And further still, the boots I have worn are so saturated with my own magnetism, my own vital activity, that if anyone else wear them I feel it is a trespass, almost as if another man used my hand to knock away a fly.

I doubt very much if a blood-hound, when it takes a scent, _smells_, in our sense of the word.

It receives at the infinitely sensitive telegraphic center of the dog's nostrils the vital vibration which remains in the inanimate object from the individual with whom the object was associated.

I should like to know if a dog would trace a pair of quite new shoes which had merely been dragged at the end of a string.

That is, does he follow the smell of the leather itself, or the vibration track of the individual whose vitality is communicated to the leather?
So, there is a definite vibratory rapport between a man and his surroundings, once he definitely gets into contact with these surroundings.
