ASTRAGALUS, 
In all we have seven well-preserved astragali, three right and four left. Their 
size corresponds throughout to those of the horses already mentioned. 
As is known, Forsyth Major points out that in the fossil horse the length 
of a segment of the inner end of the navicular surface of the astragalus, counted 
from its intersection by an imaginary line representing the continuation of the 
outer surface of the inner condylus, is considerably shorter than in recent horses, 
and he illustrates this in a table, from which we have extracted some points giving 
the relation of the length of the inner segment of the navicular surface referred 
to its full length, which is taken as roo. 
Relation of length of inner segment of navicular surface of astragalus to tts full length 
(expressed in percentages).
