sand and oolitic granules. The junction between the White 
Limestone and the “Forest Marble” was well shown in the 
quarries at Tiltup End, and the upper bed of White Limestone, 
and a thin band in one of the quarries lying upon the Lime- 
_ stone, contained a large assemblage of fossils, chiefly of the 
_ genus Nerinea. The shells, specimens of which were exhibited, 
were exceptionally large. Corals were also found in the bed, 
and small round concretionary lumps covered with Bryozoa. 
From the discovery of this assemblage of fossils, and a similar 
one recorded by Dr Lycrrr on the same horizon, but on the 
east side of Minchinhampton, Mr Wircue.t thought there was 
_ evidence of a pause in the Oolitic deposits, and a change of 
level and of marine conditions between the Limestone period ° 
and that of the overlying “ Forest Marble.” 
THE SECOND WINTER MEETING 
_ of the Club for the season was held in the Lecture Theatre of the 
SCIENCE SCHOOL IN GLOUCESTER, 
on Tuesday, the 3rd of February, 1885, when a paper was read 
by Enwarp WeruereD, F.G.S., on the “ Structure of Carbon- 
iferous and Cretaceous Coal.” Much has been written on the 
subject of the structure of coal since De Luc, in the year 
17935, first contended that it was the product of vegetation 
which grew on the spots where the seams now rest. An 
important addition to our knowledge of the question was made 
by Sa Woi14m Logan, in 1841, who pointed out that under 
every seam of coal there was.a stratum of clay, known as the 
was always to be found, and subsequent discovery proving it to 
be the root of Lepidendroid plants generally, led up to the idea 
that coal was formed mainly from the submergence of forests of 
Lepidodendra. Inthe year 1870 Professor Huxuey modified this 
view by attributing the formation to accumulations of spores of 
that class of vegetation, the wood forming the mineral charcoal. 
Among those who advocated the submerged forest theory were
