mont." Bojanns,* Prof. Owen says, first "drew the 

 attention of veterinary authors to it by his memoir 

 'De Dentibus Caninis Caducis/ &c. Bojanus never 

 found the lower deciduous canine retained beyond the 

 first year. The deciduous canine of the upper jaw, 

 being developed at a short distance behind the incisors, 

 is less disturbed by the eruption of the outer incisor, 

 but is nevertheless siied in the course of the second 

 year. The deciduous canines appear from Camper's f 

 observations to retain their place longer in the zebra 

 than in the horse." 



Monsieur Lecoq says: 



" The canine teeth are not shed, and grow but once. 

 Some veterinarians, and among them Forthomuie and 

 Kigot, witnessed instances in which they were replaced ; 

 but the very rare exceptions cannot make us look upon 

 these teeth as liable to be renewed. We must not, 

 however, confound witli these exceptionable cases the 

 shedding of a small spicula or point, which, in the 

 majority of horses, precedes the eruption of the real 

 tusks.'' 



Prof. C. S. Tomes says: 



" The milk teeth of all the ungulata are very com- 

 plete, and are retained late. They resemble the per- 

 manent teeth in general character, but the canines of 

 the horse, as might have been expected — their greater 

 development in the male being a sexual character — are 

 rudimentary in the milk dentition."
