Their cooked meats and vegetables were made palatable 

 by a seasoning of salt. 



They were abundantly supplied with fruits, berries and 

 nuts, indigenous to this region. 



A sufficiency of water was easily obtained. 



Their lives were passed in an atmosphere invigorating and 

 free from taint. 



And. finally, their environment and culture were such as 

 made necessary a reasonable amount of physical exereise. 



I have dwelt on this phase of my subject at some length, 

 as 1 desire to show that these people were possessed of all 

 essential factors for producing a physically perfect race of 

 men. 



1 now ask your consideration of the teeth of an adult 

 Pueblo dweller. 



With exception of the superior left lateral incisor, all the 

 permanent teeth are present. 



Referring to the superior maxillary, there is noted a space 

 five mm. in width between the right lateral incisor and the 

 first bi-cuspid. The cuspid which should occupy this space, 

 has been crowded out of the arch, and is seen with its lingual 

 surface resting equally upon the buccal surfaces of the bi- 

 cuspids. 



The permanence of this space, and the abnormal position 

 of the cuspid, is doubtless due to the elimination of the tem- 

 porary cuspid having been retarded until after all the per- 

 manent teeth were fully erupted. 



The position in the arch that should be occupied by the 

 missing left lateral incisor is filled by the first bi-cuspid, while 

 the normal position of the bi-cuspid is occupied by the cuspid. 



There is nothing to indicate that the missing lateral was 

 ever erupted. Neither is it present in any part of the maxillary 

 bone. 



It is stated in Harris' "Principles and Practice of Dentis- 

 try" that transposition of tooth germs sometimes occurs. 

 Cases are cited in which the germs of lateral and central in- 

 cisors were transposed. Other eases involve the lateral incisors 

 and the cuspids. I have, however, been unable to find any 

 record of transposition of germs of the cuspid and bi-cuspid, 

 as is seen in this case. 



Non-development of teeth is not of such rare occurrence 

 as to be of special interest. Investigation will usually disclose 

 the abnormality to have been hereditarily transmitted. 



In the authority previously quoted, Dr. George Watt, an 

 eminent American dentist, states that he had knowledge of "a 

 family in which its female members for four generations lacked 

 the left superior lateral incisor.' 7
