Others weather into large cuboidal blocks which may produce structures resembling cyclopean masonry.

It is lined by an epithelium which here consists of a single layer of columnar 17 or cuboidal cells with large nuclei.

In their place has come a cuboidal mass, twice as long as it is broad or high, with a place in front for mouth and eyes, and a foolish-looking leg under each corner.

These ragged, angular, and mostly cuboidal blocks, resembling the ice-pack of St. Lawrence River, have apparently been borne down by subsequent lava-currents, which, however, lacked impetus to reach the lower levels of Las Cañádas.

Now such joints are supposed to be analogous to the partings which separate volcanic and Plutonic rocks into cuboidal and prismatic masses.
