known to any one who has witnessed an attack of the croup; it rings as if the child had coughed through a brazen trumpet; it is truly a tussis clangosa; it penetrates the walls and floor of the apartment, and startles the experienced mother,'Oh! I am afraid our child is taking the croup!' She runs to the nursery, finds her child sleeping softly, and hopes she may be mistaken. But remaining to tend him, before long the ringing cough, a single cough, is repeated again and again ; the patient is roused, and then a new symptom is remarked; the sound of his voice is changed; puling, and as if the throat were swelled, it corresponds with the cough," &c.

How important that a mother should be acquainted with the above signs of one of the most terrific complaints to which childhood is subject; for, if she only send for medical assistance during its first stage, the treatment, if vigorous and judicious, will be almost invariably successful ; whereas, if this "golden opportunity" is lost, this disease will seldom yield to the influence of measures, however wisely chosen or perseveringly employed.

-OTHER CIRCUMSTANCES WHICH WILL ASSIST

IN THE EARLY DETECTION OF DISEASE.

1. The influence of the seasons in producing particular forms of disorder. The recollection of the fact, that at the different seasons of the year some diseases are more prevalent than at other periods, will greatly aid a judicious parent in the early detection of the presence of disorder, and its kind, in her child.

Thus, in the early part of the winter, what is called catarrh, viz. an increased secretion of mucus from the membranes of the nose, fauces, and airtubes, with fever, and attended with sneezing and cough, thirst, lassitude, and want of appetite, is generally prevalent.

As the winter advances, the air-tubes of the lungs, and the lungs themselves, are liable to become the seat of disorder; and those signs will present themselves, which have been pointed out in the previous section as characteristic of such attacks.

In the spring, we have still the same diseases. prevalent, and in addition, measles, scarlet fever, small-pox, and chicken pox, which increase in liability towards the close of this season, and with the first weeks of summer.

In the summer, disease is less prevalent than at

any other period of the year; but towards its middle and close, and through the whole of the autumnal months, bowel complaints may be expected, in the forms of diarrhoea, cholera, and dysentery.

2. The influence of an hereditary predisposition to certain diseases. Without entering into this subject at large, still it may be useful to remark, that in some families there is a predisposition to some diseases, which, occurring in the first child, will, as each succeeding child is born, attack at the same age. Amongst other diseases of this class are, croup, hooping-cough, and water in the head.

This observation should not only lead a mother to be alive to the possibility of the successional occurrence of these diseases in her family, and so early note their appearance, and seek medical advice, but should at the same time make her most anxious, on the one hand, to shield her child from all their exciting causes, and on the other, to adopt those measures which may contribute indirectly to overcome the constitutional predisposition to them.

Of the scrofulous constitution, I will merely mention here, that it is of the greatest importance, where a predisposition to this disease exists in a

family, that a mother should immediately attend to any alteration in the gait or contour of her child, and give prompt attention also to any complaint made of swelling about a joint, although it may be unattended with pain. The importance of this remark will be seen by contrasting the result of the following cases which occurred in children of the same family.

CASE I.

A. B., a female child, having blue eyes, light hair, and a fair complexion, in the early part of the year 1838, being then two years of age, had an enlargement of the left knee joint. For some weeks previous to this time, there had been a degree of heat about the part; but as no pain apparently existed, it was not regarded as of any consequence, and nothing was done. The child living in the neighbourhood of London, was afterwards placed under medical treatment. Two or three months having elapsed, it was brought to town, and shown to me, in consequence of a slight tumefaction over the lower part of the spine. This soon disappeared under the measures employed, and eventually the disease of the knee (evidently scrofulous) was arrested, so that now the case promises to be cured; but the joint will for ever be stiff, and the limb thus affected shorter than the other.

CASE II.

G. B., the brother of the above, a handsome boy, with light hair, fine blue eyes, — indeed, very much like his little sister,—in the year 1836, had enlargements of the glands in his neck, which were relieved by the treatment resorted to.

In April, 1839, being then eight years old, he was observed by his mother to limp slightly in walking, but complained of little or no pain. From the caution, however, which had been given to the parent at the time I was consulted about the previous case, to "notice at an early period any symptom of this nature in her children, the fact was immediately attended to. The affection was evidently in the hip; there was imperfection in the gait, and pain upon pressing over the joint. A blister was applied, perfect rest to the limb enjoined, and steel medicines ordered; and in a fortnight the motions of the joint were restrained more effectually by the application of strips of soap plaster and a bandage. In three months the child was ordered to the sea-side, and eventually was able to walk without the slightest limp or pain, and may be said to be quite well.

I would not say that in the first case, if the disease had been discovered early, and at that time
