On the other hand recovery does not preserve the animal 

 in a sound state. There may be adhesions of the lungs 

 to the sides, and possibly disease of the heart, its valves 

 or blood-vessels. 



Treatment should be prompt. If suffering animals are 

 continued at work they drop down dead. As a rule the 

 stimulative plan as recommended for influenza answers

 stages are passed. Blisters kill the patient. In order to 

 combat the chest irritation, use a stimulating embroca- 

 tion, and when the symptoms betoken tranquillity, the 

 stimulants with gentian may be again resorted to.

Scarlatina, or Scarlet Fever, appears occasionally in

 Two forms are recognised — Scarlatina Simplex and 

 Scarlatina Anginosa. 



Simple Scarlatina consists of a number of blotches in 

 the skin, particularly in those parts where it is thin and 

 least covered with hair, as the eyelids, lips, nose, &c. 

 At first these appear as small rounded pimples slightly 

 raised, on which the hair stands erect and separated. 

 The legs swell, and the mucous membranes, notably 

 that of the nostrils, are studded with scarlet spots of 

 variable size, which shortly discharge their serum, finally 

 changing in colour to yellow or a brownish hue. Sore- 

 ness of the throat is also present, and the appetite is 

 interfered with. In a few days the spots and blotches
