ment." Bojanus,* 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 shed 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."

 specimen is from the collection of Dr. Richard A. Finlay, of New York. 

 He also has an excellent specimen showing the canines at birth, peeping 

 through the bone, as it were. 



The deciduous canines appear to be as natural teeth as the 

 incisors, but they are so small that they usually escape obser- 

 vation, and are besides easily lost. Prof. Tomes truly says 

 they" are rudimentary." Owen, Tomes, Frothomme, and 

 Rigot, as well as Bojanus and Camper, recognize them as 

 teeth, but Lecoq does not. The latter compares them to " a 

 small spicula or point," but admits that they are shed, which 

 latter fact is prima facie evidence of his error.
