THE LUNG PLAGUE. 45 



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 and 

 three-and-twenty per minute, a third abstraction of the same quantity 

 of blood must be practiced. If the pulse becomes strong and full, the 

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

 the respiratory 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 is added to this barley tea, and one liter of 

 this mixture is given, alternatively with the emetic every three hours. 



Marshmallows, linseeds, or coarse bran, are to be made into a decoc- 

 tion, and administered in the form of four injections daily. This same 

 material may be used warm to steam the animal's nostrils, bj- 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, during 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 indicate a yellow or paled and infiltrated asj)ect of the 

 conjunctiviB must be bled to the extent of one liter or a Liter and a half 

 daily, 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 or foiu* i)ounds two or three 

 times dail3\ The emetic draughts are to be i)ersevered in, the hodj Avell 

 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 maybe found economical 

 in some parts. If these cannot be had, a blistering tincture may be pre- 

 pared, as follows : Powdered cautharides, two ounces ; powdered euphor- 

 bium, one drachm ; alcohol, one-half pound. The three substances 

 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 effu- 

 sion, and the lung tissue is engorged and hepatized, no hopes can be 

 entertained of the animal's recovery. 



When the lung disease commences by an active inflammation of the 

 bronchial tubes, the jugular vein must be freely opened and from six to 

 ten pounds of blood abstracted ; other emissions, from four to eight 

 pounds each, must be repeated for two or three days each. If the 

 inflammation continues and spreads to the lung tissue, the dry rubbing,
