GENERAL DISEASES. 95 



neck, body, and extremities, smooth blotches, over which the 

 hair is elevated, though the skin itself is little or not at all 

 elevated. 



The second form of rash consists in the eruption in vari- 

 ous parts of the body, especially on the inner aspect of the 

 thighs, of small rounded vesicles, which eventually desic- 

 cate. 



The nasal mucous membrane and the membrane of the 

 mouth are covered with scarlet spots, or petechise, of variable 

 size. These spots are especially seen on the nasal septum, 

 and on the inner surface of the lips. From the nose there 

 is a serous discharge which gradually becomes yellowish- 

 brown in colour. 



The limbs are generally swollen, and the animal is stiff. 

 In some cases of scarlatina there is no eruption, and minute 

 spots on the Schneiderian membrane are all we have to 

 guide us in the diagnosis. 



Soreness of the throat is present in most cases. 



Symptoms of Scarlatina Anginosa. — Scarlatina anginosa 

 is a severe form of the disease^ in which the throat and 

 upper air-passages are especially involved. The symptoms 

 may at first be those of the simple form, and then gradually 

 increase in severity ; or the fever may assume a severe form 

 at the outset. In this form the limbs swell rapidly. 



The swellings are hot and painful, and may also appear 

 on the face and head. 



The rash and vesicular eruption are more frequently found 

 on the limbs than the body, and appear as in the simple form, 

 in successive crops, or spread by the coalescence of neigh- 

 bouring patches. The petechial spots of the nose and 

 mouth are larger and darker in colour, and more likely to 

 coalesce than in the simpler form of scarlatina. There is 

 great diflSculty in breathing and swallowing, and there is 

 loud and painful cough.
