§ 112. Rubeolae.

This exanthem is intermediate between measles an 1 scarlatina, but more allied to the latter: it is even said that the smell which is generally observed about scarlatina patients has been noticed on patients affected with rubeolae. This exanthem generally occurs in an epidemic, but in various forms.

The precursory symptoms are generally of a ca-terrhal-rheumatic nature, but are rarely as strikingly developed as in measles and scarlatina. The throatsymptoms, and particularly the affection of the tonsils, are very violent; the eyes are sometimes red, with lachrymation, sometimes they are dry and itch a good deal. Pressure in the forehead, nausea and vomiting. are likewise present, and are sometimes accompanied by a violent cough; until the eruption breaks out, the skin is dry and hot.

This exanthem attacks principally children and females; it comes out in from 12 to 24 hours, and remains visible for several days. It appears without regular order, first on the face and then on the other parts of the body, or else on the whole body at once. It con-sisis of red spots of one-third of an inch or of a whole inch in circumference, in the centre of which groups of little vesicles become visible, which dry up in five or six days, after which the skin peels off in patches which are larger than in measles and smaller than in scarlatina. The desquamation takes place very rapidly. Dropsical effusions are among the secondary affections of rubeola?.

§ 113. The treatment is pretty much the same as that of scarlatina: Aconite, Be/lad., and Bryonia are among the principal remedies. For the violent angina, Mer-curius is sometimes indicated; and for the excessive thirst and the burning heat of the skin, which make the patients fretful and weak, Arsenic is a real specific.
