mothorax. As liquid is usually present as well it is hydro-- 

 pneumothorax. 



Tubercular and other forms of pleurisy have in certain cases 

 been superadded to the specific local lesions, by which such dis- 

 eases are individually characterized. 



Prognosis. Occurring in an otherwise healthy system and 

 especially if coutined to one side of the chest, pleurisy is not fre- 

 quently fatal, and under appropriate treatment recovery is often- 

 times rapid and satisfactory. A certain number of cases merge 

 into chronic hydrothorax, the inflammation apparently subsiding, 

 but reabsorption failing to take place. The hydrothorax may 

 last for months or even a year. 



Treatment, if seen during the chill and before inflammation 

 has been definitely established every effort must be directed to se- 

 cure its abortion, if possible. No time should be lost in placing 

 the patient in a warm comfortable stall or box, covering him with 

 woolen blankets and actively rubbing and loosely flannel bandag- 

 ing the legs. Warm drinks and warm injections must be given. 

 Half an ounce or an ounce of camomile or boneset in infusion 

 in two or three quarts of hot water, or in the absence of this 

 any of the carminatives, or etherial, alcoholic or ammoniacal 

 stimulants may be given. Pilocarpin in 7 grain dose hypodermi- 

 cally may promptly secure a revulsion of blood to the skin and at 

 once overcome the chill and prove a most effective derivative from 

 the pleura. Placing the legs in buckets of hot water, or the whole 

 animal in a hot air bath will often act equally well. Packing the 

 chest and even the abdomen in a blanket wrung out of very hot 

 water and covering it closely by one or two dry ones, or, better 

 still, by a rubber or other impermeable covering, will long retain 

 both heat and moisture, securing free cutaneous circulation, and 

 soothing in a most effective way the irritation in the chest. This 

 may be maintained as long as requisite to relieve the patient, and 

 then the body may be uncovered, apart at a time, rubbed dry and 

 covered with a dry woolen blanket. By using elastic circingles 

 over the compress they are adapted to the respiratory movements 

 and any restriction in the movement of the ribs is beneficial by 

 limitnigthe friction, pain and irritation in the pleura. 



In the second stage, when inflammation has already set in, the
