66 SKETCH OF THE LIFE AND CHARACTER 
the botanical department of Natural History, and 
from the habits of patient and accurate investiga- 
tion which he had exercised in cultivating it. In 
1838 he communicated to the Geological Society 
through Mr. Murchison, some ‘‘ Notes on a small 
patch of Silurian rocks to the West of Abergele, 
on the northern coast of Denbighshire,” which he 
had visited in the summer of the preceding year.* 
This paper contains a brief description of the dip, 
appearance and contents of successive strata, and 
betrays in a few simple touches the deep feeling 
of its author, amidst the minutest scientific obser- 
vation, for the beautiful of natural scenery. Two 
years afterwards at the request of Mr. Murchison, 
he undertook an examination of the Silurian rocks 
in the vale of Llangollen, with a view to ascertain 
the boundary of the Silurian and Cambrian sys- 
tems in Montgomeryshire and Denbighshire. 
This boundary from the dislocated state of the 
country, he was wholly unable to trace; but he 
exhibited in his paper some new geological fea- 
tures which had come to light in the course of his 
researches.
