Dexter paid attention to the process, and felt that there was not much to learn: only to find out a hole the burrow of the cray-fish, and then thrust in his hand, and, if the little crustacean were at home, pull it out. The process was soon learned, but the temptation to begin was not great.
Agassiz, having previously referred some of these fragments to the class of fishes, was the first to recognise their crustacean character, and, although at the time unable correctly to determine the true relation of the several parts, he figured the portions on which he founded his opinion, in the first plate of his "Poissons Fossiles du Vieux Gres Rouge." Parka decipiens, Fleming.
If we go still further back in time, we discover, in the oldest rocks of all, the remains of animals, constructed on the same general plan as the lobster, and belonging to the same great group of 'Crustacea'; but for the most part totally different from the lobster, and indeed from any other living form of crustacean; and thus we gain a notion of that successive change of the animal population of the globe, in past ages, which is the most striking fact revealed by geology.
"Ah, I knew you would see that. As though human life and character were what would say?" "I'd say crustacean; their anatomy all on the surface. Such stories are not life, life in the round; they're only paper silhouettes of the real life's poorest facts and moments. I state the thought poorly but you get it, don't you?" The girl sparkled, not so much for the thought as for their fellowship in it.
This extraordinary crustacean is one of the oldest of living animals in its history, as it is closely related to the Xiphosura and even the Trilobites of the Primary Epoch, which existed millions of years ago. These Massachusetts "Indians" described to Champlain a wonderful bird which at some seasons of the year they caught in snares and ate.
The leading crustacean type is the TRILOBITE, which takes its name from the three lobes into which its shell is divided longitudinally. There are also three cross divisions, the head shield, the tail shield, and between the two the thorax, consisting of a number of distinct and unconsolidated segments. The head shield carries a pair of large, crescentic, compound eyes, like those of the insect.
His "Hear All!" still deafens memory's ear. I remember that he had a queer way of sidling up to one, as if nature in shaping him had originally intended a crab, but thought better of it, and made a town-crier. Of the crustacean intention only a moist thumb remained, which served Mr. Newman in good stead in the delivery of the Boston evening papers, for he was incidentally newsdealer.
Fowk 'll hear ye. Haud yer tongue, I beg. She may dee i' the strae for me. I s' never put han' to the savin' o' her, or her bairn aither," said the midwife, thinking thus to pacify her. Then, like the eruption following mere volcanic unrest, out brake the sore hearted woman's wrath. And now at length the crustacean was too much for the mollusk.
He always kindled as he spoke, and with a marvellous magnetism communicated his glow to those who listened. I have seen him stand before his class holding in his hand the claw of a crustacean. In his earnestness it seemed to be for him the centre of the creation, and he made us all share his belief. Indeed, he convinced us.
It is comparatively huge in its proportions, its average extreme length being the 1/1000 of an inch. Its normal form is rigidly adhered to as that of a rotifer or a crustacean. Its body-substance is a structureless sarcode.
