The following specifications, proposed by a sub-committee of the American Society for Testing Materials, are still to be adopted and subsequently submitted to the International Association for Testing Materials. Standard Specifications for Pig-Iron and Castings. I. Analysis.—It is recommended that all purchases be made by analysis. II. Sampling.—In contracts where pig-iron is sold by chemical analysis, each carload, or its equivalent, shall be considered as a unit. At least one pig shall be selected at random from each two tons of every carload, and so as to fairly represent it. Drillings shall be taken so as to fairly represent the fracture surface of each pig, and the sample analyzed shall consist of an equal quantity of drillings from each pig, well mixed and ground before analysis. III. Allowances and Penalties.—III all contracts, in the absence of a definite understanding to the contrary, a variation of 10 per cent. of silicon, either way, and of .01 in sulphur above the standard is allowed. A deficiency of over 10 per cent. in the silicon, up to 20 per cent., and a further increase in sulphur up to .01 over the above allowance subjects the shipment to a penalty of 1 per cent. in the price for each element so affected. IV. Base Analysis OF Grades. —In the absence of specifications the following numbers, known to the trade, shall represent the appended analyses for standard grades of foundry pig-iron, irrespective of the fracture, and subject to allowances and penalties as above. Silicon Sulphur Grade. Per Cent. Per Cent. No. 1,...2.75 0.035 No. 2,.2.25 0.045 No. 3,........1.75 0.055 No. 4,.1.25 0.066 Cast-Iron Pipe and Special Castings. I. Description of Pipes.—The pipes shall be made with hub- and spigot-joints, and shall accurately conform to the dimensions given in Tables Nos. I. and 11. They shall be straight and shall be true circles in section, with their inner and outer surfaces concentric, and shall be of the specified dimeneions in outside diameter. They shall be at least 12 feet in length, exclusive of socket. For pipes of each size from 4-inch to 24-inch, inclusive, there shall be two standards of outside diameter, and for pipes from 30-inch to 60-inch, inclusive, there shall be four standards of outside diameter, as shown by Table No. 11.

The discussion on my paper entitled "Experiments with a Straight or No-bosh Furnace," read at the Philadelphia Meeting, September, 1884 (Transactions, vol. xiii., p. 489), suggests the propriety of slipplementing it with another, giving my views as to the cause of the failure, which was so decided as to create surprise among furnace men. As then stated, the Chester (8. J.) furnace, which had been 60 feet high, and 13 feet in diameter at the bosh, was altered to an 8-foot bosh, with a 7-foot hearth, 7-foot stock-line, and 4-foot bell,
