PLATE IX 
Fig. 21. Leveilleites hartnageli Foerste. From Credit Forks, Ontario. View 
of frond A in figure 21 on plate VI, enlarge 14 diameters. The median rachis-like 
black film with traces of corresponding lateral films are shown. 
Fig. 25. Leveilleites hartnageli Foerste. From Credit Forks, Ontario. The left 
hand figure is enlarged 4 times, and the middle figure is enlarged 8 times. The 
middle figure is an enlargement of frond A in the preceding figure, and both figures 
are enlargements of figure 25 on plate IV. These enlargements show the median 
rachis-like black films of the fronds and of their lateral lobes, and the reticulated 
structure of the fibrous mass forming the fronds. Along the left margin of the 
middle figure on this plate the hair-like fibers attached to the frond are visible in 
the photograph, but do not show up well in the photoengraving.
