exceedingly few insects were obtained. The insects might be found 

 further to the dip, but the encouragement to prospect does not lie 

 in this direction, but, as stated above, along the outcrop, the position 

 being shown in the photo, on Plate 9. The weathering of the bed 

 near the outcrop has developed a large number of lamination planes, 

 so that a much larger area of surfaces can be examined by splitting 

 the shale than in the lower greenish part of the bed where the laminae 

 are bound together and difficult to separate. Possibly the insects are 

 no less rare in the greenish rock at the bottom of the quarry than in 

 the weathered portion near the outcrop, the character of the lamina- 

 tion in the former only preventing their discovery. The coating 

 on the surface of the fossil impressions has been previously referred 

 to. Sometimes this coating is a film of very fine clay, which, when 

 carefully removed with water and a camel's-hair brush, is found to 

 have covered delicate microscopic structures. In some specimens 

 particles of bright carbon from the original elytron have been pre- 

 served, although very little of the original design remains to be 



seen.
