14:2 The Horse Farrier. 



piration on each side of the horse, you may know very sat- 

 isfactorily whether one or both lungs are diseased. 



If the disease still progresses, those inflamed and heap- 

 atized portions sappurate, an abscess forms, and matter 

 may be discharged by coughing. 



In pleurisy, the air cells are not implicated, and the res- 

 piratory murmur will be heard at first over the whole of 

 the lungs. (The reader will bear in mind that the thin 

 membrane which covers the lungs and lines the in- 

 side of the chest is called the pleura, and that in- 

 flammation of this membrane is pleurisy.) A dry friction 

 sound will be heard in the commencement of pleurisy. 

 Plastic lympth may exude from the inflamed surface, or 

 the vessels may relieve themselves by pouring out water 

 between the lung and side, the respiratory murmur disap- 

 pearing in proportion as the water accumulates. 



Treatment. — This may be commenced by a good 

 bleeding, but to be of much service it should be done at 

 the commencement of the disease, followed by emetic 

 tartar and nitre. A drachm of the former and three of the 

 latter every eight hours, equalize the circulation, by rub- 

 bing the extremities, giving light laxitive food, as bran 

 mashes ; throw warm blankets over the animal, hanging 

 down to the floor, and place vessels of hot water in which 

 put hot stones or bricks, and sweat freely, also opium and 

 calomel, one scruple of the former and two of the latter 

 twice a day. The sides of the chest may be thoroughly 

 blistered, the irritation on the surface diverting the in- 

 flammation from the lunors. 



There is another article very efficient in this disease in 

 the human subject, and I think it must operate equally 

 favorable on animals. I refer to the Veratrum Viric!*). 

 The tincture, as prepared by Dr. W. C. Norwood, or the 

 extract, as prepared by Tilden & Co., N. Y. 



This medicine may confidently be relied on to control 

 the actions of the heart and arteries, reducing the pulse 

 in the human subject from 120 beats in a minute to 60 

 or even 40. 



In giving this remedy, the pulse should be closely
