394 ERUPTIVE OR PETECHIAL FEVERS. 



allowed in abundance, in order to support the animal strength. 

 When the secretions are restored to their natural condition, and 

 the soreness of the throat a little abated, a small ball containing 

 carbonate of ammonia — the ball being well oiled — may be given 

 two or three times a day with great benefit, and later on the 

 mineral tonics, with bark or quinine. If soreness of the throat 

 and cough remain after the subsidence of the rash and fever, 

 ulceration is to be suspected, and this can occasionally be 

 detected by an examination with the oral speculum. — (See 

 Principles and Practice of Veterinary Surgery, page 511.) It 

 may be combated by a blister to the throat, or by direct appli- 

 cation of the nitrate of silver solution to the part by means of 

 a sponge tied to a piece of cane. 



When suppuration has occurred, the abscess is to be opened, 

 as the abscesses of scarlatina often become languid, and do not 

 burst readily.^ 



Whenever the fever abates, and other signs of convalescence 

 appear, food of the most nutritious quality must be allowed in 

 moderate — not over-abundant — quantity. 



Exercise should not be enforced until all febrile signs have 

 disappeared, and the animal has to some extent regained its 

 strength ; even then much exercise is to be strictly forbidden. 

 I have seen the most severe and rapidly fatal purpura caused 

 by exercising the animal too soon and too severely. 



I have said nothing about the treatment of the external swell- 

 ings of the limbs. I am of opinion they should not be interfered 

 with, as they are but expressions of a condition of tlie blood 

 which does not endanger the life of the animal, and will dis- 

 appear spontaneously. 



The post mortem appearances are similar to those of purpura, 

 with the addition of inflammation and swelling of the throat. 



^ The frequency of abscesses in scarlatina points to the conchision that, in 

 addition to its own peculiar miasma, one or more of the cocci of suppuration is 

 present, — most probably the Staphylococcus pyorjenes alius.
