But lying in the central axis of the body it furnishes the very best possible attachment for muscles. Around this primitive notochord was a layer of connectile tissue which later gave rise to the vertebræ forming our backbone. The nervous system on the dorsal surface of the notochord consists of the brain in the head and the spinal marrow running down the back.
This may also be as simple as the dorsal breathing-holes of a tobacco barn, gorgeously imposing as an Oriental pinnacle, or it may be a part of the chimney; only let it be at the very summit, ample, and so arranged that an adverse wind shall not prevent the egress of the rising currents of air.
The male is recognisable by his slightly smaller size. The operation commences. Raising the ends of the wing-covers, the assailant seizes her victim by the extremity of the abdomen, from the dorsal side. She pulls at him furiously, eagerly munching with her mandibles. The victim, who is in the prime of life, does not defend himself, nor turn upon his assailant.
Therefore, in this case, if it be an old one, taking the A D current, very mild force, apply the uterine electrode, N. P., to the os uteri, and treat over the lower dorsal and upper lumbar vertebræ with P. P., long cord. Treat five to eight minutes, three times a week.
Mademoiselle Nioche, apparently, had come to seek a more rapid advancement in London, and another glance led Newman to suppose that she had found it. A gentleman was strolling beside her, lending a most attentive ear to her conversation and too entranced to open his lips. Newman did not hear his voice, but perceived that he presented the dorsal expression of a well-dressed Englishman.
Inside we find the first blood-vessels, an upper or dorsal vessel, corresponding to the aorta, between the gut and the dorsal cord, and a lower or ventral vessel, corresponding to the subintestinal vein, at the lower border of the gut. Now, the gills or respiratory organs also are formed at the fore-end of the alimentary canal.
When fresh caught from the sea the body is yellow of various shades, striped and spotted with vivid blue on the head; the dorsal fins are pale brown with dark longitudinal bands; the ventral, caudal, and anal fins being bluish-black.
They rattle us along over unevenly paved streets, and whiz us around corners with the rapidity of thought; an uncomfortable sensation in the region of the dorsal vertebræ, resulting from the unusual bumping process, and a fear lest, haply, we may be flying out of our carriage at a tangent into somebody's shop front, a pleasing reflection should we take a header amongst china.
At first the chorda only consists of a single row of large entodermic cells. It is afterwards composed of several rows of cells. In the Ascidia-larva, also, the chorda develops from the dorsal middle part of the primitive gut, while the two coelom-pouches detach themselves from it on both sides. The simple body-cavity is formed by the coalescence of the two.
Clare, too, after bidding the girl farewell, was wrought to aching thoughts and quivering lips. But his sorrow was not for Izz. That evening he was within a feather-weight's turn of abandoning his road to the nearest station, and driving across that elevated dorsal line of South Wessex which divided him from his Tess's home.
