A LEAF OB TWO OUT OF H. A new and very interesting flower has been found on the'lstnmus of Tehuantepeo. It is a red, white, and blue flower, which grows on a tree about Che size of a guava. In the morn ing the flower is white, at noon red, and at night it is blue, but it is only at noon that it gives forth any perfume. A BLIND SALAMANDER. Mr. 0. M. Blackford, of Washington, 8.C., in a letter to "Nature," describes a blind salamander found in an artesian well in limestone rock at San Marcos, Texas. It is three to four and a half inches long, has a large head, eyes covered by skin, scarlet gills like those of a fish, and its body iB of a dirty white colour. The legs and feet are and the tail has a fin like that of an eel. Two living specimens are now in the Aquarium of tho Fish Commissioners at Washington. They are supposed to come f rem a subter ranean lake in communication with the well. A BIRD'S APPETITE. The late Rev. J. G.Wood used to say that if a man could eat bb much in propor tion to size as an insectivorous bird he would consume a whole baron of beef for his dinner. The robin; for instance, is a moßt voracious insect eater. It has been calcu lated that, to keep a robin up to its normal weight, an amount of insect food is required daily equal to an earthworm H feet in length Taking a man of average weight, and measnr-, ing bulk for bulk with the robin, he tried to calculate how much food he would con sume in 24 hours if he ate aB much in propor tion as the bird. Assuming a Bologna sausage to be nine inches in circumference, which would be in proportion to the man about what the earthworm is to the robin, he found that the man would have to eat 67 feet of such Bausages in every 24 hours.
