The Coals Of South Wales With Special Reference To The Origin And Distribution Of Anthracite PDF Download

Excerpt from The Coals of South Wales: With Special Reference to the Origin and Distribution of Anthracite IN the preparation of a second edition of this Memoir, Dr. Pollard, who retired from the Geological Survey in 1913, has been so kind as to give his services. A large number of new analyses has been added, partly of samples collected by the Survey during a recent revision of some of the maps, and partly through the kindness of Mr. C. A. Seyler. The actual number of additional analyses is 118, and of these 15 were made by Mr. Radley under the supervision of Dr. Pollard before his retirement, 46 were of samples collected by the Survey but analysed by the Government Laboratory and 57 were by Mr. Seyler. The methods of analysis employed were in all cases such as to give strictly comparable results. For facilities in collecting the new samples we are indebted to a large. Number of Colliery Proprietors and Officials, who in all cases cordially gave their assistance to our collectors. The same conditions as regards methods of collecting and the publication of the names of the collieries were Observed as in 1908.
