NOTES ON ODONTOMES.

which have both the form and structure of equine molars, the 
fangs of one of which is shown marked A, situated just above 
the bony palate midway between H and B in Fig. II. 
The temporary premolars having developed and erupted 
normally, as have also the molars, it must be concluded that 
the aberrations had their origin in connection with the devel¬ 
opment of the germs of the permanent premolars, only one of 
which had apparently developed and its eruption prevented by 
the growth of odontoid masses between its crown and the tem¬ 
porary fang. 
FIG. IV. 
In our prior contribution we asserted that the prognosis of 
odontomes was very favorable under proper treatment. In a case 
like the last, had it been taken in time, the animal’s life could 
probably have been saved, though at the expense of such great 
deformity as to nullify its value. 
The first case related, though ending fatally, could have 
been favorably operated upon at an earlier date. The one case 
is extreme in its gross aberrations, while the other is no less ex¬ 
treme in point of neglect. 
In the contribution cited we laid down as the rule of first 
importance in procedure that we should not apply force either 
by means of forceps or punch to an erupted tooth which might
