SCIENCE GOSSIP.
Professor Agassiz has discovered "a fish which builds a nest." Wonders are only just beginning. Other Professors, envious of Agassiz's good fortune, will be stimulated to renewed study of the Animal Kingdom; and the result will be that at no distant day we shall see the great Zoological collections, here and in America, enriched by the addition of a glowworm which lives in a hive, a tortoise which hops from bough to bough, an oviparous rabbit, and a lobster whose diet consists exclusively of salad. The fable which deluded our childhood may yet be realised, and pigeon's milk take its place amongst the common articles of a free breakfast table.
