DEXTITIOX FEVER. 93 



Of "Dentition Fevsr" Prof. Williams says ("Prin- 

 ciples and Practice of Veterinary Surgery," p. 470) : 



" Horses from three to four years old are more sub- 

 ject to this species of dental irritation than those of a 

 more tender age, and it is well known among horsemen 

 that they will stand more fatigue at a more tender age 

 than they will at this. The reason is because teething 

 is now at the hight of its activity. When the animal 

 is three years old, eight permanent grinders are being 

 cut, and four permanent incisors are in active growth 

 withm the jaws. At four years of age the same num- 

 ber of grinders are out, and the same number of inci- 

 sors are at a more advanced stage of growth within the 

 jaws, in addition to the canine teeth, which make 

 their appearance about this time. 



" No wonder then that the eruption of so many teeth 

 is a source of irritation and fever. The best treatment 

 is to throw the animal off work, turn him to grass if 

 the weather permits, or into a loose box in a well ven- 

 tilated spot, and give him rest until the process of den- 

 tition is completed. If the gums are red and swollen, 

 lancing them will prove a source of great relief." 



On page 503 Prof. Williams, in speaking of crib- 

 biting and wind-sucking, says: "Want of work and 

 the irritation of teething are generally the causes of 

 these vices."
