then only can tliey prodnce tlie desired effect witliin a short

If disturbances of circuhition have been bronftht about 

 solely on account of a decreased tonicity of the arteries (see 

 Vol. I) the effect of cardio-tonics may be augmented by intrav- 

 enous injections of physiologic salt solution or of Ringer's 

 solution (4-6 quarts for a horse). The intravenous injection of 

 larger amounts of fluid may become dangerous in the presence 

 of cardiac weakness and may then lead to fatal edema of the 

 lungs (authors' own ol^servation). 



Fever does not, as a rule, require any special treatment, 

 except in the presence of hyperpyrexia, when cold sponging, or 

 irrigation or injections of cold water into the rectum may be 

 indicated. However, cold douches should not be used during 

 the cold season nor in very young or very debilitated animals. 

 Of antipyretics the following may be used: antifebrin (15-30 

 giu. for large, 1-4 gm. for smaller animals, 0.1 to 1.0 gm, for 

 carnivora pro dosi) ; phenacetin (the same doses) or antipyrin 

 (the same doses). Lactophenin, which is much higher in price, 

 may be given to smaller animals (0.5-1.0 pro dosi). With the 

 exception of phenacetin or lactophenin these drugs must be 

 used cautiously, since they may bring about collapse. The 

 salicylates are indicated much less (acid, salicylicum, sodium 

 salicylicum, salipyrin, salol, aspirin, dymal) since they often 

 produce intestinal" disturbances or irritate the kidneys. Tallia- 

 min (10 cc. intravenously) has not been effective in the treat- 

 ment of influenza-pneumonia of horses, neither have inhalations 

 of oxvgen as recommended bv Eberlein and Topper (Pr. VI).

Venesection, which Avas formerly practiced universally, may 

 bring temporary relief in the beginning; it does not, however, 

 influence the course of the disease at all, and is l)y no means 

 void of danger, on account of decrease of the tonicity of the 

 arteries. 



Delayed resorption may be stimulated by Priessnitz' axj- 

 plications and by diuretic drugs; of the latter we should use 

 preferably acetate of sodium or potassium (25-30 gin. for large, 

 3-10 gm. for smaller animals, 0.2-1.0 gm. for carnivora, two to 

 three times daily) ; diuretin, theozin, theophyllin (for carnivora 

 daily three tunes 0.2-0.5 gm.) ; iodide of potash (for large 

 annuals 10-20 gm. pro die per os) iodipin (for large animals 

 30-50 gm. subcutaneously), fibrolysin (large animals 10 cc. 

 every third day, dogs 2 cc. of the solution). The resorption 

 of the exu(Uite may be stimulated in protracted cases by punc- 

 ture of the infiltrated lung with the hollow needle of an injection 

 syringe; the procedure is similar to that used in exploratory 

 puncture of the thoracic cavity. 



Tlie repeated inhalation of atomized disinfecting fluids 

 (solution of corrosive sublimate 1 :2000-4000, 2 to 3% solution 

 of carbolic acid or creolin) may diminisli putrefactive processes
