In spite o?' thr~.t, it must be aorriitted that this concept is not
very cle~ariy dci.ned. ` The concept has no doubt` been derived from
the observation that various kinds of mined coal cont~iri va~ryiin
armounts of carbon, ii 4 e f, the chemical element C, and thus are to
a greater or ].user degree coalf'ied (in polish, the terms ' owegw
lone' or ' zwegonet [ instcr,.d of '+uweglone'I] had previously boon
used) o It has been round that the properties of coal vary in re
la;tion to its crxbori contente The carbon content icy i.nver ,e]y re-

of a. given coal-samples
The problem o1: determ.Lning the degree of coa,iificati on
would thus be solved, i?' it were not for the ?`act that different
petrographic coanponents of the s~ rte piece of coal contain many
different proportions of carbon a d of volatile matter This is
clearly apparent when the litrain and fusain of to seine coal sample
