405 Harrison, Ainslie, & Co., Newland Furnace,Ukerston —Producers.
Haematite iron ore, from Lindal Moor, in Furness,containing metallic iron, 66*47 percent.; oxygen, 28*50percent.; silica, 3*43 per cent.; zinc, *71; moisture andloss, *89.
Charcoal pig-iron and furnace cinder, from Newland,Backbarrow, Duddon, and Lorn furnaces, said to be theonly charcoal furnaces in Britain .
406 Farnley Company —Producer.
Specimens of coal, coke, and iron-stone.
407 Dickinson, Thomas Friend, Newcastle-upon-Tyne—Producer.
Specimen of haematite, or kidney ore, exported fromBalcarry Bay; used to mix with poorer iron-stone.
[These peroxides of iron vary in the quantities of ironthey contain. Where they are crystalline they are usuallyfound to consist—of iron, 70, and oxygen, 30. The un-crystallized varieties are generally not so rich, yieldingoxygen, 30*66, and iron, 60*34. These ores afford a con-siderable portion of the iron manufactured in differentcountries; they are also, when ground, employed forpolishing metals, and used as a colouring material.—R.H.]
408 Moore, Joseph, M.D., 10 Saville Row —Proprietor.
Iron ore, from the surface of the Arigna mines, on thewestern side of lake Allen, in the county of Roscommon .Calcined iron ore.
Limestone rock. Fire-clay, used for making bricks forkilns and furnaces. Fire-bricks, made from the same.
Moulding sand.
Specimens of coal found in the locality.
Peat turf, soft and hard. Charred peat for smelting.—Peat, called in Ireland turf, is used as fuel for domesticpurposes; it may be used with advantage for smeltingthe iron ore, having all the effect of wood, and, whencharred, of charcoal, which imparts to the iron the pro-perties so highly prized in metal: prepared in wood fur-naces.
Bar of iron, from the ore of Arigna. Bar of steel,converted from the same.
Crystallized rock, having a fine fracture, being thesurface rock of the district.

[The river Arigna divides the Connaught coal-field intotwo parts.' The southern division consists of a great moun-tain ridge called Brahlieve, at the base of which are theArigna iron-works. The rocks within this district aresimilar to those of other coal-fields, consisting of sand-stone, shale, clay-ironstone, and fine fire-clay. The shale,which varies in thickness from 300 to 600 feet, rests onlimestone rock, and is remarkable for its rich beds of iron-stone.
Sir Robert Kane has given the following analysis of the
clay-ironstone from Arigna:
Protoxide of iron
54-42
Lime
2-23
Magnesia
2-02
Alumina
1-43
Clay .
8-65
Carbonic acid
31-25
The mean of many analyses gives 40 percent, of metalliciron, as the average produce of the iron ore of this district.Sir John Guest reported on the Arigna mines in 1804, andstated the cost of production to be as follows:—

Hr. Griffith, in his report on the Connaught coal-field,estimates the cost of a ton of iron, produced in thislocality, at only 3 1. 2s. 5d. The real working cost appears,however, to be somewhat between the two. These state-ments are important, as directing attention to a very in-teresting iron-producing locality, which does not appearto have received the notice it merits.—R. H.]
409 Schneider, Henry William, Ulverstone —Producer and Manufacturer.
Red haematite iron ore.
Pig-iron, from Scotland , used therewith.
Bar-iron, made from the two combined.
Blister-steel, made from a mixture of iron ore andScotch pig-iron.
Cast-steel, made direct from the iron ore and pig-iron,without being first converted into blister steel.
Shear steel, made direct from the iron ore'and pig-iron, without being first converted into blister steel.
410 Solly &Co., leabrook Iron and Steel Works,Tipton, Staffordshire —Manufacturers.
Specimens of billet and bar-iron, made by the ex-hibitors.
Specimens of the finest wire, and of all kinds of steelmade from the exhibitors’ iron: as blistered, spring,double shear, and cast steel.
Specimens of saws, files, and a variety of other tools,and of fine cutlery, including a carriage-spring, allmade from the steel manufactured from the exhibitors’iron.
411 Bird, William, & Co., 5 Martin's Lane, CannonSt?'eet, City —Proprietors.
