314 THE VETEEINARY SCIENCE. 



Symptoms.— After cattle have eaten it and it gets into the 

 blood it has such a peculiar contracting action on the heart, 

 arteries and other vessels that it weakens the circulation of the 

 blood so much that in some cases it stops it entirely in the legs, 

 ears and tail, and as soon as circulation in these parts stop they 

 die, rot and drop off, and later on in the disease the brain 

 becomes aflfected and the animal goes into convulsions and dies. 



Treatment. — Change the food entirely, bathe the affected 

 parts with luke warm water twice a day, rub dry and apply white 

 lotion to them after bathing. Give the following powder : 



Nitrate of Potash or Saltpetre ^ pound 



Ground Gentian Root | " 



Sulphate of Iron | " 



Mix and give a teaspoonful three times a day to a horse or 



cow; to smaller animals give one-half of the above dose. 



HOW TO DRY AN ANIMAL THAT IS GIVING MILK. 

 For a cow, give her a pound of Epsom salts in a quart of 

 luke warm water as a drench, then bathe the bag once a day for a 

 week with luke warm forge water (this is best obtained at a 

 blacksmith shop where they cool the irons). After bathing, milk 

 out a little of the milk once a day, on the ground, for a few days, 

 then milk a little out every second or third day for a few days, 

 then once every week or so for a while, and then stop milking. 

 The last time you milk her, milk the bag out dry. During the 

 time you are putting the cow dry, feed on dry, hard food. For 

 a mare, give eight drams of bitter aloes and a teaspoonful each 

 of ginger and common soda, dissolved in a pint of luke warm 

 water, as a drench. After you give the physic drench, let her 

 stand in the stable for a day or two, bathing the bag and 

 milking her the same as is given for the cow. In drying a sow 

 give a teaspoonful of sulphur in her feed twice a day, and if it is a 

 quiet sow bathe the milk glands with luke warm forge water once 

 a day for a week, and allow her to run'out. In drying a ewe give 

 a tablespoonful of Epsom salts dissolved in a half teacupful of luke 

 warm water, once a day for a week, and bathe her bag with forge 

 water, and milk her out in the same way as is given for the cow. 

 Why forge water has such a good effect in drying up the secretion 

 of milk is on account of the iron in it, which gets into it while 

 cooling the irons in the water, and this iron has an astringent 

 action on the milk glands. The reason the physic is given is to 

 clean the milk out of the blood.
