ROYAL POLYTECHNIC INSTITU
TION.

We are exceedingly sorry io inform our readers and
the public, that Dr. Ryan has been prevented from
lecturing at the above establishment, in consequence of
severe indisposition, but has found a most able substitute
in Dr. Bachhoffner, who has been giving a series of
lectures on chemistry in the theatre of this institution.
fie has chosen for his subject that portion of the science
which relates to combustion. Light, says the Learned
Doctor, is produced without combustion, a fact unknown
among the ancient chemists, who asserted the exist•
ence of an ingredient termed phlogiston. This, in latter
years was objected to, and Dr. Priestly entirely over-
threw the theory when he made the important discovery
of oxygen gas ; nevertheless, this Professor remained to the old principle f phlogiston, and, although
he had satisfactorily proved its falsity, still advocated it.
These remarks were illustrated with several interesting
experiments. The Doctor next alluded to the imperfect
ventilation of dwelling houses in the metropolis, in which,
he said, if you only sat by the fire-side, that fire-side so
famed is poetry as the Englishman's, you were nearly
" roasted on one side, while you were almost frozen on
the other," and when entering a friend's house, you were
invariably asked to sit on a particular side, as the other
was subjected to draughts. This, he said, arose from
imperfect ventilation, greatly prejudicial to health, pro-
ducing in many cases colds and rheumatism, and in the
young and delicate, consumption. The Doctor con-
cluded by experinientally showing that combustion was
alone caused by intense chemical action.
