thing that vitiates the air, and thus depresses the system, more especially if the weather be close and muggy; poor and improper food; and last, though not least, contagion. Bear in mind, too, that delicate children are much more predisposed to it than the strong.

165. Have the goodness to describe the symptoms of Measles?

Measles commence with symptoms of a common cold; the patient is first chilly, then hot and feverish, has a running at the nose, sneezing, watering and redness of the eyes, headache, drowsiness, a hoarse and peculiar ringing cough, which nurses call "measle-cough," and difficulty of breathing. These symptoms usually last three days before the eruption appears; on the fourth, it (the eruption) generally makes its appearance, and continues for four days, and then disappears, lasting in all seven days from the commencement of symptoms of cold to the decline of the eruption. It is important to bear in mind, that the eruption consists of crescent-shaped patches; that they usually appear first about the face and neck, in which places they are the best marked; then, on the body and arms, and, lastly, on the legs; and, that they are slightly raised above the surface of the skin. Well then, bear in mind, the running at the nose, sneezing, the peculiar hoarse-cough, and the crescent-shaped patches, are the leading features of the disease, and point out, for a certainty, that it is measles.

166. What constitutes the principal danger in Measles?

The affection of the chest. The mucous membrane of the bronchial tubes is always more or less inflamed; the lungs themselves are oftentimes affected; on which account, it is highly necessary, that the Medical man should be sent for at the very commencement of the disease, that he may watch its progress, and combat the inflammation the moment it arises.

167. Do you recommend" surfeit-water" and saffrontea to throw out the eruption in Measles?

Certainly not. The only way to throw out the eruption (as it is called) is to keep the body comfortably warm, and to give the beverages (ordered by the Medical man) with the chill off. "Surfeit-water," saffron-tea, and remedies of that class, are hot and stimulating. The only effect they can have, will be, to increase the fever and inflammation-to add fuel to the fire.

168. What is the difference between Scarlatina and Scarlet-fever?

They are, indeed, one and the same disease, "scarlatina" being the Latin for scarlet-fever. But in a popular sense, when the disease is mild, it is usually called scarlatina. The latter term does not sound so formidable to parents' and patients' ears.

169. Please to describe the symptoms of Scarletfever?

The patient is generally chilly, languid, drowsy, feverish, and poorly for two days before the eruption

appears. At the end of the second day, the characteristic bright-scarlet efflorescence (somewhat similar to the colour of a boiled lobster) usually first shows itself. The scarlet appearance is not confined to the skin; but the tongue, throat, and whites of the eyes put on the same appearance; with this only difference, that on the tongue and throat the scarlet is much darker; and, as Dr. Elliotson accurately describes it, "the tongue looks as if it had been slightly sprinkled with Cayenne-pepper." The eruption usually declines on the fifth, and is generally indistinct on the sixth day; on the seventh, it has completely faded away. After the first few days, there is usually great itching of the surface of the body. At the end of the week, the skin begins to peel and dust off, making it look as though meal had been sprinkled upon it. There are three forms of scarlet-fever; the one where the throat is little, if at all, affected, and which is a mild form of the disease: the second, which is generally attended with delirium, especially at night, where the throat is much affected, being often greatly inflamed and ulcerated; and the third, (which is comparatively rare and very dangerous) the malignant form.

170. Would it be well to give a little cooling openingphysic as soon as a child begin to sicken for Scarletfever?

On no account. Aperient-medicines are, in my opinion, highly improper and dangerous both before and during the period of the eruption. It is my firm conviction, that the administration of opening-medi

cine, at such times, is one of the principal causes of scarlet-fever being so fatal. Of course, this is more applicable to the poor, and to those who are unable to procure medical assistance.

171. What constitutes the principal danger in Scarlet-fever?

The affection of the throat, the administration of opening-medicine during the first ten days, and a peculiar disease of the kidneys ending in anasarca (dropsy); on which account, the Medical man should be sent for at the onset, that no time may be lost in applying proper remedies.

172. How would you distinguish between Scarletfever and Measles?

Measles commences with symptoms of a common cold; scarlet-fever does not. Measles has a peculiar hoarse cough; scarlet-fever has not. The eruption of measles is in patches of a semi-lunar shape, and is slightly raised above the skin; the eruption of scarletfever is one continued mass. The colour of the eruption is much more vivid in scarlet-fever than in measles. The chest is the part principally affected in measles, and the throat in scarlet-fever.

173. Is it of so much importance, then, to distinguish between Scarlet-fever and Measles?

It is of great importance, as, in measles, the patient. should be kept moderately warm, and the drinks should be given with the chill off; while, in scarlet-fever the patient should be kept cool, indeed, for the first few days, cold, and the beverages, such as spring-water,

toast-and-water, barley-water, etc.-should be administered quite cold. Moreover, in scarlet-fever, a Medical man sometimes considers it necessary to sponge the body with cold vinegar and water; if the case were measles, such sponging would be fraught with great danger.

174. How soon should a child be allowed to leave the house after an attack of Scarlet-fever?

He should not be allowed to go out for at least a month, from the commencement of the attack, in the summer, and six weeks in the winter, and not even then, without the express permission of the Medical attendant. It may be said, that this is an unreasonable recommendation; but when it is considered, that the whole of the skin generally desquamates or peels off, and consequently leaves the surface of the body exposed to cold: which cold flies to the kidneys, producing a peculiar and serious disease of them, ending in dropsy-this warning will not be deemed unreasonable. The talented and accomplished Dr. Watson thus accurately describes anasarca following an attack of scarlet-fever." But certainly the most common, and a very serious sequel of scarlatina, is anasarca, serous infiltration of the subcutaneous areolar tissue, accompanied often with dropsy of the larger serous cavities. So common is this, that Cullen has even introduced the circumstance as a part of his definition of scarlet-fever. He found the dropsy a very manageable complaint; but it really is, in many-nay, in most cases, if we look to its probable ultimate consequences-a most formidable
