just the same way in traversing for the first time a locality through which they will have to return. And yet, as has already been stated, these insects have no true brains. Considerably removed from insects are the vermes, or worms. Man, in his overweening opinion of self, would hardly credit the earth-worm with the possession of any mental qualities; yet it has been shown that it can reason, and can communicate after its fashion with its fellows. It is now my intention to prove that it has the power of memory. Has the reader ever seen an earth-worm trying to carry into its burrow a pair of pine-needles joined at their bases? It knows just where to seize the pair. This it determines by feeling, or moving its head along the needles, the sense of touch being very acute in this portion of its body. Hardly ever is a mistake made by seizing the free or apical extremities. Once it has discovered where to act, this position is fixed in memory, and the animal exercises the latter power in dealing with objects of the kind in all subsequent operations. Almost any living being can by means of the faculty of memory be taught by man. But were it absent, no teaching would be of the slightest avail. In most cases where an animal is ferocious, I firmly believe that fear, and not ill-temper, is the real cause of its conduct. Let a little kindness be shown, and the animal will never forget it. Such acts, repeatedly performed, assure it that your intentions are well-meant, and it soon learns to recognize in you a friend. The memory of your goodness will often be recollected after long years of separation, and the most joyous feelings be manifested at the sight of your presence upon returning home. Everyone who has had personal experience of domesticated animals must have remarked the great strength and endurance of their powers of memory. The dog, the cat, the horse and the ass afford so many familiar anecdotes in point, that I shall be obliged to pass them over and restrict my illustrations to a few animals about which little has been said.
