a loop, that loop is considered spoiled and the next loop outside
will be considered to locate the core. In each of the figures, the
point C indicates the core. Appendages will be further explained in
the section concerning loops.

Figures 46 to 48 reflect interlocking loops at the center, while
figure 49 has two loops side by side at the center. In all these cases
the two loops are considered as one. In figure 46, when the shoulder
line X--X is drawn it is found to cross exactly at the point of
intersection of the two loops. The two loops are considered one, with
one rod, the core being placed at C. In figure 47, the shoulder line
X--X is above the point of intersection of the two loops. The two are
considered as one, with two rods, the core being at C. In figure 48,
the shoulder line X--X is below the point of intersection of the
loops. Again the two are treated as one, with two rods, the core being
placed at C. In figure 49, the two are treated as one, with two rods,
the core being placed at C.

In figure 50, the delta is formed by a bifurcation which is not
connected with either of the type lines. The first ridge count in this
instance is ridge C. If the bifurcation were not present, the delta
would be a point on ridge C and the first ridge count would be ridge
D. In figure 51, the ridge which bifurcates is connected with the
lower type line. The delta in this would be located on the
bifurcation as designated and the first ridge count would be ridge C.
Figure 52 reflects the same type of delta shown in the previous figure
in that the ridge is bifurcating from a type line and then bifurcates
again to form the delta.
_A white space must intervene between the delta and the first ridge
count._ If no such interval exists, the first ridge must be
disregarded. In figures 53 and 54, the first ridge beyond the delta is
counted. In figure 55, it is not counted because there is no interval
between it and the delta. Notice that the ridge running from the delta
toward the core is in a straight line between them. If it were not, of
course, a
