176 INORGANIC AGENTS 



"Thick wind" and convalescence from acute bronchitis], pneumonia 

 or influenza are favorably influenced by arsenic. Arsenic is one of the 

 best agents we can prescribe in general debility and simple anemia and 

 may be conjoined with bitters or iron.

Arsenic is indeed the next best remedy to iron in anemia, and, in 

 pernicious anemia and leukemia, it is the remedy offering the greatest 

 chances of improvement, when given in gradually increasing doses until 

 horses are taking as much as one ounce of Fowler's solution twice daily; 

 and dogs one-half a dram.

 particularly useful in chronic squamous, or papular eczema, acne and 

 chronic urticaria, when given for a considerable length of time in small

 physiological action. 



In the human subject, arsenic is almost a specific in chorea, but does 

 not seem to yield such good results in that disease in dogs, usually asso- 

 ciated with distemper. Fowler's solution should be given to dogs with 

 chorea, in doses of two or three drops three times daily, and gradually 

 increased till the physiological limit is reached. The same treatment 

 should be tried in diabetes mellitus in dogs. Large single doses of arse-
