The basin of red marl in which this lacustrine deposit is formed 
is very limited, only a few hundred yards long from east to west, and 
not so much from north to south ; the black ossiferous and shelly 
marl appears by Mr. Harcourt’s borings to be in one place only about 
50 or 60 yards across in the direction from north to south. About 
a quarter of a mile to the east is another marl deposit, covered by 
five or six feet of chalk and flint gravel ; half a mile further in 
the same direction is another consisting of a stronger blue clay, in 
which much undecomposed shale may be observed, enveloping in its 
upper part boulders of the chalk, blue oolite, and lias of the neighbour- 
ing hills. 
Condition of the bones. Among the numerous specimens of bones 
very few shewed the least mark of mechanical attrition, or chemical 
decomposition ; in general they were perfectly preserved, and many 
of them entire ; such as were broken shewed uninjured surfaces and 
angles of fracture. On the ends and edges of two of the broken 
bones, there was a high polish ; a peculiar corrosion into little pits 
was observed on one or two fragments : the epiphyses of the vertebrae 
of the elephant (it being a young individual) were found nearly in 
their relative place, and the same remark applies to the metatarsal 
and phalangal bones of the horse, and to the leg bones of the wolf. 
Upon the whole nothing can be more certain than that the bones in 
the black marl were inhumed only a very small distance from the 
place where the animals died, that they had not been subject to the 
ravenous jaws of hyaenas, nor been transported from any earlier deposit. 
The following species of animals were recognised. 
Remains of Quadiujpeds. These were found both in the black marl and in the 
superior marly gravel deposits. 
Elephant (Elephas primigenius Blum). Tusk, teeth, humerus, 
and vertebra;. 
Rhinoceros tichorhinus ... Teeth, tibiae, rib ? 
Bos urus antiquus — Cranium and horns, teeth, vertebrae, bones of the legs 
and feet. Parts of two individuals were recognized.
