MEMOIltS OF TITB NATIONAL ACADEMY OF SCIENCES. 161 



1887- S8,by Sylvester Baxter (Salem, 18HS). In addition to all tins lie has liad the advantage of 

 a personal knowledge of the southwestern country, its antiquities and its people, extending over 

 a period often years. Helms had an equally long intimate personal acquaintance with the 

 director of the Ilemenway Expedition. In the autumn of 1887 he had the rare good fortune to 

 spend about a month with Mr. dishing at Camp Hemenway, in the Salado Valley, while the exca 

 vations at Los Muertos were being carried on. 



He might, therefore, had he so desired, have made of this introduction a more extensive and 

 pretentious essay. This is intended, however, not as a contribution to American archeology, but 

 merely for the convenience of the anthropologist who may desire to know something of the people 

 to the description of whose osseous remains this work is chiefly devoted. The author has intro 

 duced only some of the more easily explained discoveries of the expedition, and he has made many 

 statements without setting forth all the facts and arguments on which they are bused. The reader 

 must take some things for granted until Mr. Cushiug s final report appears. In referring to the 

 early Spanish writers and travelers the writer has been obliged to omit the proper bibliographical 

 notes, for the reason that he had not access to their books at the time of writing. 



In studying the crania and other bones described in the following pages, and in preparing this 

 report, I must acknowledge my great indebtedness to the following gentlemen of the staff of the 

 Army Medical Museum : To Dr. Jacob L. Wortman (who spent many months in the field collecting 

 and preserving the bones), for assistance in preparing the sections on the teeth and hyoid bone; 

 to Dr. D. S. Lamb, for assistance in preparing the section on the olecranon perforation; to Mr. 

 Porter Tracy, for his labor in taking measurements and his help in many other ways, and to Dr. J. 

 C. McConnell, for preparing the illustrations.
