Specimen No. 3. was obtained from the furnace in Wood- 

 stock, N. B., and was reduced from a Manganesian red Hsema- 

 tite. The metal is hard, white, and granular-crystalline, with a 

 few intersecting plates of crystals. 



Its specific gravity is 7.330. 



On analysis the following results were obtained.

Analysis of the ore from which this iron was reduced. 

 The following results were obtained by Mr. Richard Crossley, 

 who analyzed the Haematite from Woodstock last year.

52.50 of per Oxide of Iron contains 36.39 of metallic Iron. 

 18.90 Manganeso-manganic oxide contains 13.62 of Manganese. 

 Hence, 36^39+ 13.62 = 50.01, and 



50.01 : 13.62 : : 100 : 27.23 Manganese. 



It appears, therefore, from my analysis, that more than half 

 the oxide of Manganese in the ore was reduced and entered 

 into an alloy with the Iron. 



These alloys are not generally understood by Iron masters, 

 founders, and refiners, and are frequently mistaken for iron con- 

 taining sulphur or phosphorus. 



Manganesian Iron is unfit for foundery purposes, but makes 

 the best kinds of malleable or wrought iron when refined in the 

 forge or puddling furnace. It " comes to nature " slowly, and 

 hence makes a good mixture with iron* rich in carbon, which
