A fine and similar exampleof this wonderful provision of nature may be observed in the molar teeth ofthe elephant. * Value of two Whales.—Oil, 20 tons, at £50 a ton, £1,000 ; Baleen, 1^ tons, at £700,£1,050.

Rorqualus major, Hump-back. In the autumn of 1831, a whale of unusual dimensions was observedmoving about in the Firth of Forth, and was ultimately stranded near NorthBerwick, within about twenty-five miles of Edinburgh. I was requested bymy brother, Professor Knox, to visit the locality, and endeavour to purchasethe animal. This I accomplished, after much trouble, and no small cost; thecomparative anatomy was ascertained ; the most interesting parts, such assections of the baleen matrix, the arch of the aorta, plaster casts of the brain,etc., together with the baleen in sitA, were exhibited in the Royal Institutionfor some time, and were ultimately handed over to the Town Council ofEdinburgh. As the skeleton occupied a space of one hundred and twenty feetby forty-five, it was expensive even to afford it house room, and therefore itwas put up at the Zoological Gardens.
