Natxiralists indicate the number of teeth in the jaws of the maminifer* 

 CDS animals by figures placed in a particular position, thus : incisors or 

 cutting teeth \ means four in the upper jaw and four in the lower. — 

 Where teeth of the same character occur in both sides of the same 

 jaw, the number is indicated by a double set of figures, thus : canines 

 or dog teeth \ \ implies one on each side of the upper jaw and the 

 same in the lower ; molars or grinders f f means five in each side of the 

 upper and fire in each side of the lower jaw.
