Otters in the Lea at Hoddesdon.—The Fishing Gazette of May 7th records the capture of two otters (male and female), which were shot near the stone railway bridge, Rye House, Hoddesdon, on Saturday, April 30th, by- Mr. Walter Huddlestone, the two weighing over 27lb.—viz., 151b. and 121/2lb. respectively. Both of them were killed with one discharge from the gun. They were shown and weighed at the "Rye House" Hotel in the presence of the proprietor and several visitors. The New "Whale Gallery" at the British Museum of Natural History.—One of the latest and certainly not the least valuable and interest- ing of the innovations at Cromwell Road which we owe to the museum-genius of Sir William Flower is the new Cetacean Gallery—an exhibition of these gigantic mammalia which we suppose is unparalleled in the museums of Europe. Some of the species are demonstrated as "skeleton-models," the external contour of the body being shown by a casting over the actual skeleton on one side, the bones being readily seen in proper anatomical position on the other side. By this ingenious device, not only can a realistic idea be obtained of the actual appearance and extreme specialization of external form of the living animal, but at the same time correct notions may be gained of the extraordinary modification of the mammalian skeleton exhibited in the whales, particularly of the skull, the fore limbs and the position of the small bones representing the aborted hind limbs. For the first time in the development of
