on the elastic form at a very low temperatare, at 
(een than 60>. Hence glass may be very . 
ly corroded by being inmensed in this vapour, As. it. 
combines with the silex of the glass, it becomes a more 
elastic fluid, called the superfiuat of silex, In etching 
round vessels of glass, it is not so convenient to use 
the wall of wax to contain the liquid; and hence it will 
be better to etch bodies of such form with. vapour, ob- 
serving uot to apply it so hot-as to melt the wax. 
When the plate has been exposed. to the action of 
pulp com of pounded fluor spar and sulphuric 
ed, till finest hoes are correded sufficiently, which 
can only be ascertained by trial and observation, the 
acid mass is to,-be removed, and the plate washed. with 
clean water, and dried so a cannes _ parts cor- 
roded sufficiently are to be stopped out with turpentine 
varnish used in etching copper, The rest of the pro- 
i isely the same as that of the copper- 
plates, lying every time the same quantity of pound- 
ed at ak. The pulp which has been used.once, 
may sometimes be used again, since it will be capable 
ing so long as any effervescence appears. 
of etching upon steel, has been practised at 
Birmingham for ornamenting polishedsteel. 
The corroded part becomes a dead white, while the part 
unafiected remains polished. Those parts intended to be 
from the acid, are drawn with turpentine 
varnish, while that which is to form the white ground 
is left bare. The where the acid is to be exposed, 
is first surrounded by a wall, of a mixture of bees wax 
and pitch, with the eddition of a little tallow: The 
acid employed is the nitric, diluted with 3 or 4 parts 
of water, more or less according to the strength of the 
acid, The proportions will be those which produce 
the whitest ground, This will be easily formed, by. 
trying different strengths of acid, with a pair of polish- 
ed steels kept forthe purpose, This beautiful art:is; 
much assisted by bluing and gilding. - (c: s:):

Eton College was founded in 1440, by Henry VI. for a 
“ provost, ten priests, six clerks, six choristers, 25 poor 
grammar scholars, witha master to teach them, and 
25 poor old men.” It now supports a provost, seven 
fellows, two schoolmasters, two cadets, seven clerks, 
70 scholars, and 10. choristers, with various other: offi« 
cers and assistants. T'welve of these scholars are annu« 
ally elected to. King’s College, Cambridge, to which 
they are removed; according to their seniority, as soon 
as any Vacancy occurs, the av “number of vacan- 
cies being’about nine. in two years. ‘They: are entitled 
to a fellowship, after having: continued there three 
years. ‘Two scholars arealso sent annually. to. Merton 
College, Oxford, where they are named ‘ostmasters,

Besides the king’s scholars, there are generally fron 
300 to 350 independent scholars, or. oppidans, as.they 
are called, educated here. ‘They are the sons.of noble-

Eton College consists,of two courts or, quadrang! 
divided, by a tower or gateway. In, one of 
these is the school, the chapel, and. ings. for,

lower and upper, each, of which are subdivided into 
three classes, The other ynarnale is, occupied: by, 
the library, the. provost’s lodgings, which are in. the 
front, and the fellows’ apartments., The library, which 
is-on the. south,side,. is one of the best: and most ele+
