traceable to early improvident habits, and of course is the result of irritability and debility of the bladder. There are many patients who can somewhat control the functions of that organ while awake, but have no power over it when asleep. The treatment depends a great deal upon the observance of abstemiousness both in eating and drinking: a perseverance in chalybeate remedies, both taken and administered internally (I have injected the bladder of a person subject to nightly incontinence of urine with various tonic preparations, with very great and permanent relief); the use of the warm bath, whereby the skin is brought into healthier action (for it is generally arid, and parched when much urine is voided), which tends to lessen the duty of the kidneys and urinary system, should be adopted; nor should exercise, that _pabulum vitæ_ of even all feeble persons, be disregarded. It is of the utmost importance for the preservation of health, under all the circumstances in which we may be placed. Escaping from this digression, I now proceed to follow out the idea of the first paragraph of this chapter, to treat of those complaints wherein the urine is voided in excess. There is a disease commonly known by the name of diabetes, wherein the prominent symptom is a continual aptitude to pass urine, and in much greater quantities than the fluid consumed as ordinary drink could supply. This is one form of ailment of this class; but there is another, happily less inimical to life, and which, in the order of its frequency and simplicity, should take precedence. It is that state of health, where the patient is of that leaky habit, that whatever he takes runs through him, and that very quickly too. Of course, such a condition must depend upon a seriously-deranged constitution: hence there is present a perpetual thirst, an entire perversion of the perspiratory function, and a morbid condition of many of the phenomena of life. Where this disease springs up in early years, it becomes a habit proper to existence; and although it may not seriously disturb the economy of the being so as to lessen the duration of one’s stay here, yet it furnishes a source of much solicitude, by depriving us of rest, and shutting us out from society.
