PLATE I. FIG. 1. Below these, a central rectangular object features two rows of vertical lines, resembling a comb or a ruler. To the left of this central object is a vertical, elongated shape with a rounded top. At the bottom center, there are two small, vertical, spindle-shaped objects. On the right side, there are several other faint, irregular shapes, including a large, rounded form at the top and a smaller, oval form at the bottom right. The sketches are very light and appear to be preliminary drawings. Fig. 22. Fig. 23. Fig. 24. Fig. 25. Fig. 26. Fig. 27. Fig. 28. Fig. 29. Fig. 30. Fig. 31.
