THE GEOLOGIST. 
If I miglit be permitted to give advice to any member of our 
Association who should hereafter visit the place, it would be this — 
that it would be well for him to carry away moderate sized boulders 
entire, rather than to break them on the spot. The fossils will best 
be developed at leisure. The material is so hai'd, and the fossils so 
brittle (especially the beleranites and serpvilee), that imperfect specimens 
only will result from the quick and rough treatment of the hammer. 
The "find" will not produce any very great variety, only numbers; 
terebratula3, serpulse, and belemnites will be all that will be obtained. 
Having now procured specimens, we had better walk southward 
along the shore ; after a short time will be seen a fine perpendicular 
section of this particular stratum ; we shall notice it is bounded on 
the one side by the White Chalk, to which it is parallel ; on the 
other by the Speeton clay, which is not conformable to it, that is, not 
parallel. 
The thickness of the bed of the Red Chalk is at this place, as I said 
just now, about thirty feet. First of all, taking it in descending 
order, that is to say, having reached its limit at the White Chalk, 
and retracing our steps in the direction of Filey, we notice about 
twelve feet of red matter containing serpulee, and we note that the 
upper portion of this division is much filled with greyish nodules, 
showing that the change from the White Chalk to the Red is gradual. 
Next comes a bed of about seven feet thick, of darkish White Chalk ; 
and finally, another bed of about twelve feet thick, of bright Red 
Chalk, containing belemnites and terebratulee. The whole is followed 
by the Speeton clay, of which a short and accurate account will be 
found in No. 13 of The Geologist magazine. The line of division 
between these two being well marked by runs of water, which are 
caused by the percolation through the chalk being stopped by the 
impervious clay. ^ 
The Speeton clay is singular in some of its characteristics. At its 
upper portion, in contact with the Red Chalk, it contains fossils belong- 
ing to the Neocomian or Greensand era, whilst at the lower part there 
are the representatives of the Kimmeridge clay. And thus it would 
appear to be one of those peculiar formations which have resulted 
from a number of beds thinning out, and becoming absorbed into 
each otlier. Three of the well-marked fossils of the Speeton clay may
