opened in a field near Bridlington by Mr. E. Tindall, and others in 
land belonging- to Yarborougli Lloyd, Esq., which resulted in the dis- 
covery of bronze fibulae which Mr. Wright said were undoubtedly 
Roman. One of the tumuli was nearly forty yards in circumference ; 
it was penetrated from the surface in the centre, and beneath a 
quantity of boulder or cobble stones there were found five rows of 
horizontal stones radiating from a centre; at the extremity of two of 
these an urn was found. The urns were found in hollows of the chalk 
made for their reception, and above them was extended a slab of 
stone ; they contained a pasty matter, some pieces of leather, and 
a quantity of hair. An attempt was made, under the direction of 
Lord Londesborough, to open the Willey-How, a mile from Wold 
Newton, but after making a considerable trench it was abandoned. 
Mr. H. C. Sorby, F.R.S., read a paper on the so-called crag deposit 
at Bridlington, and the miscroscopic fossils occurring in it. The beds 
were near the base of the cliff, a quarter of a mile north of the pier. 
By washing the sandy clay in a fine sieve many foraminifera and 
entomostraca were easily picked out of the washed sand with a 
camel's hair brush. The specimens obtained were submitted to Mr. 
T. Rupert Jones, and he enumerated the following species : — 
Dentalium communis, Lagena striata, Polymorphina .lactea. Quin- 
queloculina seminulum, Robulina calcar, Truncatulina tuberculata, 
and also undetermined species of Biloculina, Guttulina, Nonionina, 
and Triloculina. The entomostraca belonged to two species, Cytheridea 
Sorbyana and C. concinna, neither of which had been previously 
known, either living or fossil. This list of fossils is interesting for 
comparison with the list prepared by the late Dr. Gwyn Jefi'eries, from 
specimens collected by Mr. Lamplugh. 
A valuable paper was contributed by Mr. Richard Carter, C.E., of 
Barnsley, on Colliery Ventilation, in which a broad view is taken of the 
duties of Coal-pit proprietors, in securing for their operatives not only a 
sufficient supply of fresh air for respiration, but also for the removal of 
gases given out by the coal and other strata in the mine, which, if not 
removed, are by tlnir presence and accumulation ever surrounding 
the entire operations with danger and deatli. Methods of ventilation 
are advocated by means of separate air shafts and other arrangements 
which have since come very generally into operation.
