Steel bars, formed of old files welded together, were 
pierced more quickly than iron, and presented the same 
phenomena. . , 
Cast iron, heated nearly to the me!ting point, underwent 0 
alteration, by the application of «ulphurto its surface. The 
sulphur did not even leave a mark. I took a piece of this 
cast iron and fashioned it inte a crucible, and put into it 
some sulphur and iron. On heating the crucible the 
iron and sulphur were quickly melted, but the crucible 
underwent no change.—An. de Chaimic, Jan. 1824. 
4. “ The naturalist’s ¢uide, in collecting and preserving 
the various objects of natural history.”—A Duodecimo vol- 
ume under this title, price 5s. Gd. sterling, has been pub- 
lished by Wm. Swaimon of Liverpool. A work of this 
nature by.a person so well quali ed to give the needful in- 
struction must be valuable toamateu's. An edition of it, 
we should imagine, would be saleable in this country. 
5. Public Utiity.—By an edict of the king of Bavaria, 
a school of Rural Economy has just been established at 
Scuuetspemm, analogous to the agricultural Institute of 
M. de Fellenberg. The pupils are divided into three class- 
es. The first comprehends those who are destined simply 
to subaltern occupations ;—the second those who are par- 
ticularly devoted to practice ; and the third attends to the 
most scieutific concerns of rural economy. Observation 
and experience form the basis of all the instruction here 
given. This establishment, together with the polytechnic 
museum, opened to the public in May last, must be reck- 
oned among the most useful of those which contribute to 
the progress of national Industry. 
6. WurTEMBERG. Organization of the University.—For a 
long time past, in Germany, the students have formed as- 
sociations, either public or private, against which the gov- 
ernment has found it necessary to take precautionary 
measures. In vain has it forbidden those which are known 
under the names of Landmanschafften, Burschenschaffien, 
&c. ; they have been ostensibly dissolved, but only to re- 
vive under other denominations unknown to the authority.
