CRANIA FROM THE MOUNDS OF FLORIDA. 443 



The crown, as shown in figure 37, is that of a tooth whose elements are 

 imperfectly defined by reason of the disposition of the grinding surface of each 

 cusp to be split up into folds, and the middle of the tooth to be everywhere 

 below the level of the borders. A tooth such as this is degenerating, and is on the 

 way to lose all its cusps and become a crater-like figure, whose elements cannot be 

 named and the walls of whose central depression are everywhere present. 



Description of the teeth of the Moore Crania, No. 1,784. Upper jaw. 

 Alignment disturbed by attrition, incisor forced slightly backward, worn transversely. 

 Lateral incisor in true alignment, the right more worn than the left. Canine much 

 worn, the right transversely, the left obliquely on buccal side. First premolar worn 

 for most part on buccal side. On the right side the second premolar has been nearly 

 lost ; the crown has been worn obliquely from before backward through to the pulp 

 chamber. The left tooth is worn evenly. The molars on the right are all in posi- 

 tion. On the left they are absent. The first and second are much worn on the 

 palatal side, the first into the pulp chamber, the crown being tilted inward. The 

 third molar is worn evenly. Lower jaw. The incisor line confined to the incisors. 

 The molar line includes the molars, premolars and canine. Incisors and canine 

 transversely worn. First premolar right transversely worn ; on left very obliquely 

 worn, buccal. Second premolar evenly worn, more indeed than the first. First 

 and second molars much worn, buccal, but not into pulp chamber. Third molars 

 absent. 



No. 1,781.. Upper jaw. The incisor line including the first premolar; the 

 curved molar line including the second premolar. The right incisors in different 

 alignment from the left, probably from attrition or disease, those of the right are 

 normal, but those of the left are thrown well forward and are without alveolar sup- 

 port, labial. The left lateral has been lost posthumously, the right is much pro- 

 truded. All the teeth are evenly worn to moderate degree excepting the first 

 molar, which is slightly inclined, palatal. The first premolar is more worn than the 

 second. — Lower jaw. The incisor line includes the canine and first premolar. 

 The molar line includes the second premolar. All the teeth are evenly worn to a 

 less degree than the upper, and nowhere into the pulp chamber, nor is the alignment 

 disturbed by attrition. With the exception of the first molar, which is worn 

 obliquely, lingual ; all are transversely true. 



No. 1,782. Upper jaw. The incisor line confined to the incisors. The molar 

 line includes the premolars and canine. The first molar is tilted palatal and the 

 buccal cusps are thrown from their sockets and have entered into the "wear." The 

 second molar is evenly worn ; the third molar is absent. — Lower jaw. The incisor 

 line includes the canines, the molar line includes the premolars. The first premolar 

 is more worn than the second. The first molar is much worn, buccal. The second 

 molar less evenly worn ; the third molar was small, but has been lost posthumously. 



No. 1,783. Upper jaw. The incisor line includes the canine. The molar line 

 includes the premolars and canine and is curved. The teeth had been perfect and 

 little worn, but many of the premolars and first and second molars subject to pos-
