LIII. — Remarks on the Distribution of Animal Life in the Depths of the Sea. By M. Sars* Upon the question, so interesting and important in many respects, how far animal life extends downwards in the sea, and of what kind are the animals which occur in the great depths, the observations of the last few years have, as is well known, furnished us with some valuable information. This, however, is still extremely scanty, and embraces only a very small number of animal forms accidentally brought to light ; they are, it would appear, little more than iso-lated glimpses of the life that stirs in the abysses of the ocean. In order, if possible, to obtain a more comprehensive know-ledge of this subject, investigations have been made near our * Translated from the ' Videnskabs-Selskabs Forbandliuger ' for 18G8, pp. 246-275, by the Rev.
