_Treatment._ In slight cases of cerebral hyperæmia, it may be sufficient to apply cold to the head with a stimulating fomentation to the limbs, and an active purgative, with chloral or bromides. Ergot in full doses has often an excellent effect. In the more acute types of the disease, bleeding is the first and most efficient measure. A full abstraction from the jugular will relieve the vascular tension and relieve the circulation on the brain. It has been counselled to avoid this when comatose symptoms have set in, and in some prostrate conditions a large and rapid abstraction of blood may fatally increase the prostration. In other cases, however, the less rapid abstraction will improve at once the intracranial circulation and nutrition, and solicit the reabsorption of the exudate which produces sopor and coma. A purgative is one of the most efficient derivatives, the determination of an excess of blood to the bowels and of an abundant serous discharge into their interior acting as a valuable depletion, and abstraction of blood from the over-excited brain. At least a half more than the usual dose must be given, and may be supplemented by an injection of glycerine or a hypodermic exhibition of eserine. It is best to avoid too drastic or irritant purgatives as the cerebral congestion may be aggravated by the irritation, as it often is induced in severe indigestions. For the horse, aloes and podophyllin, or for ruminants, omnivora and carnivora castor oil may be resorted to. The patient must be placed by himself in a dark, cool, well aired building, and when able to resume feeding must receive an easily digested, non-stimulating diet; for horses or cattle gruels, wheat bran mashes, pulped roots, or green food; for dogs and pigs, gruels, mush or milk. Any sequent paralysis must be treated on general principles. MENINGO—ENCEPHALITIS. STAGGERS.
