ctions of the
ligneous fibre (vulgarly denominated a bundle of fire-wood), and
arrange a fractional part of the integral quantity rectilineally along
the interior of the igneous receptacle known as a grate, so as to form
an acute angle (of, say 25 deg.) with its base; and one (of, say 65 deg.) with
the posterior plane that is perpendicular to it; taking care at the
same time to leave between each parallelopedal section an insterstice
isometrical with the smaller sides of any one of their six
quadrilateral superficies, so as to admit of the free circulation of
the atmospheric fluid. Superimposed upon this, arrange several
moderate-sized concretions of the hydro-carburetted substance (_vulgo_
coal), approximating in figure as nearly as possible to the rhombic
dodecahedron, so that the solid angles of each concretion may
constitute the different points of contact with those immediately
adjacent. Insert into the cavity formed by the imposition of the
ligneous fibre upon the inferior transverse ferruginous bar, a sheet of
laminated lignin, or paper, compressed by the action of the digits into
an irregular spheroid.
These preliminary operations having been skilfully performed, the
process of combustion may be commenced. For this purpose, a smaller
woody paralleloped--the extremities of which have been previously
dipped in sulphur in a state of liquefaction--must be ignited and
applied to the laminated lignin, or waste paper, and so elevate its
temperature to a degree required for its combustion, which will be
communicated to the ligneous superstructure; this again raises the
temperature of the hydro-carburet concretion, and liberates its
carburetted hydrogen in the form of gas; which gas, combining with the
oxygen of the atmosphere, enters into combustion, and a general
ignition ensues. This, in point of fact, constitutes what is popularly
termed--"lighting a fire."

AN IMMINENT BREACH.
In an action lately tried at the Cork Assizes, a lady obtained _fifteen
hundred pounds damages_, for a breach of promise of marriage, against a
faithless lover. Lady Morgan sends us the following trifle on the
subject:--
What! _fifteen hundred!_--'tis a sum severe;
The fine by far the injury o'erreaches.
For _one_ poor _breach_ of promise 'tis too dear--
'Twould be sufficient for a _pair of breaches_!
