There is, however, another section of the zoological department of the museum which owes its conception entirely to Sir William Flower, and which he was fortunately spared to complete. This is the whale-room, or whale-annexe, as it might be better called; for it is a temporary structure of galvanised iron, lined with match-boarding built out from the north-west angle of the building, and entered by a passage leading out of the corridor alongside the bird gallery. At the time that Flower took over the Keepership of the Zoological Department, with the exception of a skeleton of the sperm-whale, placed in the middle of the Central Hall, the specimens of Cetacea were housed in a portion of the basement, never intended for a public gallery and very unsuited to that purpose. The collection consisted mainly of skeletons and skulls, together with samples of whalebone and teeth; for it had been found by experience that it was a practical impossibility to mount the skins of the larger whales for exhibition purposes. Indeed, there is great difficulty in doing this even in the case of the dolphins, porpoises, and smaller whales, owing to the fact that their skins are saturated with oil, which, even after the most careful preparation, is almost sure, sooner or later, to exude through the pores, and render the specimens unsightly, if not absolutely unfit for exhibition. Previously to Flower’s attempt to make an adequate and striking exhibition of the bodily form of the larger whales, some of the smaller members of the group, such as the killer-whale, had been modelled in America in papier-maché; one such model of the species in question being exhibited in the museum. Flower, however, conceived the idea of making models in plaster of even the largest species of whales; but, in order to save both material and space, resolved that these should be restricted to one-half of the animal, and should be constructed upon the actual skeleton, thereby ensuring, with the aid, when possible, of measurements taken from carcases, practically absolute accuracy as regards size and proportion. In due course, after great labour and care, such half-models were built up on the skeletons of the sperm-whale, the southern right-whale, and two species of fin-whale, or rorqual, while others were made of some of the smaller kinds, such as the narwhal and the beluga or white whale. Skeletons and skulls of other species, together with complete models or stuffed skins, or models of the head alone, of many of the porpoises and dolphins, and other specimens illustrating the natural history of the Cetacea, were likewise placed in the new annexe, which was opened to the public on Whit Monday 1897. Flower had always been impressed with the great structural difference between the toothed whales, as represented by the sperm-whale, grampuses, porpoises, dolphins, etc., on the one hand, and the whalebone-whales, such as the right-whales, humpbacks, and finners, on the other; and in order to
