1 6 DISEASES OF THE DOMESTIC ANIMALS 



solution of arsenous acid (U.S.P.) twice daily may be given 

 cattle- and. horses, unless catarrh and edema about the eyes and in- 

 digestion are induced. The dose at first should be about T /i ounce 

 of Fowler's, solution, or' solution of arsenous acid — twice daily — 

 and increased to the above and, after a week or two, diminished 

 again. Either solution is readily taken on the food. 



Progressively severe forms of anemia tending to become- fatal 

 are sometimes classed as pernicious anemia — as those due to intes- 

 tinal parasites; — but we have considered only that form due to un- 

 known causes as pernicious. In pernicious anemia, diluted hydro- 

 chloric acid (H. & C, 3 i-ii) is commonly indicated, as atrophy of 

 the gastric mucous membrane often occurs; it may be combined to" 

 advantage with solution of arsenous acid and given in drench, well 1 

 diluted, after meals. In anemiai following disease and hem- 

 orrhage, the use of alcohol and bitters to stimulate appetite and 

 digestion is. advisable for a week or so before beginning with iron. 



In the anemia of rickets in young animals the syrup of ferrous 

 iodide (puppies, 10 to 15 minims) is the best preparation. 



In all secondary anemias — and these are the common anemias 

 — the chief desideratum is the discovery and removal so far as pos- 

 sible of the cause. The causal diseases are noted above and the 

 reader is referred to the. special headings, of these disorders under 

 which their treatment may be found- 



Infectious Anemia (Pernicious Anemia,. Swamp Fever, Ty- 

 phoid Fever of Horses, Malaria of Horses*). This is an infectious 

 disease attacking horses, asses and mules and characterized by a pro- 

 gressive, pernicious anemia with remittent fever, weakness, emacia- ' 

 tion, polyphagia, and polyuria. It is prevalent in Minnesota, 

 Kansas, Nebraska, Colorado, Wyoming, Montana, North Dakota, 

 Texas and Manitoba. 



This disease appears to be enzootic in certain localities for
