nomena of sound may be traced, by experiment and mathematics, from 
agitations of the air to the action of the generated vibrations on the auditory 
nerves ; and the sound as to quality , intensity , and pitch, results from the ' 
character of the initial disturbance. But these are non-material , or spiritual 
sensations , in exact co-ordination and correspondence with their immediate 
material antecedents, but in essence they are in quite a different category. 
The same kind of argument applies to light as produced by vibrations of the 
sethereal medium. Hence it follows that physical science, as understood 
by indications of the senses, is concerned with non-material as well as 
material entity. Just so, after we have derived the material conditions of 
the action of physical force from the qualities of the atoms and the aether 
as above defined, we have not reached the essential quality of force. To 
do this we must take account, as has just been illustrated, of non-material as 
well as material essence. We must admit that the production and mainten- 
ance of those primary conditions from which it is the province of mathematical 
reasoning to show that the action of physical force flows, are due to the 
operation of Mind ; the conditions, namely, of the permanence of the qualities 
of atoms, of the constitution of the aether and its intrinsic elasticity, and as 
depending thereon, its pressure, and law of pressure. Intelligence was em- 
ployed in designing the qualities appropriate to the intended purposes ; Will 
and Power were required for giving them existence, and are also constantly 
exercised in maintaining their effects. Our own consciousness tells that 
will and power are concerned when we move our limbs, which we are 
enabled to do by means of the control, limited by the conditions of 
organization, which our Creator has given us over the physical action of 
the sethereal medium. iC In Him, we live, and move, and have our being.” 
These views exclude action at a distance, and at the same time assign its 
truest meaning to the law of the Conservation of the Energy of the Universe, 
the word energy in this acceptation not having the mechanical meaning 
assigned to it by modern physicists, but being a definite expression of the 
exercise of spiritual power. 
REMAKES BY THE KEY. PREBENDARY IRONS, D.D. 
If there be any truth in the rumour referred to by the noble Lord who 
has favoured us with this paper, viz., “ that the scientific and even the 
clerical world is fast drifting into unbelief,” the fact cannot be attri- 
buted to any scientific or critical successes thus far achieved against the 
Christian position, but to other and distinct causes. After the experience 
of the last few years, we are justified in saying that the confident anti- 
Christian assertions of literati and experimentalists have been met and 
examined, and that the ingenuous fearlessness of educated Christians 
(specially shown in this Institute) has really silenced the offensive preten- 
sions to “ enlightenment to which the quasi- scientific had accustomed the 
last generation. Bishop Cotterill’s papers, by their careful and analytical
