170 REPORT—1905. 
c. The stratum of nodules containing crystals of sulphate of strontium 
upon the crystals of carbonate of lime occurs towards the lower part, and 
at about 14 feet above the white bands. 
p. The stem of a lacustrine plant, not yet named, was discovered by a 
fall of the cliff at p’. The real size is 1 inch to 1} inch in diameter. The 
side stems (none preserved) were about as thick asa quill pen. The joints 
oceur every 6 to 8 inches. The substance of the interior is soft sand- 
stone, the exterior a film of clay greenish in colour. Eight or ten side 
branches grow out at each joint.! 
gE. White Bands.—I merely mention these for the purpose of fixing 
levels on each side of the valley. Just above this level the marl passes 
into sandstone. In these bands the red colour is absent. 
F. Sawrian or Batrachian Band.—Mr. Johnston-Lavis discovered his 
Labyrinthodon Lavisi by a fall of cliff at F in High Peak Hill in August 
1875. The horizon of this stratum ought to strike the beach somewhere 
under Wind Gate ; but it is hard to say exactly, as the cliff is concealed 
by bushes and landslips. 
The Rev. 8. H. Cook in 1876 discovered a small piece of the same 
fossil bone at G at the fault where the saurian band comes up. He left 
it with me, and I afterwards forwarded it to Mr. Johnston-Lavis. 
Tie Movements of Underground Waters of North-west Yorkshire.— 
Sixth and Final Report of the Committee, consisting of Professor 
W. W. Warts (Chairman), Mr. A. R. DWERRYHOUSE (Secretary), 
Professor A. SMITHELLS, Rey. Ei. Jones, Mr. WautTer Morrison, 
Mr. GrorGE Bray, Rev. W. Lower Carrer, Mr. T. Farr.ey, 
Professor P. F. KENDALL, and Dr. J. E. Marr. 
Tue boreholes in progress at Turn Dub at the time of the presentation of 
the last report have now been completed, with the result that the 
existence of boulder-clay below the bed of the River Ribble at that point 
was conclusively proved. 
In all seven boreholes were put down, but owing to the extremely 
stony nature of the ground only one of these reached the bed-rock. 
This was on the right bank and some 20 feet from the river, and the 
limestone was reached at a depth of 8 feet below the level of the river-bed. 
A full account of the work of the Committee has been published in 
the ‘Proceedings of the Yorkshire Geological and Polytechnic Society,’ 
Vol. XV., Part II., pp. 248-292. 
The work of the Committee is now completed, and the grant has been 
spent, with the exception of a small balance, which has been returned to 
the Treasurer. 
1 Mr. A. C. Seward has examined the drawing of the plant, and states that 
the plant may belong to Schizonewra. Mr. Hutchinson described and figured his 
specimen in the Transactions of the Devonshire Association, vol. xi. p. 383, in 
1879.—J. LoMAs.
