tlie same appearance as that of the specimens we have just de- 
scribed_, the cells are not always filled with clay^ in many cases 
they are partially or quite empty, and therefore we have no dif- 
ficulty in tracing the affinity between them. 
The question of interest connected with these remains is that 
of their origin. The labours of the geologist having traced the 
occurrence or absence of particular species in or from particular 
strata, we are now led from the discernment of the species to the 
identification of their parent bed. The ammonites perarmatus 
is essensially ooHtic : the A. obtusus, on the contrary, liassic, 
whilst the septaria which accompanies them is abundant in the 
Kimmeridge clay of the district to the north-east of Kadwell. 
This diversity of origin, perplexing as it might appear at first 
sight, is the better means placed at our disposal, for the solution 
of the question before us. The di'ift must have occurred from 
the north — the remains of ammonites in this di'ifted gravel are 
identical with those of the Yorkshire oolite and lias, and the lo- 
cahty of the septaria we have before stated to be equally clear — • 
added to these the general direction of the diluvium in this dis- 
trict is a further proof of the correctness of our supposition.
