3. ‘On the Discovery of Flint Implements in the Drift at Milford 
Hill, Salisbury.” By Dr. H. P. Blackmore. Communicated by 
John Evans, Esq., F.R.S., F.G.S.—Since the discovery of Flint 
Implements in the higher-level gravel at Fisherton on the west of 
Salisbury, a large number of very excellent weapons have been 
obtained from the drift-gravel of Milford Hill. This deposit is 
of the same age as the Fisherton beds; but it is situated on the 
opposite side of the Avon, immediately to the east of Salisbury. 
Dr. Blackmore described the materials composing the gravel of 
Milford Hill, and discussed the nature and power of the forces 
which had brought them together. He then described the position, 
thickness, and physical relations of the deposit, stating that the 
gravel is from 10 to 12 feet thick on the top of the hill, becoming 
thinner and gradually dying away on the sides. The hill itself is 
quite isolated, being separated from the surrounding higher land by 
river-valleys ; its highest point is about 100 feet above the present 
level of the rivers. In making a cutting on the south-eastern side 
of the hill, a bed of sand containing four species of land-shells was 
discovered near the base of the gravel. No other fossils have been 
found in the deposit, with the exception of a single tooth of a species 
of Equus. Dr. Blackmore concluded by describing the implements 
themselves, which nearly all belong to the long-pointed type, thus 
confirming the opinion of Mr. Evans, that this form is mainly 
characteristic of the higher-level gravels. 
II. March 8, 1865.—W. J. Hamilton, Esq., President, in the 
chair.—1l. ‘On the Echinodermata from the South-east Coast of 
Arabia, and from Bagh on the Nerbudda, India.’ By P. Martin 
Duncan, M.B., Sec. G.S.—Dr. Duncan described eight species of 
fossil Echinoderms, only one of which was new, from Ras Fartak 
and Ras Sharwén on the south-east coast of Arabia, and four from 
Bagh on the Nerbudda. He also mentioned five determinable 
species of other classes from each locality. Of these fossils, Hemi- 
aster similis, D’Orb., and Pecten quadricostatus, Sow., were alone 
common to the two localities ; but, with the exception of the new 
Hehinoderm Cottaldia Carteri (Duncan), all the species occur in 
European Cretaceous rocks. He considered the fossils from the two 
localities to belong to the same period, and discussed the question of 
the correlation of the deposits containing them with those of Europe, 
coming to the conclusion that they were most probably of Ceno- 
manian rather than Neocomian age, and of later date than the 
Pondicherry series : but he also remarked that it is impossible to 
determine their exact contemporaneity, the vertical range of many 
of the species being so great, and the parallelism of the allied Euro- 
pean Cretaceous beds not exact. In conclusion, Dr. Duncan discussed 
‘several questions arising out of a comparison of fossils from distant 
localities, especially the specific identity of similar specimens occur- 
ring in different formations, or in distant regions ; also the variability 
of certain species, and the idea of ‘ homotaxis.’
