2. Grey pig, from the foundries of Zell, in Styria ,which enjoy a high reputation in the country.

3. White pig, from Eisenerz, in Styria , of differentqualities, from a finely-porous to a large laminated grain.

4. Specimens of steel, raw, forged, and cast.

5. Slags and cinder produced in the various prqcessesof smelting and preparing iron and steel, according tothe different ways in whicli the furnaces are worked.

G. Manufactured iron and steel. We may especiallynotice here the rails, of whose admirable quality theJury have satisfied themselves, and which afford a frac-ture remarkable for the homogeneity of the grain.

Topper, A., of Scheibbs, Lower Austria (411, p. 1031).Among the numerous objects sent by this exhibitor, wespecify particularly the hollow iron made at his foundry.The tubes are of excellent quality, and we learn from Pro-fessor Tinnier, the Austrian member of the Jury, thatM. Topper’s establishment enjoys a high reputation forthe manner in which it is directed, as well as for theexcellence of its produce. The work is carried on in avery economical maimer, and for 15 years the gases ofthe furnaces have been used economically in some of theoperations.

Prince Schwarzrnbkrg, of Murau, in Upper Styria (417, p. 1031). The foundry of Murau is intended forthe production of hard iron and natural steel: the exhi-bition made by the Prince is very complete, presentingan assortment of different qualities of iron and steel, aswell as cinder of all the operations. We may again statethat the steel is of admirable quality, enjoying a well-founded reputation in Austria and the Lombardo-VenetianKingdom.

Fischer, A., of St. iEgide, in Lower Austria (420.)Brown spathic iron ores; white, grey, and speckled pig,obtained from charcoal fuel; bar iron of different kinds;steel, raw and forged ; iron wire, rolled and drawn. Allthese are of excellent quality. The mechanical arrange-ments in M. Fischer’s works are remarkable for theirfinish, and for the facility with which they admit of thedifferent operations being performed.

The Wollersdorff Tin-pi.atk Works, Lower Aus-tria (423, p. 1031). This establishment, intended for themanufacture of tin-plate, is of modern construction, andthe proprietors have availed themselves of the mostrecent mechanical improvements and contrivances. Theproducts are not inferior in quality in any respect tothe best tin-plate manufactures in England and Belgium.This is considered to be the largest establishment of itskind in the country.

The different iron-foundries, whose various products wehave here mentioned in a very summary way, have eachobtained Prize Medals; and before proceeding to give afew details concerning those other establishments of thesame nature which have beeu adjudged Honourable Men-tion, we desire to notice one more to which the Jury haveawarded a Prize Medal. It belongs to J. B. Eggcr,* ofVillach, in Carinthia , and it has for its object the manu-facture of sheet lead and lead tubing. The products exhi-bited (435, p. 1032) are tubes of various bore and dif-ferent dimensions, one of them being 1800 feet long.Notwithstanding this great length, the bore is perfectlycylindrical, and the thickness is the same throughout.

The Jury have awarded Honourable Mention to thefollowing Exhibitors:—

The Community of Radmeister, at Vorderaberg,Styria (400, p. 1030). A collection of ores, pig iron,slags, iron, and steel. The furnaces, which have beeurecently enlarged, are worked with hot blast.

* This Exhibitor receives a Prize Medal in Class XXU.,in whose Award List his name appears.—I. \Y.

1 1031). In these works the puddling and reheating of theiron are carried on by the aid of reverberatory furnaces,i supplied with the charcoal of brushwood, otherwise of; no value. This important modification, which has intro-, duced a great economy in the manufacture of the iron, isijot alluded to in the collection of products from the, Demo foundry.

Fischer, Ik, of Traisen, Lower Austria (421, p. 1031).These works chiefly manufacture cast steel; their pro-ducts are carried into all parts of Germany .
