^{page 550 note 2} A horizontal section of a corallite, if only a little way below the calice, should correspond as nearly as is practicable with the surface of the calice, for otherwise some of the septa would be cut through much lower down than other. Indeed, the same septum would be reduced very unequally and the endotheca more exposed in one place than other. As, however, there is no reason to suppose, primâ facie, that any important difference exists between the two sides of a tall corallum, a horizontal section section taken low down seems unobiectionable.
