Four (Sets) Chalk Flints. Nos. 11, 12, 14, IS. 



H. 11. Trawled 20 miles S.W. of Eddystone. 



Some twenty chalk flints ; one weighs 6 lb., and is perfectly nnrolled. 



H. 12. Trawled 15 miles S.W. of Eddystone. 



A small flint about 8 oz. in weight. 



H. 14. Trawled 20 miles S.W. of Start Point. Weighs 31b. 2 oz. and 

 21b. 14 oz. respectively. 



H. 18. Trawled 17 or 18 miles S.W. by W. of Start Point. One flint

One Limestone. No. 13. 



H. 13. Trawled 15 miles S.W. of Eddystone. 



A small piece of buff-coloured limestone, riddled through and through by 

 molluscs and other marine borers. 



One Grit. No. 30. 



H. 30. Trawled 15 to 20 miles S.S.W. of Start Point. 



This is a small stone, measuring about 8" x 6" x 4", of fine grit, and may 

 well have been used for ballast. Its evidence is accordingly valueless. 



APPENDIX III. 



The observations of the late Mr. R. N. Worth,^ f.g.s. 



The bulk of the material Avas obtained for Mr. Worth by the late Mr. 

 Matthias Dunn, of Mevagissey ; it was all brought up entangled in the hooks 

 of bolters or long-lines. All bearings are magnetic. (Plate XVII.) 



"The evidence that the rocks were in situ Avhen entangled (partly by the 

 marine growths upon them, and partly by their irregularities and the holes 

 bored by Pliolades) is clear. With two exceptions only, the specimens 

 retained the characteristics of the original bedding." 



W. 1. S.E. Lizard, 10 miles. 



Fine-grained, soft, red Triassic sandstone, in layers 1^ to 2 inches thick. 



W. 2. S.E. Lizard, 15 miles. 



Triassic sandstone of coarser grain, mottled red and grey. 



W, 3. S.E. Manacles Rocks, 16 miles. 



Fine-grained soft sandstone, grey with a passing tinge of red in places, in 

 parts highly micaceous, containing both black and Avhite micas. 



W. 4. S.S.E. Falmouth Castle, 18 miles. 



Fine-grained, compact, red, jaspideous sandstone, much bored. The
