Dr. John Ryan, the chemical lecturer to this institu-
tion, is at present delivering a course 01 lectures t.n, the
Philosophy of heat and cold. These lectures are t-uni-
rably adapted for this season of the year,

octor, insteai usual of merely confining himself to the
routine of Writers and lecturers on this imprtent sub-
Pet, treated principally of the matt-T in connexion with
tMeteorology and the economy of clothing. After in-
doting the subject by treating of the various sources
of heat, Dr. Ri-an proceeded to consider the charge of
condition produced by this imponderable in every de-
oscription of matter. Ilis illustrations in this department
f.his lectures were most happy and numerous, com-
prtsing a condensed description of thermometers and
PYrometers ; under this had, also, he explained very
simply and beautifully the theory of ventilaton, the
cause of the trade-winds, land. and sea breezes. The
lecturer then proceedei to consider the communication

Ryan explained most concisely- and satisfactorily the
theory of dew, and the cause of its deposition on some
sturfaces and not upon others. The Doctor showed by

as so much enhanced in the world's esteem, has signi-

countries by this spectacle of a great statesman, whose

selecting the period when his every movement is of uni-

INIPUDENT PLAGIARISM.
teiOn 'Wednesday evening a scene of a most unusual and
g character occurred in the Lecture Theatre of
the City Literary Institution, in Aldersgate-street. An
Irish gentleman, described in the prospectus as " J, J. a

two lectures on the study of history, having recommended to the comm. tt
