We may regard from the same point of view the sense of taste, the nerves of which have a still narrower range, and are apparently differently affected in animals than they are in man--substances disagreeable to him being relished by them, and of course affecting the taste differently. We are not sure that there are not senses which appreciate conditions of matter, of which we have no conception. There are insects which apparently have organs bestowing senses unlike our own. Their antennæ have no corresponding organs in the higher animals, and the conception of the world which these give has no analogy in our minds. As the senses are thus cognizant of narrow belts of sound and light, leaving unknown stretches on either side, so what is called matter may be the narrow range recognized by our finite powers as a whole, on either side of which may lie stuffs of widely different qualities and possibilities. A DEAD VIEW OF DEAD WORLDS.--Pausing to consider the received theory of force, as an explanation of the causes of the world--creation, we shall find that it fails to meet the high promises it vauntingly makes. According to the received theory of force, every manifestation of power and energy on the earth is originally derived from the sun. The growth of plants and animals, and all the activities displayed by the latter, are derived from their food, which was produced by the light and heat of the sun. In illustration of the sun’s incalculable power, take, for instance, the rain fall of one-tenth of an inch extending over the United States. Such a rain-fall has been estimated at ten thousand millions of tons, which the heat of the sun had raised at least to the height of one mile. It would take all the pumping engines in the United States a century to lift this amount of water back again to the clouds. If the force is so great as displayed in the rain-fall of one-tenth of an inch, how incomprehensible the power which lifts the entire amount of water evaporated, amounting to, at least, forty inches! Yet the force of the sun, manifested on the earth, is an inconceivably small part of that radiated, for the earth only receives in the proportion that its surface bears to the sphere of its orbit, and how incomparable is its diameter of 8,000 miles to that of a sphere 184,000,000 across. The combined surface of all the planets would receive a scarcely appreciable ratio of the entire amount which, unimpeded, flies away into the abyss of space. The energy radiated at the surface of the sun is estimated at 7,000 horse power to the square foot, and if the sun was a mass of coal, it would have to be consumed in 5,000 years in order to supply it, and in 5,000 years would have to cool down to 9,000 degrees, C. If the nebular hypothesis be received, the contraction would supply the loss for 7,000 years before the temperature would fall 1 degree, C.
