Nearly every chemist keeps an “anti-cholera mixture” in a state of preparation, during the cholera season. And as these mixtures are prepared from recipes issued by the Board of Health, or by medical men skilled in the treatment of cholera, they may generally be depended upon. The great thing to be borne in mind is to _take medicines to check looseness of the bowels before the system becomes exhausted_. FEVER. Fever is the result of a diseased or impaired action of the system, and though sometimes attending or following certain diseases as a symptom or consequence, most frequently falls on the constitution as a substantive disease, either developing its characteristic symptoms, as the disease advances, or following the slow maturity of a chain of morbid actions. Fevers may, in the first instance, be divided into those which proceed from some indirect or secondary cause, and those that arise from contagion, or causes the direct precursors of fever, having a definite rise, an understood progress, and a well ascertained termination. In the first named class of fevers, are comprised those febrile symptoms that appear during or after some organic disease, accidents, surgical operations, or other causes of physical suffering. The second, or spontaneous class, is divided into two chief heads—nervous and inflammatory fevers: under nervous fevers are classed typhus, intermittent, continued, and remittent fevers; and under that of inflammatory fevers, first, all eruptive fevers, as scarlet fever, small-pox; and, secondly, the fevers attending all inflammatory actions of organs or viscera, such as inflammation of the liver and bowels. The general characteristics of fever are cold chills, lassitude, headache, loss of appetite, thirst and nausea, with a moist furred tongue, or else a tongue dry and coated, pain in the back and loins, succeeded by cold shiverings, which gradually give place to heat, diffusing itself over the body and becoming permanent; ringing in the ears, intolerance of light, and cold extremities; the pulse is either small and quick, or full and hard. Special fevers, and constitutional temperament, very much magnify, or even mitigate these symptoms; still those given are the ordinary characteristics, and sufficient to indicate the presence of fever to the least accustomed eye.
