330 REPORTS ON THE STATE OF SCIENCE. 
the fact that there is no known outcrop in the neighbourhood which could 
have yielded the specimens. 
Notes are promised for next year’s report showing that, just as has 
proved to be the case with the Upper Cretaceous belemnites, some of the 
Liassic ammonites of the Drift of Holderness appear to be aliens in 
Yorkshire. 
The Committee welcome the promise of renewed activity on the part 
of the Belfast Naturalists’ Field Club, that has done much good work in 
the past. 
A considerable change of the personnel of the Committee is necessitated 
by the retirement of Dr. Marr from the position of Chairman, which he 
has held since the year 1899, and of Professor P. F. Kendall from the 
Secretariate, to which he succeeded upon the retirement of the late 
Dr. Crosskey. 
The Committee ask for reappointment, with Dr. A. R. Dwerryhouse 
as Secretary, and Professor Kendall as Chairman.

Reported by H. Cupin and G. GRACE. 
Bentley, near Doncaster.—In the sinking of the Bentley pit, two miles 
north of Doncaster, boulder clay has been passed through at a depth of 
55 to 75 feet below O.D. The boulders are principally Permian sandstone. 
There are grits, gannisters, and Carboniferous limestones. Coal Measure 
shale with Anthracomya Phillipsi also occurs. 
Tickhill, near Donzaster.—In a distance of two miles the South York- 
shire Joint Railway has opened out four cuttings through boulder clay. 
The most southerly cutting is at All Hallows Hill, near Tickhill, and 
a little over six miles south of Doncaster. In its deepest part the clay 
exceeds 20 feet in thickness, the base not being exposed. ‘The boulders 
are Permian limestone up to 12 cubic feet. There are grits, gannisters, 
and Carboniferous limestones, the latter ranging up to 2-foot cubes. 
Some of the Carboniferous limestone blocks contain Productus cora, 
P. scabriculo-costatus, P. longispinus, and Pterinopecten. There are a 
few Lake District boulders. The stones are sub-angular and are well 
scratched. Boulders reported are as follows: All Hallows Hill, near 
Tickhill—Lake District volcanic ash, 1-foot cube. 
Kirk Sandal.— From trench on South Yorkshire Junction Railway, 
13 mile south of Kirk Sandal Church—Lake District volcanic ash 
18 x 13 x 13 inches. 
This is 3 miles N.E of the well-known patch of boulder clay at 
Balby.
