done very economically, by this Society sending out sheets to the 
proprietors of engines, to be filled up with the particulars required. 
They might or might not fill them up as they pleased, but great good 
would arise if they did so. 
Mr. WilHam West had a strong impression that societies like 
this might obtain information where individuals failed. He was 
desirous to ascertain the proportion of fuel consumed to the quantity 
of water evaporated from the boiler, and this information he had 
sought in vain. If the Society should take up the enquiries suggested 
by Mr. Morton, he hoped this question would be included. 
Mr. T. W. Embleton spoke of the importance of Mr. West's 
suggestion. At present nothing was known in Yorkshire as to the 
quantity of coal consumed by engines. After some remarks from 
Mr. Marsh and Mr. Hartop, the meeting separated for dinner at 
three o'clock at Scarborough's Hotel. At seven o'clock the mem- 
bers re-assembled, and the Rev. Dr. Hook resumed the chair. Papers 
were read by Mr. Charles Morton on Safety Lamps, and by Mr. T. W. 
Embleton on the succession of the strata in the Northern Yorkshire 
Coal-field. In connection with the former Mr. W. Sykes Ward, 
of Leeds, introduced and explained an oxy-hydrogen lamp, which 
he stated would burn without communication with atmospheric air. 
Mr. Embleton confined his paper to a consideration of the order 
of the various seams of coal found in the townships of Whitwood, 
Methley, Stanley, Wrenthorpe, Loft house. Roth well, Ardsley, Middle- 
ton, and Beeston. It would be of great importance to the Society 
if the order of the seams of coal were determined in each district, 
and it was the only sure foundation for comparison with distant 
parts of the coal-field. It was only by a careful collection of shaft 
sections that many important questions in local geology could be 
satisfactorily cleared up. As for instance the thinning or thickening 
of certain seams in particular directions ; the existence of seams 
at one colliery which were not found in an adjoining one ; the origin 
of coal itself. Comparisons of such sections would set at rest the 
long agitated discussion as to the origin of cannel coal, which, as 
asserted by many, is only to be found in the vicinity of throws or 
dykes. Professor Johnston was of opinion that it was the result of a
