vessels, when those agents have been long and injudiciously given, 

 it is recorded that the marninae of women and the testes of men 

 have almost disappeared. A case illustrative of the effects of 

 iodine on the glandular system was related by Mr. Wardle, who 

 employs this agent largely, and with considerable success. He 

 had been for some weeks exhibiting the iodide of potassium, and 

 also applying it externally to a bull for an enlarged parotid gland. 

 The reduction of the swelling having been accomplished, his at- 

 tention was directed to the testicles of his patient, which had be- 

 come so much diminished in size; and it was also found that the 

 animal had no desire to copulate. Four months generous feed, 

 however, effectually restored the parts to their pristine state. 



In chronic enlargements of the submaxillary, parotid, mam- 

 mary, and other glands; in tumors of long standing; for thick- 

 ening of the integuments, and indurated swellings about the joints, 

 in all our domestic animals, and for unhealthy ulcerated surfaces, 

 the use of iodine and its compounds is indicated, combining both 

 their internal and external employment. The latter should be 

 accompanied with friction; and so soon as soreness is induced, the 

 application of the compound must be suspended. A desquama- 

 tion, or scaling off of the cuticle, or skin, usually follows this, and 

 a reduction of the swelling will soon after be perceptible. Unfor- 

 tunately, it is too often the case that, if the expectations of the 

 practitioner are not at once realized, the agf nt is discarded as use- 

 less. Now, the compounds of iodine rank a nong those substance 

 whose operation is slow, but which, at the same time, constitute 

 in important class, as their effects are permanent." 



Influenza, or Epizootic Catarrh. 



Influenza is a disease of a catarrhal character, always accompa- 

 nied by great weakness or debility. It is apt tc migrate from one 

 tissue to another, and thus produce various complications. In sta- 

 bles that are badly ventilated, or over-crowded with horses, the 

 malady is apt to make sad havoc, and assume a malignancy ending 

 in typhoid or typhus fever. 



In some cases the heart or lungs become congested, and thua 

 their function is embarrassed. The blood accumulates carbon, the 

 heart fails to propel, and the lungs to vitalize the blood. This 

 state demands stim ilants of a character that shall excite v'tal action.
