Layer with Triarthrns fragments iind spicules. Bearing, N. GO de- 
grees E. 
Calcareous bed. 
8. Layer with trilobite fragments. No direction. 
Layer with Diplograptus pristia. Bearing. N. 60-70 degrees E. 
Numerous layers with Endoceras shells. Bearing, N. 55-65 degrees 
E. All point east except in one layer where 5 point west and 2 east. 
9. Layer with trilobite fragments, rhabdosomes of graptoiites and 
casts of TroclioiioiKi. Behind the latter there are drift lines of frag- 
ments and before them lie fossils in a transverse position, as if arrested 
while drifting. The motion of the water must here have been quite 
strong, as the slabs appear furrowed in a parallel manner by the fossils. 
Bearing, N. 62 degrees E. Drift-lines extend towards S. 62 degrees W. 
Layer with Endoceras. Bearing, N. 65-70 degrees E. Two were seen 
to point east, none west. Behind the Endocoras shells, towards the 
west, drift-lines of trilobite fragments, etc., are found. 
Layer with Endoceras. Bearing, N. 70 degrees E. 
Calcareous bed, contains some complete specimens of TriarihruH 
bccki, while in the shale only dislocated fragments are met with. This 
difference in the pre.servation is probably due to the different velocity 
of the depositing water, the calcareous mud being a still -water deposit. 
10. Three layers with DiplograptuH pristis . Bearing, N. 60 degrees 
E. Sicular ends point both ways. 
Layer with Endoceras. Bearing N. 75 degrees E. 6 point east. 2 
west. 
Layer with Diplograptus pristis. Bearing, N. 70-80 degrees E. 
Layer with fragments of Triarthrus and scattered rhabdosomes, ar- 
ranged in a general easterly direction, but not so strictly as to approach 
parallelism of the fossils. 
Layer with numerous large Endoceras shells. Bearing, N. 35 degrees 
E. 36 pointing east, 2 west. 
Layer with many rhabdosomas of Diplograptus jtristis arranged in 
long drift-lines running N. 80 degrees E., while many stipes outside of 
the drift lines point in various directions. 
Below a great many layers with outcrops too narrow to give sufficient 
evidence. The rhabdosomes observed show an easterly direoticm. 
Calcareous bed. 
IL Three layers densely covered and parallel striated by specimens 
o\. Diplograpins pristis and Endoceras. Bearing, N. 70-75 degrees E. 
Apices of the fossils eastward. 
Layer with Diplograptus pristis. Bearing, N. 80 degrees E. Apices 
east. 
Layer completely furrowed by rhabdosomes of Di}>lograptus pristis. 
Bearing. N. 80-90 degrees E. 
Layer exposed with large surface, on the whole of which the direction 
of the rhabdosomes shows no change. Bearing, N. 70 degrees E. 
Layer with shells of Endoceras. Bearing. N. 65 degrees E. Four 
point east, none west.
