Youth, or rather the approach of adultism, is the favorite season of the attack, which is most prevalent during the spring time of the year. There is, however, no period or any age which are altogether exempt from its influence. All kinds of treatment have been experimented with. Bleeding, purging, blistering, setoning have all been tried, and each has destroyed more lives than the whole can boast of having saved; experience has by slow degrees shown the inutility of active treatment. _Bold_ measures, as those plans are termed which add to another's suffering, commonly end in hydrothorax or water on the chest. It is difficult to determine when the first symptom of influenza is present. The author is indebted to the acuteness of Mr. T. W. Gowing, V. S., of Camden Town, for a knowledge of a marked indication declarative of the presence of influenza. A yellowness of the mucous membranes, best shown on the conjunctiva or white of the eye, is very characteristic. Whenever the sign is seen and sudden weakness remarked, caution should be practiced, for it is ten to one that the pestilence is approaching. Influenza is a very simulative disorder; it has appeared as laminitis; disease of the lungs is, perhaps, its favorite type. Bowel complaints are apt to imitate each other; blowing generally commences such disorders. But when influenza is prevalent, let the body's strength and the yellowness or redness of the membranes be always looked to before any more prominent indication is particularly observed. The other symptoms--which, however, are very uncertain, as regards any of them being present or absent--are pendulous head, short breath, inflamed membranes, swollen lips, dry mouth, enlarged eyelids, copious tears, sore throat, tucked up flanks, compressed tail, filled legs, big joints, lameness and hot feet. Auscultation may detect a grating sound at the chest, or a noise like brickbats falling down stairs at the windpipe; whenever this last peculiarity is audible there is a copious nasal discharge. Sometimes one foot is acutely painful, and, notwithstanding the weakness, the leg is held in the air. Purgation has been witnessed, although constipation usually prevails, and the animal generally stands during the continuance of the disorder. [Illustration: CONFIRMED INFLUENZA.]
