NOTATION AND SYMBOLS OF TEETH. ^15 



The symbols of the teeth are fewer, are easily under- ^ 

 stood and remembered, render unnecessary the endless 

 repetition of the verbal definitions of the parts, harmonize 

 conflicting synonymes, serve as a universal language, and 

 express the author's meaning in the fewest and clearest 

 terms. The entomologist has long found the advantage 

 of such signs as °^ and 9 , signifying male and female, and 

 the like; and it is time that the anatomist should avail 

 himself of this powerful instrument of thought, instruc- | 

 tion, and discovery, from which the chemist, the astrono- 

 mer, and the mathematician have obtained such important 

 results.
