with every animal they operate on. The differ- 

 ence can very often be noticed by bystanders that 

 would have them to think that some operators 

 have a mysterious influence over their animals. 

 Such, however, is not the case. The great secret 

 lies in avoiding the use of force. The horse will 

 resist any forcible movements of the hand while 

 going back into the mouth to examine the molars. 

 The violent or forcible means adopted while op- 

 ening the mouth will result in great damage or 

 injury to his gums, tongue and other parts of his 

 mouth. To use force in opening the mouth is not 

 necessary and should by all means not be resorted 

 to. When working on the lower jaw teeth the 

 hand should be placed in the interdental space to 

 guide the float along the inside of the lower mol- 

 ars. The mouth is opened a little more while fil- 

 ing the lower molar than what it is when working 

 on the upper grinders. 



To prevent the horse from fighting you, the 

 hand must not be used in the interdental space 

 to force the mouth open when the horse attempts 

 to close his mouth. The hand is only there to 

 guide the float and not to compel him to open his 

 mouth. The hand can not be injured if you will 

 keep it between the molars and incisor teeth at 

 the interdental space. Injury to the hand is gen- 

 erally caused by forcing the mouth open. The 

 moment you begin to use force the horse will then 

 start to resist your operation and move and turn, 

 thereby causing your hand to slip between the 

 molars, as the horse must have some free use of 

 the jaw while operating on the teeth. The opera- 

 tion on the teeth should not be a fight in strength 

 between the patient's jaw and the dentist's hand, 

 as your strength is not equal to that of the horse.
