EXHIBITS: 
1. Professor Sir Edgeworth David exhibited specimens of 
spore-bearing chert from a horizon in the Lower 
Marine Stage of the Permian (Permo-Carboniferous) 
on the EKelah Road, Portion 29, Parish Middlehope, 
County Durham. The spores are in a very perfect 
state of preservation, the cuticle retaining the original 
structure. It is suggested that the surrounding hills 
of Carboniferous sediments and eruptives—a continua- 
tion of the Hudson’s Peak area—during the time of 
Lower Marine sedimentation supported a coniferous 
(Araucarian) forest the transported spores of which 
became imbedded and preserved in the fine grained 
sediments. 
2. Professor W. E. Cooke, Government Astronomer, a 
record of the Chilian Karthquake of the 11th November, 
1922.
