    2 Prorisional Specification. Blunt's Diamond Coal Fuel. water to form of such materials a concrete mass. The relative pro¬ portions of such said materials which I use in composing such concrete mass are the following, viz*:— \ Parts by Weight. - 100 Bituminous coal - Anthracite coal Ground coke Ground cinders or bark River or sea sand Caustic lime Gypsum Coal tar Water - -_ M • ; t 150 90 90 - 10 20 10 30 - 500 10 1000 1 take such materials so proportioned to each other as regards their respective and relative quantities, and I intimately mix them together by grinding or other manipulation of like nature and intent, and I then mould, cast, or press the concrete material so prepared in particular forms or figures in equal and uniform blocks; and the forms which in practice I find best suited to such purpose are the following, viz1:— 1, the sphere, or spheroidal modifications of that solid; 2, the cylinder; 3, the prism; 4, the figure termed dodecrahedon,of 12equal pentagon faces; 5, the cube; & 6, parallelopipedon ; such forms being chosen by me because, when in action, they afford the most suitable insterstitial spaces amongst themselves to insure a due supply to and intermixture of atmospheric air with the gases produced in combustion, and thus support and increase it. The claim is for the - forms or figures of the blocks of fuel, as regards the interstitial spaces they afford in their arrangement when in use and action, and taken in combination with the composition herein¬ before stated. ;. , . 15 20 25 30 LONDON: Printed by George Edward Eyre and William Spottiswoode,
