CHAPTER VI. 



DENTAL CYSTS AND SUPEKNUMERAKY TEETH. 



Teeth growing in various parts of the Body. Some Cysts more 

 Prolific than others, Producing a Second, if not a Third, 

 "Dentition." Reports and Theories of Scientific Men. 

 Cases of Third Dentition in Human Beings. 



THE development of abnormal teeth in different 

 parts of the body (the human body as well as those of 

 the lower animals, particularly the horse), is not the 

 least interesting feature in the study o dental science. 

 To judge from the reports that follow, one would think 

 the tooth-substance in some horses was an unknown 

 quantity. It would be interesting and useful to know 

 whether in such cases the natural teeth are in a per- 

 fectly healthy state, and whether the temperature is 

 natural, instead of being increased, as during certain 

 periods of teething. While the study of these teeth 

 may not be of paramount importance, it serves to 

 further illustrate the physiological relations of the den- 

 tal system, and ought to assist the surgeon in more 

 correctly diagnosing diseases. 



Surgeon George Fleming, of the Royal Engineers, 

 contributed a valuable paper entitled " Dental Cysts, 

 or Tooth-Bearing Tumors," to "The Veterinarian" for 

 1874 (p. 692), the substance of which is as follows :
