Scientific Lectures.

Irolessor DoTemuS VIII DeSln THIS evening,
December l, at the Hall OF the Young Mems
christian Association, a course of lectures on
1.-THE Triumphs Of Modern Science" The
course is to consist of four lectures, the
pecond of which will be given on Thursday,
The Sth; the third on Thursday, the 18th, and
the fourth on Monday, the 10Th of December.
All will be brilliantly illustrated by chemical
pnd philosophical experiments Of q novel and
Interesting character, explanatory Of the won
aerfl advances recently made in science. ,
Professor Austin Flint, Jr., win also give
pourse of four lectures at the Hall Of the
Young Mems Christian Association on Friday
evenings during the month Of December. The
)ubjects Of the first lecture will be the general
)tructure Of the human body; wear Of,
bhe organism as necessary condi-
h0n of life and Of exercise OF the
functions; relations Of food to repair classid-
eation Of articles Of food, and preparation Of
food for digestion, and by digestion for nutri-
Hon. The second win relate to the properties
Ind uses of the blood, the physiology Of the
heart and circulation and the physiology Of
ths lungs and respiration. The third will
)reat Of nutrition, development Of power and
endurance by exercise and diet (trainlng),
muscular movements, animal heat, secretion
Ind excretion: The fourth lecture will explain
the regulation and coordination Of the func-
lions through the nervous system, the divi-
bions Of the nervous system, and the nerves of
motion, sensation and special sense. The leo
lures win be accompanied by various expert

| It would be superhuous to tell New Yorkers
how competent are both Professor Doremus
md Professor Flint to exemplify admirably in
(hese courses at least two Of the three ele-
nents Of which, according to Professor Hux-
ley, the best method Of teaching science con-
Sists-lectures, demonstrations and examina-
lions. There Is no doubt that the main
object of lectures-which Is to awaken the
attention and excite the enthusiasm of the
ptudent-may be effected to far greater
pxtent by the oral discourse and by the per-
bonal influence of a respected teacher than in
my other way, And there is no more doubt
That appropriate diagrams, experiments aud
Demonstrations are indispensable in order to
enable the scientific teacher to imprint the
fundamental. irrefragable facts of his science,
not only by words on the mind, but by sensi-
BILE impressions upon the eye and ear and
Touch Of the student.
The lectures announced as about to be
given in the hall of the Young Mems Christian
Association will be at once recognition and
- vr;, -
education. Professor Doremus will demon
strate the truth of the late Prince Alberts
assertion, In an address at Birmingham, that
we owe to science, and to science alone, the
transformation which has gone on around MS
since the laws Of gravitation, electricity, mag
netism and the expansive power of heat have
become known to us-a transformation that
has altered our whole state Of existence-one
might say the whole face of the globe Pro-
fessor Flint will help the public to learn that
rs DR.. Youmans has well said, education is an
affair Of the laws.of our being, involving
wide range Of considerations an affair of the
Air respired, Its moisture, temperature, density,
purity and electrical state; an affair Of food,
digestion and nutrition; of the quantity.
quality and speed Of the blood sent to the
brain Of clothing and exercise, fatigue and
repose, health and disease; of variable volition
and automatic nerve action; of fuetuating
feeling, redundancy and exhaustion Of nerve

ment, family history, constitutional predispo-

surroundings and host Of agencies which
stamp themselves upon the plastic organism
md reappear in character; in short, that it
involves that complete acquaintance with cor
poreal conditions which science alone can
give. The Lecture Committee Of the associa-
lion has deserved we'll of the community by
providing for this winter courses Of scientific
lectures which cannot fail to prove equally
useful and popular.
