DISEASES OP THE RESPIRATORY SYSTEM. 159 



Absence of signs of pneumonia, pleurisy and bronchitis, which 

 are febrile affections. 



What is the treatment? 



It is incurable in the majority of cases, but many animals are 

 benefited very much by special feeding, and by medicinal agents. 



First we usually give a dose of physic — a purging-ball of aloes ; 

 these animals surfer with indigestion, flatulence, catarrh of the in- 

 testines, and the like, and a purge gets rid of this indigestible food. 



By careful attention to the diet we may lessen the symptoms. 



When it is due to dry, dusty hay, limit the quantity of hay and 

 dampen it with water, or with salt-water. 



In some cases wet the oats. 



The medicinal remedy is arsenic. In Europe the people eat 

 arsenic in order to enable them to climb the mountains better. 



Arsenic prevents destruction and elimination of the oxygen 

 carriers. 



We use arsenic best in the shape of Fowler's Solution (liquor 

 potassse arsenitis), also called liquor potassii Fowleri; this consists 

 of eighty grains of arsenic, eighty grains of potassium carbonate, 

 and water to make a pint; one fluid ounce can be given as a dose, 

 and this contains four (4) grains of arsenic. The dose of arsenious 

 acid varies from two to seven grains. 



Fowler's solution is colored with lavender to keep people from 

 drinking it by mistake ; give one ounce three times a day ; this will 

 often relieve some of the most urgent symptoms. 



Nux vomica, iron, potassium iodide, are often beneficial, as 

 are internal antiseptics and stomachics.
