of Worcester and Gloucester were now intersected by railways, and 
their cuttings and excavations opened wide fields for observation. 
Sir Roderick Murchison was completing his Silurian system, and had 
already entered into that contest with Sedgwick and Buckland which 
was so often and long fought in the meetings of Section C at the 
British Association. Strickland's residence being located within one 
great area of the disputed ground, and Cambria lying at no great 
distance, constant appeals were made to him to verify sections by 
Murchison, and he entered into the subject with ardour. The sub- 
ject would have been irresistible even if his previous studies had not 
prepared him for it, but previous to his Eastern expedition, geology 
occupied a foremost place in his mind, and finding so much more ex- 
tensive opportunities on his return, his interest became still more en- 
gTossing. Sir Roderick w^as entirely at variance with Dr. Buckland 
as to the supposed analogy, or rather the identity of the red sand- 
stone of Warwick with the Keuper. He looked upon the Gloucester- 
shire marls and subordinate bands of sandstone as Keuper, and the 
sandstones of Broomsgrove and Warwick as Bunter Sandstein, Buckland 
regarding the latter as Keuper. It was to work out these details that 
Strickland set himself, and being so well situated for observation his 
knowledge quickly became greater than that of Murchison, and the 
latter proposed that they should write a joint memoir on the subject 
for the Geological Society. In was in this paper that the first men- 
tion is made of fossil footprints in the English Keuper. Sti-ickland 
also communicated papers on the fluviatile drift of the Avon and of 
the Severn Valleys. His researches in this department were incor- 
porated in the Silurian system. He found many fossils during his 
investigations and his collection was rapidly assuming a somewhat 
portentious extent. 
In 1841, Strickland prepared a second edition of Murchison's 
Geology of Cheltenham, which is still a valuable guide to that inter- 
esting district. In 1837, accompanied by his father, he made a tour 
in Scotland, during which the material for his paper on some remark- 
able dykes of calcareous grit at Ethie, in Ross-shire, was collected. 
At the meeting of the British Association at Glasgow, in 1840, 
Strickland read his paper on the true method of discovering the
