To see this picture, taken from a height of only 5 Millimeters, we should need a
microscope. Again there is a member of the animal kingdom visible: one of the
water mites we saw on the previous drawing, a cyclops (1). This is again not
the most likely thing to happen, that it would lie thus comfortably with its
feelers over the edge of the cut in the girl's finger, but it could happen! In the
section of the skin we notice the horny keratin layer (2) on top. Under it is the
Malpighian layer (3) with its numerous cells and the orifice of a sweat duct (4).
Under that lies the Corium (5) with its nerve papillae (6), small blood vessels (7),
and fat cells (8). We see how the mosquito's proboscis (9) sticks into the skin.
In the smaller of the two quarter circles in the right hand bottom corner we
can now just see the bacterium (10).
