The shells accumulate at the bottom of moderately deep seas to form “Globigerina ooze” and are preserved thus in the chalk.

Chalk is well known to consist largely of foraminiferal shells, mostly vitreous, like the north Atlantic globigerina ooze.

He wants to see, touch, examine the Globigerina ooze of the ocean bottom, the volcanic debris of the ridge top.

Our continents are shown to be built up mainly of "shore-deposits"; and even the chalk, which is so often said to be the exact equivalent of the "globigerina ooze" now forming in mid-Atlantic, is shown to be a comparatively shallow-water deposit formed in inland seas, or in the immediate vicinity of land.

Dr. Wallich ascertained that the sea-bottom at this point consisted of the ordinary Globigerina ooze, and that the stomachs of the star-fishes were full of Globigerinæ.
