The community are beginning to appreciate the advantages of temperance, air, and exercise, too highly, to need instructions how much of the one or either of the other two are essential to the preservation or recovery of health. _Morbid Irritability of the Urethra._—Of the varied symptomatic sensations, few are more provoking and fretting than some continued troublesome itching or pain that frequently attends the passing of water. There may be no discharge of any kind, but there is either a constant tingling, partially pleasurable sensation, drawing the attention perpetually to the urethra, or there is felt some particular heat or pain during the act of micturition. These feelings do not always indicate a venereal affection; they appear to depend upon local irritation, perhaps induced by a morbid condition of the urine. The treatment consists in temperate diet, moderatively laxative medicines, and now and then local applications. Some cases yield to sedatives topically applied, and alkalies given internally, while others need local stimulants and specific tonics. At all events, whenever there is an unhealthy feeling in those parts, it points out some altered action is going on, which, if not arrested, is likely to end in stricture or gleet, and therefore attention had better be bestowed upon it as soon as possible. _On Stricture of the Urethra._—Of all diseases of the genito-urinary system, stricture must be allowed to be the most formidable. It is not the most difficult to cure; but it involves, when neglected, more serious disturbances—disturbances which frequently compromise only with loss of life. Stricture is a disease unfortunately of extensive prevalence; and in nine cases out of ten is the sequence of a gonorrhœa; and, what is still more comforting, few persons who become the prey to the latter infliction escape scot-free from the former; not because a clap _must_ necessarily be succeeded by a stricture, but simply because it _is_, and all owing to the carelessness and inattention manifested by most young men in the observances so necessary for the perfect cure of the primary disease. One very prevalent notion, and which explains a principal cause of the extension of the venereal disease, is entertained, that the way to give the finishing _coup_ to an expiring clap, is to repeat the act that gave rise to it: the disease becomes temporarily aggravated, and the impatient invalid probably flies, from an unwillingness to confess his new error, from his own tried medical friend to some professional stranger. From a desire to earn fame as well as profit, the newly consulted prescribes some more powerful means; the discharge is arrested for a while, but returns after the next sexual intercourse; a strong injection subdues the recurrent symptom, which only awaits a fresh excitement for its reappearance. Thus a gleet is established. The patient finding little or no inconvenience from the slight oozing,
