Its early characteristic was the acquisition of a chitinous coat over the body. Embryonic indications show that this was at first a continuous shield, but a type arose in which the coat broke into sections covering each segment of the body, giving greater freedom of movement. The shield, in fact, became a fine coat of mail.
All this time the effect of the poison has not spread beyond the inoculated segment. At any point where the sting enters, anatomy informs us of the presence of a nervous nucleus. Is this centre directly smitten by the weapon? Or is it poisoned with virus, from a very small distance, by the progressive impregnation of the neighbouring tissues?
Do not Nauplius-like states in this case also precede the Zoea? The last segment and the last two pairs of feet of the middle-body are wanting. The developmental history of Mysis, the near relationship of which with the Shrimps and Prawns has recently again been generally recognised, has been described in detail by Van Beneden. So far as I have tested them I can only confirm his statements.
In many cases his procedure is, when the analytical equivalents are set down, seen to amount to real integration; this is so with his investigation of the areas of a parabolic segment and a spiral, the surface and volume of a sphere, and the volume of any segments of the conoids and spheroids.
I therefore sent to the Congress proposed legislation to strengthen this woefully weak segment of the U.S.-flag fleet by removing certain disincentives to U.S. construction of dry bulkers and their operation under U.S. registry.
Thus, for instance, Ammophila hirsuta fixes hers, by one end, cross-wise, on the Grey Worm, on the side of the first prolegged segment. The eggs hang over the caterpillar's back, away from the legs, whose proximity might be dangerous.
But this morning he lingered, contemplating with an unobtrusive scrutiny the occupant of the adjoining chair, a small, angular, hard man, whose brick-red face was cut off in the segment of an abrupt circle, formed by a low-jammed green hat. This individual had just briskly bidden his bootblack "hurry it up" in a tone which meant precisely what it said. The youth was doing so. "George," said Dr.
Or that it is impossible to draw more than one right line betwixt any two points? should he tell me, that these opinions are obviously absurd, and repugnant to our clear ideas; I would answer, that I do not deny, where two right lines incline upon each other with a sensible angle, but it is absurd to imagine them to have a common segment.
These latter have been grouped in the four quadrants, a much more effective arrangement than the cylindrical layer of the schematic worm. Furthermore, the animal has on each segment a pair of fin-like projections, stiffened with bristles, the parapodia. These are moved by special muscles and form effective organs of creeping.
On the first segment of the thorax is a brown sash, interrupted in the middle; lastly, there is a small black speck on each side, behind the third segment. This is the initial costume. Presently orange-red will take the place of the pale amber.
