THE HORSE—GENERAL DISEASES AND INJURIES. 201 
Symptoms. 
the surface, followed by heat; convulsive movements and peculiar spasms 
Loss of appetite; thirst; cold and shivering; coldness of 
about the extremities; pulse and respiration quickened; temperature from 
105° to 110°; bloody dung; whitish discharge from the nose; high-col- 
ored, odorous urine. Though the symptoms are usually regular, they may 
be intermittent, the horse being seemingly almost well during their inter- 
missions. Recovery or death comes on rapidly. In fatal cases the breath- 
ing is exceedingly difficult, the convulsions in the back, loins and muscles 
of the eyes are violent; the temperature falls; loss of power ensues, and 
‘death is precipitated by a suspension of circulation. Carbuncles attend 
this fever, and are at first hot, tender, and easily indented, but soon become 
hard, painless and cool, terminating in ulcers. Yellow serum or blood 
may exude from some parts of the skin; the mucous membranes become 
puffy, stopped up, or streaked, with a bloody and offensive discharge finally 
coming from the nose. Sight, locomotion, eating, drinking and urination 
become impaired or impeded. Death may ensue ina few hours, or the 
animal may linger weeks, or even months. During the progress of the 
‘disease the animal hangs on the halter, leans against any object within 
reach, lies down, but soon rises again, turns the head toward the flank, and 
‘shows signs of pain in the belly. 
TREATMENT.—If symptoms of fever are chiefly noticeable, give ten 
drops of aconite every half-hour. For the general fever give one part of 
‘strong liquor ammonium causticum to ten of water every half-hour. For 
apoplectic symptoms belladonna and aconite may be used, fifteen or twenty 
minutes apart. For local swellings and carbuncles give arsenicum or 
phytolacca. If the dung becomes bloody, with straining during the dis- 
charges, and if the urine be bloody, give mercurius corrosivus. In the way 
of general care give a change of air, a comfortable stable and nutritious 
food. Remove an animal dying from th’ trouble, and cleanse the stall 
and all its furniture before admitting another horse. Carbolic acid has 
proved serviceable as a preventive. Further directions as to general care 
may be found under the treatment of this disease in the Ox. 
PURPURA HAMORRHAGICA.—ACUTE ANASARCA. 
This depends upon some unknown change in the blood or its vessels, 
perhaps both, by which the blood oozes into the skin and its tissues, and 
into the internal cavities and organs. It is supposed to be caused by ill- 
‘ventilated stables, over-work, bad or scanty food, damp stables; indeed, 
whatever checks proper blood-making; it often follows some catarrhal 
trouble.
