SOUND AND UNSOUND HORSES 



At certain ages they form a most reliable 

 guide. 



The fourth, fifth, and sixth molars 

 appear as permanent teeth, whilst the 

 first, second and third are replaceable ones. 



These teeth appear in the following 

 order : — 



Nine Months.-- Th.^ fourth permanent 

 molar breaks through the gum, and at 



One Year it rises to the level of the 

 three temporary ones in front of it. 



One Year and Six Months. — The 

 fifth permanent molar is through, and at 



Two Years it is level with the fourth 

 permanent molar. 



Two Years and Six Months. — The 

 first and second temporary molars are 

 shed, if not, by the time the colt reaches 

 two years and three-quarters (rising 

 three). 



Three Years. — First and second per- 

 manent molars fully up. 



Four Years. — Third temporary molar 



1-3
