      "Related claim <https://w3id.org/delphi/resource/claim/thompson1917-ch09-11> (analogy): Thompson explains the six-rayed hexactinellid spicule by vesicles packed in linear series, so that the spicule follows the edges of a system of cubes rather than of hexagons or dodecahedra: the arrangement he invokes is the cubic P mode of Bravais's fourteen. An analogy of packing between cells and lattice points, not a statement that the sponge is a crystal.";
