in his drinking water every six hours. Injections of warm water into 

 the rectum may facilitate the action of tlie purgative. Norwood's 

 tincture of veratrum viride, in 20-drop doses, should he given every 

 hour, and 1 dram of solid extract of belladonna every four hours, 

 until the symptoms become modified and the pulse regular and full. 



If this treatment fails to give relief tlie disease will pass into the 

 advanced stages, or if the animal has heen neglected in the earh* 

 stages the treatment must be supi)lanted with the hypodermic injection 

 of ergotin, in 5-grain doses, dissolved in a dram of water, every six 

 hours. The limbs may be i^oulticed above the fetlocks with mustard. 

 Cold water or ice-bags should now take the place of the hot-water 

 cloths on the head. Warm blanketing, to promote perspiration, is to 

 be observed in all cases in which there is no excessive perspiration. 



If the disease becomes chronic — encephalitis or meningitis — we must 

 place our reliance upon alteratives and tonics, with such incidental 

 treatment as special symptoms may demand. Iodide of i)Otassium in 

 2-drani doses should be given twice a day, and 1 dram of calomel 

 once a day, to induce absorption of effusions or thickened membranes. 

 Tonics, in the form of iodide of iron in dram doses, to which is added 

 2 drams of powdered hydrastis, may also be given every six or eight 

 hours, as soon as the active fever has abated. In all cases, after the 

 disappearance of tlie acute symi)toms, blisters (cantharides ointment) 

 should be applied behind the poll. . When paralytic effects remain 

 after the disappearance of all other symptoms, sulphate of strychnia 

 in 2-grain doses, in combination Avith the other tonics, may be given 

 twice a day, and be continued until it produces muscular twitching. 

 In some cases of paralysis, as of the lips or throat, benefit may be 

 derived from the moderate use of the electric batter}-. Many of the 

 recoveries will, however, under the most active and early treatment, 

 be but partial, and in all cases the animals become predisposed to sub- 

 sequent attacks. A long period of time should be allowed to pass 

 before the animal is exposed to severe work or great heat. When the 

 disease depends ui3on mechanical injuries the}" have to be treated 

 and all causes of irritation to the brain removed. If it is due to 

 stable miasma, unemic poisoning, pyaemia, influenza, rheumatism, 

 toxic agents, etc., they should receive promjot attention for their 

 removal or mitigation. 



Cerebral softening, abscess, or sclerosis, are practically inaccessible 

 to treatment, otherwise than such relief as may be afforded by the 

 administration of opiates and general tonics, and, in fact, the diag- 

 nosis is largely presumptive. 



COXGESTIOX OF THE BRAIN — MEGRIMS. 



Congestion of the brain consists in an accumulation of blood in the 

 vessels, also called hj^i^erpemia, or engorgement. It may be active or 

 passiN'e — active when there is an undue determination of blood or
