for administering them. In the event that a veterinarian is not to be had 

 you should undertake the treatment yourself, and to aid you in remem- 

 bereing how to do it I will demonstrate the method on the animal before 

 us. 



First, bed the cow with clean straw, stirring up as little dust as pos- 

 sible. ]\Ioisten the udder and wash the teats thoroughly with an anti- 

 septic solution such as carbolic acid, a table spoonful to a quart of water, 

 or better Creolin of the same strength. Dry the parts with a clean towel. 

 then inject into each teat a solution of iodide of potash, 40 to 60 grants 

 dissolved in a quart of water. You will find it convenient to have four 

 one-quart ]\Iason fruit jars thoroughly cleaned and scalded, then fill with 

 hot water (soft water preferred) while the water is hot put into each 

 jar the 40 to 60 grains of iodide of potash, place on the cover and per- 

 mit the water to cool to the temperature of the body ; this can be hastened 

 by placing the jars in a vessel of cool water. The injection may be 

 made by means of an ordinary household syringe, either the Davidson 

 Inilb syringe or the fountain syringe. (I have also used with success 

 a two ounce hard rubber syringe, but the disadvantage of the latter is 

 that it requires to be fijled a number of times during the operation, and 

 greater care is necessary to prevent contamination.) The syringe should 

 be sterilized before using, by passing some of the carbolic or creolin solu- 

 tion through it, and washing the stem in the same solution. To the stem 

 of the syringe a milk tube is attached by means of a piece of soft rubber 

 lubing three or four inches long' and about the thickness of an ordinary 

 lead pencil. The milk tube is tied firmly into one end (the opposite end of 

 the tube usually fits snugly enough on the stem of the syringe to not 

 require tying.) The milk tube with the attached piece of rubber should 

 of course be sterilized in the antiseptic solution before using. Care should 

 taken during the injection to prevent the solution in the jars from be- 

 coming contaminated. If the fountain syringe is used, pour the fluid 

 into it outside of the barn away from the dust. The dust from the hav 

 and bedding contains bacteria wdiich if introduced into the udder may 

 cause a serious inflammation of that organ after the recovery of the 

 animal from milk-fever. 



If the Davidson bulb syringe is used, the suction tube must be in- 

 troduced into the mouth of the jar containing the solution of potassium 

 iodide. It will therefore be necessary to prevent contamination of the 

 solution by folding a clean towel about the jar and over the top. After 

 emptying the udder of milk, the milk-tube is passed carefully into the 

 teat and the solution forced into the udder; the tube is then withdrawn, 

 and the remaining quarters treated in the same manner. It is import- 

 ant to thoroughly knead the fluid into the udder, spend several minutes
