With the growing popularity of South Kensington Museum the directors and curators of its priceless collections have increased their efforts to adapt some of the accumulated store of knowledge which those collections represent to popular comprehension. The results of this activity have of late become manifest, both in the great Central Hall, and in the incomparable collection of British birds. The birds, which have been for many years a dull assemblage of specimens, all stuffed alike, and bearing an unnatural common resemblance to one another, are being rearranged in cases with a proper environment of rocks and shrub, sandhill or marsh; and with a skillful and successful attempt to display them in their habitat as they live. The work is not nearly complete; it will hardly be so for two years to come; but already some of the cases, especially those of the solan geese, the eagles, the cormorants, and the almost vanished British bustard, are most interesting and beautiful object lessons in natural history. A lesson of a different kind is being begun in the Central Hall. During the period of Sir William Flower's directorship a number of specimens of canaries, pigeons, and domestic fowl were collected, and it was sought to show by means of these the variations which breeding might produce on a single type. Two cases of these specimens now stand in the Central Hall. On the top of the "pigeon exhibit" is the common rock pigeon. Below him, tier upon tier, are ranged the carriers, tumblers, pouters--the thirty odd breeds which fanciers have produced from the original ancestors. Many of these specimens were prize-winners in their day.
