670 REY. 0. FISHER ON A MAMMALIFEROUS 
49. On a Maumatirerovus Deposit at Barrineton, near CAMBRIDGE. 
By Rev. O. Fisuer, M.A., F.G.S. (Read June 11, 1879.) 
Dourive the latter part of the summer of 1878 I heard from Mr. 
Griffith, of Christ’s College, Cambridge, that large bones were being 
met with in a “coprolite-pit” at Barrington, on land belonging to 
Trinity College. Accompanying him there, we found the workmen 
had reserved for him fragments of three canines of a Hippopotamus, 
with some of the molars, a tooth of Rhinoceros, and other specimens. 
Further discoveries were made; and in September, when the work 
had been discontinued for harvest, | went there with two friends, 
and, armed with no tool better than a knife, obtained an excellent 
specimen of an incisor of the Hippopotamus. Upon this I advised 
Mr. Keeping, of the Woodwardian Museum, to get permission to 
commence a regular search for fossils, which, term not having com- 
menced, and the Professor being in the country, he took upon him- 
self the responsibility of doing, and through the kindness of Messrs. 
Smith and Badcock, the lessees of the coprolite-works, began a 
systematic exploration of the deposit. This was carried on after the 
Professor’s return under his authority, and has been rewarded with 
great success. 
The locality is easily recognized upon the Ordnance Map as being 
just south of where the final n in the word Barrington is printed. It 
is on the edge of a nearly level tract of ground at the foot of the hill 
between Haslingfield and Barrington, at an elevation of about 20 
feet above the alluvial ground of the present stream of the Rhee. 
This tract of ground does not, hcwever, form quite a flat terrace, 
but falls again very gradually northward towards the small streamlet, 
which, lower down, is crossed by the road near the church. The 
streamlet is not marked in the Ordnance Map, which wrongly repre- 
sents the slope of the hill as extending to the lane which leads to 
the pit. The pit is nearly on the highest part of this tract; and 
consequently the bone-bearing deposit does not belong to the existing 
drainage-system, but, though at only a small altitude, may be still 
considered a high-level gravel. 
The exposed section at present extends from north to south about 
70 yards. The “coprolites” have been obtained in the deepest part 
at 22 feet. The section presents a superficial covering of soil and 
fine gravelly “ trail,” which, in the southern half, rests immediately 
on disintegrated chalk-marl; but towards the centre of the pit a 
thin bed of coarse gravelly silt with large pebbles comes in (see fig., 
p- 671), dipping slightly towards the north, and when it has de- 
scended to about 8 feet from the surface it rather suddenly expands 
downwards, forming a mass of grey gravelly silt, with many large 
stones towards the bottom, some of which may weigh from twelve 
to sixteen pounds. Above the stony bed the material is without 
large pebbles, otherwise of a similar character. Throughout these
