Committee for Geology, &c. 
The Committee recommend,—That Mr. John Taylor be re¬ 
quested to prepare for the next Meeting, a Report on the state 
of our knowledge of Mineral Veins. 
That the attention of Geologists be invited to the Faults or 
Dykes in the carboniferous rocks in Flintshire, with a view to 
ascertain whether some remarkable differences in their charac¬ 
ter may not be observed, as compared with that of veins and 
dykes in other districts. 
That the attention of Geologists be invited to those coal 
districts in the midland counties of England, where the Carbo¬ 
niferous Limestone and Old Red Sandstone being deficient, 
the coal measures rest immediately on the Grauwacke and 
Transition rocks;—with a view to discover whether any circum¬ 
stances connected with the physical structure of that part of the 
island can be stated, explanatory of the local absence of the two 
great formations above mentioned. 
That Mr. John Taylor be requested to collect detailed sec¬ 
tions of the Carboniferous series of Flintshire, with a view to a 
comparison with the same series in other parts of England 
with a view also of ascertaining the circumstances under which 
the Mountain Limestone is developed, after its suppression in 
certain coal-fields in the central parts of England. 
That sections and plans should also be collected of the Coal- 
Acetate of Barytes .. Ba+Acetic
