This poem starts off by telling about a shell, the chambered nautilus.
Although he was not a transcendentalist and even spoke out against its doctrines, Holmes later came to appreciate Emerson's ideas and wrote an influential biography of the philosopher. Year after year beheld the silent toil 15 That spread his lustrous coil; Still, as the spiral grew, He left the past year's dwelling for the new, Stole with soft step its shining archway through, Built up its idle door, 20 Stretched in his last-found home, and knew the old no more. It also mocks the sorts of written work that would appeal to the proletarian commuters who want something soft, easy, and easily digested for their morning ride to work. There is nothing wrong with the shell. Again, the poet opens with sentence fragments, indicating reverie, dependent for their meaning on the lines that follow: Not for these the paper nautilus constructs her thin glass shell. A nautilus does not have suckers on its tentacles like an octopus does.
Like the closely related octopus, the paper nautilus has a rounded body, eight tentacles, and no fins. Similarly, the arms, unidentified yet clearly human, cling even in statuary form to the Parthenon horse's mane for protection. A dwarf population from the is even smaller, with a mean shell diameter of 11. Holmes and other figures lectured and wrote about the possible abolition of slavery in the territories, which Holmes opposed because he feared the consequences of the building conflict between and the North. Let each new temple, nobler than the last, Shut thee from heaven with a dome more vast, Till thou at length art free, Leaving thine outgrown shell by life's un-resting sea! Histology of the long digital tentacles.
The poem, in fact, was written as a gift to Elizabeth Bishop in return for her gift to Moore of an actual nautilus shell. Quarterly Journal of Microscopical Science. Nautilus pompilius fishing and population decline in the Philippines; a comparison with an unexploited Australian Nautilus population.

Most information is based on observations made of animals in protected environments. What gives structural rigidity, is the transverse form continuous spiral of double curvature, it structurally as the abode of a large snail.
The nautilus has the extremely rare ability to withstand being brought to the surface from its deep natural habitat without suffering any apparent damage from the experience. Year after year beheld the silent toil That spread his lustrous coil; Still, as the spiral grew, He left the past year's dwelling for the new, Stole with soft step its shining archway through, Built up its idle door, Stretched in his last-found home, and knew the old no more. The religious idea that the physical, sensuous world blocks us from uniting with a veiled transcendent reality has roots in the Judeo-Christian and Gnostic traditions. Here the magic formula provides the only standard except for those recollections of Blair not inconsistent with it. How does the species survive? Most shells have about five or six whorls rotations and it has been estimated from fossil evidence that each whorl took from between four months to three years to grow. This entrapment contrasts with the freedom of the mother who releases rather than smothers her young.
