far a more irritant or exalted acrimony may be communicated to bile thus operated upon, or what may be its effect upon the system admitting it to take place, it is difficult to determine; but but perhaps there is much reason to doubt whether genuine bile in the sanguiferous system is ever a cause of fever, or stimulates the heart or arteries to increased action. For if this were the case, jaundice would always be accompanied with inflammatory fever. Instead of which, however, we find it accompanied with atony instead of entony, or diminished instead of increased power.

This is a very common affection in grazing quadrupeds, and especially in sheep, which are often peculiarly tormented, and sometimes driven almost mad by the violence of the irritation.

Stoll gives a case in which the brain, on examination after death, was found deluged with serum-diluvium serosum *. But such an appearance is rather to be regarded as an effect than a cause of the disease; as an instance of cephalitis profunda, in consequence of the brain having suffered more than any other organ from the inflammatory impetus.

There are a few cases, indeed, Cathartics. in which bleeding may be dispensed with, as when the habit is by no means plethoric, and the pulse is obstructed rather than hard; but these are cases that rarely occur. Diaphoretics, or relaxants as they are denominated by Dr. Fordyce, may then be employed with advantage. Of these the tartarized antimony, the antimonial powder, Relaxants. or James's powder, are chiefly to be relied upon; and may be given alone, or, which is often better, in saline draughts; and particularly those formed of the acetate of ammonia. And it may not be amiss to observe here, a

When given as a liquid, it is of importance that the solution should retain the carbonic acid gass of ammonia as largely as possible; and for this purpose the union should take place in a strong close vessel. According to Bergman, nearly half the weight of ammonia depends upon the quantity of this gass which it contains; so that in a pint of the solution of the acetate of ammonia, comprising four drachms of the latter, there will be extricated, if made in the manner here recommended, little less than a hundred and sixty cubic inches of air.
