And lastly, to add a few to the number of those already presented herein, of the infirmities of those organs which excrete the fluid under consideration, namely, the kidneys and bladder. ON INCONTINENCE OF URINE. ALTHOUGH this is not the professional term for the disease I am principally about to speak of, yet under this head will the reader, if he be an invalid laboring under a complaint of this character, seek for a description of his own case. Incontinence of urine implies a loss of the retentive faculty of the bladder; but there is a species of disease where micturition is carried to such an extent, that a patient will attribute his leaky condition to the above cause. Not so, however, is the case; the urine, in the disease alluded to, is generated or excreted in great quantity, and the bladder merely fulfils its ordinary duty. Of the affection known under the title of incontinence of urine, most persons are aware that it is one of more frequent occurrence in infancy than in adolescence; but the latter is by no means exempt. In childhood it arises, in all probability, from drinking too much, and the bladder becomes, during sleep, overloaded, and runs over; or, perhaps, from the irritability induced by its distension, becomes excited to action, and so empties itself, the drowsy state of the child rendering it insensible to the passing circumstances. The infirmity soon becomes a habit, which is often rendered worse by the means taken to check it, namely, chastisement, which is highly reprehensible. It is fortunately, however, a disease that wears itself out as the child grows up; and it may at all times be materially mitigated by a little care and attention, such as inducing the child to micturate before going to bed, and even awakening it before the anticipated time when it usually is attacked with the incontinence. The last fluid meal, which should be a spare one, should be taken some hours before retiring to rest; and if the complaint has gained much ascendency, medicines which give tone to the bladder should be taken. I have known the malady successfully removed, in a very short time, by a combination of the sulphate of iron and quinine, and any sedative extract, such as henbane or hops, given in small doses in the form of pills. Female children are more susceptible of the annoyance than males, probably owing to the shortness of the urethra. Every measure tending to give strength to the child should be used, such as cold bathing, fresh air, or a change of the same, especially if residing in the city, to the country. Mechanical contrivances are to be had to collect the escape of urine, whereby the offensive odor arising from the continually soiled bed-linen may be avoided, and oftentimes the fretting consequences of the urine passing over the person, which induce excoriations and troublesome sores. There are contrivances for both sexes. Where the disease prevails in mid-life, it is generally
