Inflammatory fever manifests itself very suddenly. The animal may appear well during the day, but at night it appears dull, refuses its food, heaves at the flanks, seems uneasy, and sometimes delirious; the pulse is full and bounding; the mouth hot; urine high colored and scanty. Sometimes there are hot and cold stages.
_Remarks._--When disease attacks any particular organ suddenly, or in an acute form, inflammatory fever generally manifests itself. Now, disease may attack the brain, the lungs, kidneys, spleen, bowels, pleura, or peritoneum. Inflammatory fever may be present in each case. Now, it is evident that the fever is not the real enemy to be overcome; it is only a manifestation of disorder, not the cause of it. The skin may be obstructed, thereby retaining excrementitious materials in the system: the reabsorption of the latter produces fever; hence it is obvious that a complete cure can only be effected by the removal of its causes, or, rather, the restoration of the suppressed evacuations, secretions, or excretions.
It is very important that we observe and imitate nature in her method of curing fever, which is, the restoration of the secretions, and, in many cases, by sweat, or by diarrhoea; either of which processes will remove the irritating or offending cause, and promote equilibrium of action throughout the whole animal system. In fulfilling these indications consists the whole art of curing fever.
But says one, "It is a very difficult thing to sweat an ox." Then the remedies should be more perseveringly applied. Warm, relaxing, antispasmodic drinks should be freely allowed, and these should be aided by warmth, moisture, and friction externally; and by injection, if needed. If the ox does not actually sweat under this system of medication, he will throw off a large amount of insensible perspiration.
_Causes._--In addition to the causes already enumerated, are the accumulation of excrementitious and morbific materials in the system. Dr. Eberle says, "A large proportion of the recrementitious elements of perspirable matter must, when the surface is obstructed, remain and mingle with the blood, (unless speedily removed by the vicarious action of some other emunctory,) and necessarily impart to this fluid qualities that are not natural to it. Most assuredly the retention of materials which have become useless to the system, and for whose constant elimination nature has provided so extensive a series of emunctories as the cutaneous exhalents, cannot be long tolerated by the animal economy with entire impunity."
