each having marginal serrations, and a median square key pattern. 
One side of these triangles is continued into a line from which hang

their angles into projections to which are appended round dots with 
three parallel lines. The median portion, or that in the reentrant 
Fia, 328—Double compound triangle; median rectangle

the median portion replaced by a rectangle, and in which the key
