Proceedings. oo 
Ordinary Meeting, Nov. 20th, 1878. 
ALFRED CARPENTER, Esgq., M.D., President, in the Chair. 
The minutes of the last meeting having been read and con- 
firmed, Mr. J. Truman, Mr. Walter Cooper, and Mr. Samuel 
Palmer were balloted for and elected. 
The PreEsIpDENT announced that Mr. Howard Martin had 
retired from the committee of the Club, in consequence of his 
many other engagements, and that the committee had decided 
not to fill up the place thus left in the committee, but to lecve 
‘it to be filled up by the General Meeting in January. He also 
announced that the paper which was read by Mr. George 
Corden on “ The Meteorology of Croydon” on April 17th last, 
had been separately printed, and that a copy of it would be 
forwarded to every member of the Club. 
Mr. J. CuIsHoLM read a paper ‘‘ On a Geological Section in 
Park Hill Rise.” Mr. Chisholm first referred to the labours 
of Professor Prestwich, who, about 30 years ago, clearly 
demonstrated the Lower London Tertiaries, which occur 
between the London clay and the chalk formations, to be 
separable into three great divisions, which now go by the 
names of the Oldhaven, the Woolwich and Reading, and the 
Thanet beds respectively. Their position at Park Hill was 
illustrated by a diagram enlarged from a drawing in a paper 
by Professor Prestwich, in Vol. 10 of the Quarterly Journal of 
the Geological Society, p. gg, and their general structure and 
distribution commented on. Attention was next directed to a 
section taken from a pit ina garden at the top of Park Hill-rise. 
The various strata uncovered were explained, and a number of 
fossils, ostrea bellovacina, calyptroea trochiformis, cyrena, 
&c., found in some of the beds were exhibited. The point of 
interest in this section was the apparent overlying of the Old- 
haven pebbles by the Woolwich and Reading beds, the second 
member of the Lower Tertiaries, and Mr. Chisholm brought 
forward several reasons for supposing this to be really the case. 
He also stated that he had received a letter from Mr. Whitaker, 
the well-known member of the Survey, in which it was 
suggested that there might be a “ reversed fault”’ at this spot. 
The result of a number of other openings in the neighbourhood 
was then given; among others that of a boring 20-ft. deep 
made by Mr. Baldwin Latham in his garden for the purpose of 
making researches into the underground temperature. Asa 
general conclusion, Mr. Chisholm believed that the bed of Old- 
haven pebbles would be found to cover a considerable part of 
the northerly slope of Park Hill, and the plastic clay of the 
Woolwich series continued along the top of the hill between
