and it presents in Lincolnshire a fine development at its base of 
the Red Chalk which characterises the country north of the 
Wash. Each division of the chalk is represented in Lincolnshire, 
but that had only become known recently. Mr. Hill, of the 
Geological Survey, recently found L^pper Chalk fossils, and Mr. 
Burnett, a native of Lincolnshire now resident in Leeds, had made 
a very patient search, and had found a persistent band of Upper 
Chalk running from a place north of Louth to the Humber. He 
had found a characteristic Micraster and Holaster. [We may 
add that some of the visitors found the Micraster at the Boswell 
pit.] The Lower Chalk is thin, and includes a bed of pink chplk, 
and tlie Red Chalk at the base is comparable to that of Hun- 
stanton and Speeton. The Neocomian is even more developed 
than in the section at Speeton. It has well marked lithological 
divisions, but had been much mangled by glacial agency. The 
Spilsby Sandstone passes abruptly from a loose, incoherent sand 
to hard sandstone used for building purposes, and Professor 
Kendall's explanation was that the former had been largely 
decalcified. The Spilsby Sandstone forms a well-defined stratum, 
particularly noticeable in the neighbourhood of Somersby, the 
birthplace of Tennyson. There is a particularly fine section of the 
Claxby ironstone, and a splendid suite of fossils is yielded by it. 
This would be seen on Monday, and also the Tealby Clay, which 
is visible in a brickyard a few yards from the railway line. Above 
this comes the Carstone, and the pebbles in this and the Spilsby 
Sandstone are of very great interest. What struck him as most 
characteristic of these two divisions were small and generally 
angular pebbles, of which he said he did not know of any British 
rock at present exposed which could be regarded as a possible 
source. They could not have travelled far, and their form 
suggested that they were derived from some coast-line exposed 
in Neocomian times. The subject was well worthy of investiga- 
tion, and he was inclined to think that in Palaeozoic rocks under- 
lying East Anglia we should find their source. He had seen rocks 
called phthanite in Belgium which were similar. The undulation 
at Louth is probably based upon an ancient hill-forming fold, 
which forms the eastern boundary of the great coalfield from 
Derby to Nottingham. He had recently given reasons for
