"There is no sound this time," I said.
"It is low tide," he replied, "and the sea is calm. You must will to be upon the sand."
I did so, and in a moment the little wavelets seemed tumbling over my feet, splashing and trickling back over the sand. It seemed impossible that I could be thirty miles from the sea, and nearly a hundred from that sandy beach; for the sea on nearly all our southern coasts, breaking as it does on shingle, can give forth no such sweet sounds as these.
CHAPTER V
In this way Alan Sydney gave me an idea of the limitations of our present sense-organs, and how, by superior knowledge, they may be altered and varied. I was able to feel things at a distance that I did not touch, and touch things near me without being able to feel them.
"It is curious," he said to me at last, when he had been showing some rather singular experiments with regard to perfumes, "that the sense of smell has been allowed to die out so much through lack of cultivation. I once taught a person to read quite easily by various scents. I made an alphabet first of all, which he soon learned, and then by arranging the perfumes in order he soon was able to read by this means quite easily. But there is a still more curious fact that, notwithstanding our present scientific knowledge, people talk of having five senses, even as I have done to you for fear of confusing matters, for there is no such thing as the sense of taste."
"What do you mean?" I asked.
"Taste," he replied, "is simply the combined effect of two senses, touch and smell. If a person loses his sense of smelling he can only taste by feeling; he can detect oil from water, or alcohol from vinegar, sugar from lemon, through the effect that any of these substances have on the more delicate nerves of feeling which are connected with the palate. But we will not waste time in discussing the matter. A few experiments will prove it to any one who is doubtful. I only mention it to show why I had not referred to taste as a means of perception."
He then took me to that part of the room fitted up as a chemical laboratory.
"Now," he said, "I am going to show you some experiments that will surprise you far more than anything which you have seen hitherto. But as I do not wish you to look upon them from the marvellous side, it will be well to explain some of the reasons why quite natural causes may lead apparently to miraculous results. For instance, you look upon your body as an inseparable condition of life upon earth. It is even a question whether you do not really regard it as an essential part of yourself instead of seeing it is nothing more important than a suit of clothes well fitting and adapted to the present conditions and circumstances of your spirit. This latter view, though professed by most people, is but seldom really believed in. From the lowest to the highest every body is formed in one way; the life, or spirit, by its force of attraction drawing certain material elements to its aid for the purpose of growth and development. As the spirit thus grows and develops, its needs, and consequently its outward shape, alter. These elements, so gathered, we call our bodies, and it is as easy to cast off these bodies and put them on again as it is to take off or replace our clothes. If, however, the experiment is tried with an imperfect knowledge it is attended with great danger, probably with what we call loss of life. I will, however, show you an experiment on an animal."
