SUMMARY 



Tetanus or "lockjaw" is a germ disease that is common in 

 horses and mules. It also attacks man. 



The disease is usually caused by the germs getting in a 

 wound. The soil about stables and corráis that is contaminated 

 with animal excretions is liable to contain the germs of tetanus. 



The symptoms of tetanus are contraetions of the muscles that 

 makes movement difficult or impossible. 



Tetanus can usually be prevented by injecting a bottle (30 

 grams) of veterinary antitetanic serum as soon as the wou'nd 

 is discovered or before a surgical operation. 



Many cases of tetanus can be cured by injecting 30 grams 

 of veterinary antitetanic serum. This should be followed in 

 twelve hours with another dose, and then one dose every twenty- 

 four hours until the animal improves. In the absencé of 

 antitetanic serum or in conjunction with it, inject hypodermic- 

 ally five grams every six hours for the first two days of a 

 solution of 25 grams puré carbolic acid, 25 grams glycerine, 

 and 50 grams distilled water. After the first two days i'n'jeet 

 five grams every twelve hours. 



Clean the wound twice daily and apply thoroughly a solut- 

 ion of five grams of puré carbolic acid dissolved in 100 grams 

 of water. Give the animal soft laxative food and all the fresh 

 water it can drink. Keep the animal quiet in a clean place and 

 do not give medicines by the mouth or nose.
