In quality of a doubter, I have a long time filled my vocation. I have doubted when they would persuade me, that the glossopetres which I have seen formed in my fields, were originally the tongues of sea-dogs, that the lime used in my barn was composed of shells only, that corals were the production of the excrement of certain little fishes, that the sea by its currents has formed Mount Cenis and Mount Taurus, and that Niobe was formerly changed into marble.

It is not that I love not the extraordinary, the marvellous, as well as any traveller or man of system; but to believe firmly, I would see with my own eyes, touch with my own hands, and that several times. Even that is not enough; I would still be aided by the eyes and hands of others.

Two of my companions, who, like myself, form questions on the “Encyclop?dia,” have for some time amused themselves with me in studying the nature of several of the little films which grow in ditches by the side of water lentils. These light herbs, which we call polypi of soft water, have several roots, from which circumstance we have given them the name of polypi. These little parasite plants were merely plants, until the commencement of the age in which we live. Leuenhoeck raises them to the rank of animals. We know not if they have gained much by it.

We think that, to be considered as an animal, it is necessary to be endowed with sensation. They therefore commence by showing us, that these soft water polypi have feeling, in order that we should present them with our right of citizenship.

We have not dared to grant it the dignity of sensation, though it appeared to have the greatest pretensions to it. Why should we give it to a species of small rush? Is it because it appears to bud? This property is common to all trees growing by the water-side; to willows, poplars, aspens, etc. It is so light, that it changes place at the least motion of the drop of water which bears it; thence it has been concluded that it walked. In like manner, we may suppose that the little, floating, marshy islands of St. Omer are animals, for they often change their place.
