jected into the udder through the teats — an equal quantity into 

 each teat. The patient should be kept dry, warm and free from 

 excitement or noise, and in no consideration should drenching be 

 done so long as any acute symptoms are present. The patient 

 should be turned from side to side every four hours, taking care 

 to avoid injuring the udder, and the udder injection given again 

 in six hours^ if signs of return to consciousness are not present. 



In the hands of European veterinarians reports come to the 

 effect that 90 per cent, of 412 cases so treated made complete re- 

 covery. Various doses were experimented with, varying from 

 one-half to two drachms of the drug, and although the smaller 

 dose was repeated at shorter intervals the one drachm doses gave 

 best results, while a double quantity producing alarming symp- 

 toms and did not appear to exert any more favorable influence 

 over one-half the quantity, which appears perfectly safe. 



Hoio Does Potassium Exert Its Influence in Such Cases? — Long 

 before potassium iodine was associated in this way in the treat- 

 ment of milk fever, it was a well established fact that it exerted 

 a stimulating influence upon the base of the brain and great nerve 

 trunks when administered in large doses, and it is in this action 

 that it counteracts the depression present in that malady. It also, 

 no doubt arrests the decomposition in the udder when brought 

 into the direct contact with the udder content. Having a power- 

 fully stimulating effect upon the lympathic glands, it also has- 

 tens the elimination from the system of the offending poison. 



Form of Instrument Host Suitable for Its Application. — -Various 

 instruments have been recommended for the application of the 

 udder injection, but the instrument portrayed in the accompanying 

 cuts seems to fill the greatest number of requisites with fewer 

 objectionble features than any other we have seen. (See cut A.) 

 The large glass bottle. No. 1, holds the required quantity (half pint) 

 for one quarter (one teat). This bottle can easily be cleansed. It 

 can be brought to the proper temperature by immersing in hot 

 water for a few minutes previous to its use. The rubber tube (2) 

 is connected over the end of a glass tube which runs to the bottom 

 of a glass bottle (No. 1), thus minimizing the danger of air being
