much work in this line, particularly in the United States, is as yet un- 

 published. The repeated discoveries of skeletal remains of early 

 man have in particular stimulated research in this direction. Not- 

 withstanding all this, however, we are still far from a satisfactory 

 grasp of the evidence which the bones embody. The reasons are, 

 in the first place, that the gathering of skeletal material has always 

 lagged behind that of the skulls, so that even today most anthropologi- 

 cal collections are relatively poor in that respect, which hinders com- 

 prehensive and conclusive investigations. Besides this, the bones of 

 the skeleton present many features and correlations the study of which 

 demands large series of specimens, and in many cases also the presence 

 of all the important constituents of the skeleton or the bones of the 

 two sides of the body, conditions which are realizable with difficulty 

 even among the Whites, not to speak of other peoples. The field will 

 long remain, therefore, one of a very considerable importance, and no 

 pains should be spared to develop the technique of osteological in- 

 vestigation. 



The scheme here presented rests on the same principles as those 

 presented before for anthropometry and craniometry. It utilizes 

 the most useful procedures of other scholars, supplements these 

 where extensive individual experience warrants, leaves aside every- 

 thing superfluous or of value only in special studies, and aims at the 

 utmost simplicity. 



INSTRUMENTS 



The matter of osteometric instruments has already to some extent 

 been dealt with in the section on Craniometry (Vol. II, 1919, p. 50), 

 The essentials are few. They are the Broca's osteometric board (pi. 

 1), the small compas glissiere and for a few measurements also the large 

 sliding compass; but other instruments may be needed for special 

 investigations.
