CORRELATION OF THE BOURNEMOUTH BEDS. 223 
quite at the base of the cliff deserves especial notice, as it is literally 
crowded with seeds and fruit, supposed of Hightea and Cucumites, 
and more rarely fruits of Petrophiloides. The patch is situated 
between the extremities of two unconformable sandy clay-beds. 
[So local, however, are these seeds that within the last year a 
shift of a small streamlet 2 or 3 yards to the east has caused them 
but rarely to be washed out.| They appear at the time of deposition 
to have been caught in an eddy, and are mixed with stems and 
leaves, the latter, although they cannot be worked out, being so 
perfect when weathered out by spray as to seem like freshly decayed 
leaves blown on to the face of the cliff*. This new base-bed soon 
changes to sand of a white or ash-colour, full of lignitic grains and 
occasional slightly bored logs of wood, without fruits, but containing 
in one place an included mass of jet-black clay crowded with broken 
pinnee of Osmunda. ‘The section of the lower series is at this spot: 
—hlack clay at base, 8 feet; then white, drab and white sand with 
lignite, 44 feet; capped with a thin water-holding seam of clay. The 
upper series is unchanged. We now approach the point of final dis- 
appearance of the marine series of beds, which within about 100 yards 
gives place to beds of freshwater origin. Before their disappearance, 
which is due partly to the rise of lower beds and partly to their 
passage into the freshwater beds, they. become greatly disturbed, 
and have been much broken up and redeposited ; while the changes 
in their composition are so rapid that the most minute and careful 
examination is required to understand their sequence. They are 
mostly highly fossiliferous and of the greatest interest. Within 
less than 50 yards of the last section we have the following, in 
ascending order :—

* About fifteen distinct forms only are at present known from these beds, 
and they are mostly of small size. These fruits, although not rivalling in 
yariety and importance those from Sheppey, are nevertheless of the highest 
possible interest, as should their supposed identity with the latter be sustained, 
the fruits of Sheppey would assist in the determination of the Bournemouth 
leaves in an unlooked-for manner. If these fruits, which are above the horizon 
of the leaves, are identical with or even similar to those from the London Clay 
below, we have there the strongest reason to infer that the leaves lying between 
them were leaves belonging to the same groups of plants to which the fruits 
belonged, and grew on the same land. We may thus find in the Sheppey fruits
