Articular Facets for Astragalus 
As to visual observations on the os calcis, the greatest interest 
attaches probably to the number and conformation of the articular 
facets for the astragalus. These facets may be two in number, ante- 
rior and posterior. But the anterior facet may be divided into two 
by a ridge; or it may be replaced by two facets, anterior and median, 
completely separated by a narrow to moderately broad groove or 
space; or, finally, in place of the single oblong anterior facet there 
may be a small to rudimentary anterior and a medium sized 
median facet, separated by a broad and deep notch. 
The percental distribution of these facets among the Munsee, the 
Arkansas and Louisiana mound Indians, and the United States 
whites, is given below. There is a remarkable similarity in the 
frequency of occurrence of the two main forms (two and_ three 
facets) in all three groups among the males, but the females show 
slight irregularity.
