day. The first form of the disease is always marked by intense 

 yellowness of the membrane of the mouth, and also, to a less 

 extent, of that of the eyes and nostrils when the liver is affected ; 

 also by shivering fits. When the lar}mx and bronchial tubes are 

 principally affected, the cough is frequent and painful, and the 

 mucous membrane of the mouth, eyes, and nostrils is red instead 

 of yellow in colour, the breathing is commonly accelerated, and the 

 pulse quick and feeble. The dung is voided in small quantities and 

 dry, and the urine is high coloured. 



The symptoms are general appearance of dejection, rapid breath- 

 ing, discharge from the nostrils, sometimes confined only to one, 

 and more frequently the left ; flow of tears from the eyes, and 

 extremities cold. In this stage administer stimulants, with a mild 

 purgative, the stimulants every three hours. Should this prove 

 ineffectual, give one drachm of carbonate of ammonia largely diluted 

 in water, and given every two hours until the oppression is removed. 

 This is a good prescription for congestion of the lungs. 



At the first appearance of catarrh give for food all that is most 

 digestable, such as scalded and crushed oats, boiled caiTots, &c., &c. ; 

 give bran mashes with a teaspoonful of nitre, and, immediately, 

 a ball contaming 3drs. of aloes; and administer thrice daily Idr. 

 carbonate of ammonia in a pint of water until the symptoms subside. 



Treatment of influenza must always be either negative or stimu- 

 lating, never sedative or depressing in its effects. When it is 

 necessary to allay irritation, small dozes of opium may be given, 

 but the majority of cases do better without any narcotic treatment. 

 Counter-irritants are always beneficial when the lar3mx or bronchial 

 membrane suffers from inflammation ; and they are also indicated 

 when the lungs are congested, which is frequently the case in weak 

 animals. Mustard poultices are quite as effectual as blisters, and 

 may be safely applied to the throat, chest, or sides, if the state of 

 the breathing renders it necessary. Internal remedies will comprise 

 salines, with ammonia and vegetable tonics. A very good mixture 

 for the early stage of the disease is composed of carbonate and 

 nitrate of potash, one drachm of each, dissolved in a pint of water, 

 to which half an ounce of aromatic spirit of ammonia may be added. 

 When the prostration is exceedingly marked, sulphuric ether, half 

 an ounce, may also be added to the draught, and in many instances 

 an ounce of tincture of gentian may be advantageously substituted 

 for the ammonia. 



The horse may be tempted with any kind of food which is 

 obtainable. A preference is generally given to succulent diet : but
