37^ Veterinary Medicine. 



gation has enabled us to differentiate, according to their respec- 

 tive causes, a number of diseases (distomatosis, lung worms, 

 ank3dostomiosis, internal acariasis, chronic trichinosis, strongyli- 

 asis, etc.,) which were formerly classed as anaemias, and it seems 

 altogether probable that the onward progress of medicine will en- 

 able us to go farther in the same direction and to allot the remain- 

 ing unclassed anaemias to their proper etiological places. Some 

 may be unrecognized helminthiasis, others microbian disorders, 

 and still others, disorders in nutrition and sanguification from 

 different causes. 



The Symptoms are those of other forms of anaemia, but being 

 more obscure in origin and therefore less open to corrective treat- 

 ment, it is more likely to grow to an extreme development and fa- 

 tal issue. The weak pulse, irritable heart, debility, unsteady 

 walk with the hind limbs, hurried breathing and sweating under 

 exercise, watery, puffy eyes, dropsies in limbs and dependent 

 parts of the body, progressive emaciation, and weakness are even 

 more marked than in symptomatic anaemia. 



The treatment is in the main as for the other form alike in its 

 hygienic and medicinal bearing. In man recoveries have taken 

 place under arsenic combined with the iron. Arseniate of potash 

 and ferrum redactum in pill form, or tincture of chloride of iron, 

 and Fowler's solution in food or water, continued for a length of 

 time. Phosphated pepsin, and peroxide of hydrogen have seemed 

 to do well in some instances, and phosphorated oil is another re- 

 sort. W. Hunter attributes idiopathic anaemia to toxins derived 

 from microbes in the alimentary canal, as Sir Andrew Clark as- 

 cribes chlorosis to a similar cause. He prescribes beta-naphthol 

 as the least soluble and best antiseptic, in a dose of 5 grains daily 

 in mucilage for man (i drachm for horse or ox). Hunter fur- 

 ther found that a farinaceous diet protected the globules against de- 

 struction while a nitrogenous diet favored this. It may be noted 

 that long ago Delafond attributed anaemia in animals to the ex- 

 tension of the use of artificial fodders of the natural order legumi- 

 nosae which are rich in nitrogen.
