    THIS memoir gives the results of an investigation into the character of the coals of South Wales. The collection of the material was begun in 1901, and the work has now so far progressed as to lead to an opinion as to the relative distribution of anthra-citic and bituminous coals, and as to the origin of the difference between them. The results published include not only the analyses made for the purposes of the investigation by Mr. Pollard, Mr. E. G. Radley and Mr. C. A. Seyler, but also ail previous trustworthy analyses of coal from recognisable seams. The total number of analyses is 203. In each case the particulars given include the local name of the seam, the colliery, the authority, the percentages of carbon, hydrogen, oxygen and nitrogen, the ratio of carbon to hydrogen, the percentages of volatile matter, and ash, the specific gravity, and the fuel ratio or the relation of fixed carbonaceous residue to volatile matter.
