210 THE GEOLOGICAL SURVEY 
to take rooms for some time at 3 Great Ryder Street, near the 
temporary quarters of the Survey, and Jermyn Street, where 
the Museum of Practical Geology was being built for its 
accommodation. 
Of his occupations at this time he writes to Dawson Turner 
(April 31, 1846): 
At present I am worked rather hard, having to go into 
town every day to study fossil Botany, until the proposed 
Museum is built in Piccadilly. The apartments now filling 
up are thus only temporary, and are granted by the Dean 
of Westminster in the shape of servants' rooms over his 
stable. Though small, they are neat and quite suitable, 
looking into Dean's Yard and entering by a respectable 
little doorway on the courtyard. The Dean is very civil 
and busy in his improvements of the badly dilapidated 
yard ; he is giving us a fine lamp opposite our door and 
otherwise takes a gi'eat interest in all that is going on. * 
The great difference between my father's and all other 
Government employments evidently consists in his not 
being supphed with tools, as I am in my humble capacity, 
and as Brown and all other public officers whose real income 
is thus a'p'parently not so good as my father's ; but it is 
apparently only, for if they had to purchase their books 
and plants they would all be rumed. 
In May and June his work took him into South Wales, to 
examine the coal-beds for fossil plants in situ ; in August and 
September to the Bristol coalfield. In South Wales, where 
• De la Beche appears very ^pleased with what I have done,' 
his headquarters were near Swansea, with his grandfather's 
old friends the Dillwyns,^ whom he delighted by discovering 
the ■ Lesser Wintergreen (Pyrola minor), which had not been 
found in the neighbourhood before. Their son, Lewis Dillwyn, 
1 Lewis Weston Dillwyn (1778-1855), botanist, conchologist, and potter, 
was born at Ipswich, within touch of the Turner-Hooker circle. It was not 
till 1803 that he moved to Swansea to take charge of the pottery bought by 
his father. He had already begun his Natural History of British Confervae, 
and collaborated with Dawson Turner in the Botanisfs Guide through England 
and Wales, 1805. At Swansea he wrote on the local flora and fauna and the 
history of 'the city, as well as sharing in civic affairs. He was M.P. from 
1832-7.
