This is specially interesting the University of Upsala, who in 1781 showed that steel from its relation to the calorimetric work of Lavoisier mainly differs from iron by containing about i per cent. and Laplace in 1780 and of Lavoisier in 1782, which led of plumbago, while iron does not.

Now that the importance of thermospecimens of iron is due to the presence of small quantities chemistry is beginning to be recognized in relation to of impurity, and that the properties of iron do not vary, as industrial chemistry and metallurgy, it is to be hoped that he says, unless by chance the iron has gathered foreign Bergman's merits will be more fully considered.
