Enlarged Tonsils.—I have said that quinsey or acute inflammation of the tonsils is unusual in early childhood; but a sort of chronic inflammation of those glands which leads to their very considerable enlargement is far from uncommon; and is sometimes the cause of very serious discomfort. It is seldom traceable to any acute attack of sore-throat, but usually comes on imperceptibly in children who are feeble or out of health, or takes place slowly during the cutting of the first set of grinding teeth; the irritation which that produces being in some cases its only apparent exciting cause. Not seldom the enlargement has become considerable before it attracts attention; one of the first symptoms that indicate it being the loud snoring of the child during sleep, who is compelled by the obstruction at the back of the nostrils to breathe with its mouth open. The voice at the same time becomes thick, and this and the snoring breathing are both greatly aggravated when the child catches cold.

A greater degree of enlargement of the tonsils occasions deafness from pressure on the passage leading to the internal ear, and is also apt to give rise to a troublesome hacking cough which sometimes excites apprehension lest the child's lungs should be diseased. When still more considerable the enlarged tonsils block up the passage through the nostrils, and air consequently enters the lungs but very imperfectly. The nostrils thus disused become extremely small, narrow, and compressed, the upper jaw does not undergo its proper development, the teeth are crowded and overlap each other, the palate remains narrow and unusually high-arched, and the face assumes something of a bird-like character. Besides this the child grows pigeon-breasted, owing to the lungs not being filled sufficiently at each inspiration to overcome the pressure of the external air on the yielding sides of the chest.

When any considerable enlargement of the tonsils exists, each cold that the child may catch aggravates it, and if diphtheria, scarlatina, or severe sore-throat should occur, the temporary increase of the swelling may become the occasion of serious danger. The question arises, what are the chances that a child whose tonsils are enlarged will outgrow the condition, or when is it necessary to have the enlarged tonsils removed?

It scarcely ever happens that any such enlargement of the tonsils exists in children under six years of age as to call for their removal. There is almost always ground for the hope that after the irritation caused by cutting the first four permanent grinding teeth has completely ceased, the tonsils may return by degrees to their former size. A similar shrinking of the enlarged tonsil sometimes takes place, especially in the boy, at the time of approach to manhood, when the vocal organs undergo full development. This can be counted on, however, only in cases where the tonsils are not of extreme size, and have not undergone frequent attacks of inflammation. Whenever the hearing is habitually dull, and the voice always thick, when cough is frequent, the nostrils narrow, the chest pigeon-breasted, and the child feeble and ill-thriven, removal of the tonsils is absolutely necessary. In cases where the question is doubtful, its decision must turn on whether the tonsils have often been inflamed. So long as their surface is smooth, and their substance soft and elastic, delay is permissible. When their substance is hard, like gristle, and their surface uneven and corrugated, they have undergone such changes that absorption is impossible, and their removal absolutely necessary.

I dwell thus particularly on the question of removal of the tonsils, because there is among many persons an unreasoning dread of the operation, which is entirely devoid of danger, requiring only a few seconds for its performance, and which may even be done under chloroform. The painting tincture of iodine behind the angle of the jaw, or the touching the tonsils with caustic, iodine, alum, tannin, or sweet spirits of nitre are utterly futile proceedings. They diminish the unhealthy and often offensive secretion from the glands which beset the tonsils, and restore the surface to a more healthy condition, but they are absolutely without influence in lessening their size.

Now and then all the symptoms of enlarged tonsils are present, but yet most careful examination fails to discover any increase of their size. When this is the case the symptoms are due to a thickening of the membrane at the back part of the nostrils, often attended with spongy outgrowths from their surface, which obstruct just as completely as enlarged tonsils would do the free entrance of air. It will, in any case where this condition is suspected, be absolutely necessary to seek the advice of some of those gentlemen who make a specialty of diseases of the throat, and who will have the necessary technical dexterity to discover the condition, and to treat it skilfully.

Abscess at back of the Throat.—I should pass unnoticed, on account of its rarity, the occasional formation of an abscess at the back of the throat, behind the gullet, interfering both with breathing and with swallowing, but that the description of it in my Lectures once enabled a lady in the wilds of Russia to detect it, to point out the nature of the case to her puzzled doctor, to urge him to open the abscess, and thus to save her child's life.

This abscess may form at any age, sometimes after fever, sometimes without any obvious cause. It shows itself by difficulty in swallowing and breathing, unattended by cough, but accompanied by a sound similar to that of croup, but not so harsh or ringing. The neck is stiff, the head thrown back, and often there is a distinct swelling on one or other side of the neck. The finger introduced into the mouth, and carried over the tongue to the back of the throat, feels there a swelling which projects over the top of the windpipe, and causes the difficulty both in swallowing and breathing. This swelling is the abscess; a prick with the surgeon's lancet lets out the matter, and saves the child.

Diseases of the Kidneys.—The kidneys perform very important duties in carrying off from the system a large amount of useless material, and thus supplement in many respects the action of the skin, and the purifying influence which is exercised by the air on the blood, as it passes through the lungs.

It is evident, therefore, that their disorder in any way must be a matter of serious moment, though at the same time the knowledge of the skilled doctor is needed to determine the nature and degree of the ailment from which they are suffering, since that requires an examination of the urine, both chemically and by means of the microscope. My remarks on these diseases must consequently be few and fragmentary.
