Abstract
DR. CARPENTER, in his recent lecture at the Royal Institution on “the Temperature and Animal Life of the Deep Sea,” speaks of the resemblance of the globigerina mud to chalk as being “greatly strengthened by the recognition of several characteristically cretaceous types among the foraminifera scattered through the mass of globigerinæ, of which it is principally composed; as also of the Xanthidia frequently presented in flint. (NATURE, vol. i., p. 564.)
