Der Originaltext lautet: "The fourth tribe which M. Dujardin has included
among the rotifers consists of the Tardigrada, or slowsteppers,
popularly called 'water-bears'. They are very fully described in 'Marvels of
Pond-life;' but a sight of the original is required to give a full idea of
the creature's comical aspect. I first observed it when examining a quantity
of weed in a live-box. The head and a pair of feet were suddenly poked into
view, and I thought, 'here is a small larva,' and expected a long body
in several joints to follow, when all at once the creature showed in its
completeness, walking along a stalk, and more like a young puppy with eight legs
than can be easily believed! Mr. Slack says his specimens had no visible eyes,
and that these organs are, according to Pritchard's book,¤ 'variable and
fugacious.' My water-bears had eyes, and of very respectable size and
blackness. The first specimen which I met, being given sufficient room to
climb by slightly raising the life-box's cover, seemed for some minutes
as if staring at me, and in that position not a little resembling the white
polar bear, its colour being somewhat pale. I felt inclined, when looking
at this animal, to side strongly with those naturalists who (as Dr. Carpenter
mentioned) regard the Tardigrada as altogether distinct from the true
rotifers. Mr. Slack's account of them is, that they are, physiologically
speaking, poor relations of the great family of spiders."
