 PROF cRosHYs WESTERLY ADDRESS. s'Conscrvation of Energy and the Theory
 of Gratitation" His Theme.
 One of the most interesting and in- structiye of the series of lectures given | in the rooms of the Young Mems Catho- | lie Literary association, was that de- | Crosby of the public school, his subject 1 being Conservation of Energy and the | Theory of Gravitation."
 The speaker began by explaining the law of gravitation as generally stated and accepted for the last two hundred years, in brief that gravitation is force which draws, attracts, pulls bodies together.
 In order to comprehend another the ory of gravitation, we must consider i briefly two great fundamental laws of | modern science, viz: 1.-The conservation | of force or energy" and "the correlation of force or energy. By the first is meant that every force or energy is conserved or preserved. so that no portion of the force or energy is lost. The sum total of all tine forces or energies of the uni verse remains the same no matter how much any force may change its mode of action. This can be illustrated by d law of matter. No particle of matter is ever destroyed or annihilated. To prove this a number of simple experiments were given. In the case of matter we can easily trace the changes; in the case of force we cannot often so readily trace the changes.
 By correlation of force or energy Is meant that every force or energy is di- rectly related to a force or energy from ) which it comes, and to a force or energy into which it passes. There is no such
 thing as force independent, unrelated. Several simple experiments were given to prove thls law, among them the pro- duction of the arc light and the incan- descent light by means of hand dyna- mo which was placed on table before
 the audience. The muscular energy of the hand and arm, and the mechanical energy of the machine were changed into the molecular energy of electricity and of heat, thus producing the different lights.
 There is form of matter which does not directly make itself apparent to any , of our senses. This kind of matter is l called ether, an exceedingly elastic, tenE- ous fluid which pervades the whole uni verse. It exists in the pores of all solids
 and extends out and beyond the sun
 ready to take up and transmit any mo-
 tion, any force. All motions and forces
 which are utterly lost to the apprecia- |
 work i'll this ether. The new theory of gravitation states that every heavenly
 body is floating in the depths of this vast sea of ether. The intense heat of these bodies sets the ether in motion D causing in it waves of infinite number
 and rapidity, which continue their mo- tion to the most distant DOT
 these waves strike upon other
 starry suns the ether waves are
 stopped and as they strike a vast body, n especially when intensely heated, the
 waves arc converted into heat again F and started back to strike upon, and be :. stopped by, other starry suns. Thus the e theory accounts for keeping up the heat I of the suns. n Now these ether waves are not all de a voted to producing and reproducing l. heat. They pelt upon what they strike and thus produce a vast number oi a pushes, which result in giving motion tc $ the heavenly body, thus producing n gravitation. The motion of the earth il Q its orbit and the falling of bodies on the i earth were explained and illustrated s by this theory. It is asserted tha r. this new theory puts gravitation under a the law of correlation of forces, wherea! IF there is no place for this law in the olC , theory. Under the old theory gravita q tion comes from no other force anC Q passes into no other force, but stands il alone as the only solitary and independ s ent force in the universe.
 In conclusion the lecturer said: 1T, I, assail the old theory is like attempting .;i to undermine the foundation of al o science. How many things are assaileI $ at the present day. The generally re v v ceived theory of the formation of co,, n n is attacked, and it may bn necessary t' e modify it, if not to set it aside entirely ' IrreligiOus scientific men claim to b J agnostics ill spiritual things, bu gnostics in their own realm of science '. They say I know in science, but I d, ;;s not know in religion. Never were true 10 II. words spoken than by St Paul when h. y said: The things which are seen ar 'f temporal, Lut the things which are no " seen are eternal Some day, we shal y know.
 The lecturer explained in detail eacl
 of the points presented and performed -s number of chemical and electrical eX ,o periments. He did not advocate tn ~ new theory, but rather presented it, for l. as he said, whether we hold to the ol' l. theory or accept the new one, ston ,o will fall to the ground. water will rul ,I down hill, we shall tread upon solit n earth and the planets will move in thei
 orbits just the same.
