DISEASES OF THE RESPIRATORY ORGANS. 89 



and percussion the increase or decrease of solidification {/lepa- 

 iization) of the lung may be followed from day to day excepting 

 m the parts covered by the thick, muscular shoulder. In this 

 way aggravation and improvement can be noticed. A yellowish 

 or whitish discharge from the nose comes on as the disease 

 advances. 



Treatment. — Give a pure, dry, airy box, with windows or 

 doors turned to the sun or away from the direction of prevailing 

 winds, clothe warmly, and flannel-bandage the limbs, or even 

 rub them with ammonia and oil. The hot rugs advised for 

 congested lungs may be applied, and when removed let it be 

 done a little at a time, and the part rubbed dry and covered by 

 a dry blanket. Or a mustard poultice may be applied to the 

 sides of the chest. Large injections of warm water and drinks 

 of warm gruel may also be given. A laxative is often beneficial 

 in the more active forms of the disease, but should be given 

 cautiously as in bronchitis, and rejected when there is low 

 fever and much depression. Neutral salts (nitre, acetate of 

 potassa, bicarbonate of soda), should be given with sedatives 

 (belladonna, henbane, tincture of aconite, digitalis, or white 

 hellebore ; in pigs and dogs, tartar emetic), or if there is much 

 prostration, or when the fever has in the main subsided, stimu- 

 lant diuretics (sweet spirits of nitre, liquor of acetate of am- 

 monia), repeated three or four times a day. The sides should 

 be blistered with a pulp of the best ground mustard in water, 

 or Spanish flies, or in cattle and swine, mustard and turpentine, 

 and the blister may be repeated with advantage in protracted 

 cases. When in severe cases the blister refuses to rise, the 

 skin may be first warmed with rugs wrung out of boiling water, 

 and then the application of the blister made. Or a hot 

 shovel held near the blistered surface may determine an active 

 flow of blood to the skin and the rising of the blister. When 

 well risen the surface must be kept soft by sweet oil or fresh 

 lard to favour healing. In chickens it is advised to open the
