These cases are naturally much less numerous, for the simple reason that the senses of smell and taste are not the ordinary agencies of our relations.

However, we are certain that telepathy is a universal phenomenon and that none of our senses are refractory to this means of communication. In the first place several experiments have yielded convincing evidence and in the second, we have examples spontaneously observed. We cite only the following:

Telepathic Hallucinations, p. 327.

January 26, 1885.

In March, 1861, I was living at Houghton Hants. My wife who had delicate bronchial tubes was kept in the house at this season. One day, as I was rambling along a path bordered by hedges, I found the first wild violets of the spring and gathered the flowers to carry them to my wife.

At the beginning of April I felt seriously ill and in June left the country. I had never told my wife exactly where I found the violets and, for the reason mentioned, I had not for many years walked with her in the place where I gathered the flowers.

In November, 1873, we were at Houghton with some friends: my wife and I took a little stroll in this path. On crossing the place a memory of the spring violets I had plucked over twelve years before suddenly came into my mind. After the usual interval of about twenty or thirty seconds my wife remarked. "It is strange, but if it were not impossible, I would declare that I smell violets in the hedge."

I had not spoken, nor made the least gesture or movement to indicate the subject of my thoughts, and the perfume of the violets had not come into my memory. The only thing of which I had thought was the place where the violets grew upon the bank. I have an extremely exact memory of places.

Such are the facts: we might multiply examples for each of these series, for the documentation has become extremely rich since the Society for Psychical Research has gathered together the material, and similar investigations have been undertaken by those scholars who were willing to interest themselves in these phenomena.

It follows that among all human beings there is a possibility of transference of all sensations in general, and particularly of thought, at a great distance and that images thus transmitted are not illusory. In other words, telepathy can no longer be denied. Aside from this, there exist certain phenomena which seem also to produce objective images, where there is an absence of all objectivity. We shall see that there is no way of confusing these with the preceding telepathic cases.
