and give milk as in health, will in three or four days cease to cat, ruminate, and give 

 milk. They will moan and indicate all the signs of pleuropneumonia at a period when it 

 is severe and often incurable. 



An animal chosen with care in the earliest stage, and isolated, must be placed on low 

 diet, and allowed only a little green grass or hay. Six to eight pounds of blood must be 

 drawn, and this repeated eight or ten hours later. As soon as the blood has ceased to flow 

 the body and limbs must be rubbed for half an hour with hay or straw wisps, and a good 

 covering must be thrown over the body. Three hours after the first bleeding, and every 

 two hours afterward for sixteen hours, a draught must be given, consisting of one drachm 

 of tartar emetic in a quart of river or spring water. For animals under two years of age 

 the dose of the tartrate of antimony should be half a drachm, and for animals from three 

 to eight years of age a drachm and a half each time. 



After the second bleeding the draughts are continued, and if, after twelve hours, the 

 respirations have not been lowered to twenty or three-and-twenty per minute, a third ab 

 straction of the same quantity of blood must be made. If the pulse becomes strong and 

 full, the breathing less frequent, the mucous membranes paler, and especially if the respi 

 ratory murmurs are less loud, it may be considered that the animal is saved, and that- its 

 convalescence will be short. 



Independently of the bleedings and the administration of emetic tartar, about fifteen 

 liters* of water, with three liters of barley, may be boiled, throwing off the first water and 

 adding thirty liters more. Two pounds of sulphate of soda are added to this barley tea, 

 and one liter of this mixture is given, alternately with the emetic, every three hours. 



Marshmallow, linseed, or coarse bran, is to be made into a decoction, and admin 

 istered in the form of four injections daily. This same material may be used warm to 

 steam the animal s nostrils, by placing it in a stable pail and covering the animal s head 

 and the pail with a large cloth. 



These measures, says Delafond, must be continued for three or four days indeed, dur 

 ing the entire first period of the disease ; and it is rare that the respiratory movements do 

 not return to their normal condition. If the patient purges, injections of bran decoction 

 are recommended. 



Animals that present a yellow or pale and infiltrated aspect of the conjunctivas must 

 be bled to the extent of one liter or a liter and a half daily only, as heavy blood-lettings 

 are prejudicial in such cases. 



When pleuropneumonia begins by an inflammation of the pleura, the animal must be 

 bled to the extent of two to four pounds two or three times daily. The emetic draughts 

 are to be persevered in, the body well rubbed and clothed, and the sides of the chest must 

 be rubbed with hot vinegar, or with a mixture of three ounces of ammonia to one ounce of 

 vinegar. An infusion, in two liters of hot vinegar, of a pound of white or black hellebore, 

 or of the large horse-radish sage, may be found economical in some parts. If these can 

 not be had, a blistering tincture may be prepared, as follows : Powdered cantharides, two 

 ounces ; powdered euphorbium, one drachm ; alcohol, one-half pound. The three sub 

 stances must be left in a bottle for some days, and then filtered. 



If the symptoms subside, the animal is to be kept under shelter and on moderate 

 diet. If, on the contrary, the pleurisy terminates in effusion, and the lung tissue is en 

 gorged and hepatized, no hopes can be entertained of the animal s recovery.
