In connection with this series may be mentioned the fact that Flower published during the year he took office the work which heads the list of his numerous scientific contributions, namely, _Diagrams of the Nerves of the Human Body, exhibiting their Origin, Divisions and Connections_, which was favourably received by the medical profession. In the preparation of the anatomical series, Flower’s almost unrivalled powers of dissection stood him in good stead, and it was probably during this period of his career that he first acquired the rudiments of that originality and care in museum arrangement and display that led to his being called in after life by a German savant “the Prince of Museum Directors.” Perhaps, however, the portion of the museum under his charge in which Flower was most deeply interested was that devoted to the dentition and osteology of the different orders of the Mammalia. As regards the osteological series, he expressed himself in the above-mentioned address of 1881 in the following words:— “On this head we claim to be somewhat in advance of other museums, on account of the improvements which have been made of late years in preparing and articulating dried skeletons, and in displaying portions of the bony framework in an instructive manner. Formerly all the bones were rigidly fixed together, so that their articular surfaces, if not actually destroyed, were completely concealed, and no bone could possibly be removed and separately examined. The aim of a series of changes in the method of mounting skeletons introduced here, and now adopted, more or less completely, in many other museums, has been to obviate all these difficulties, and to make each bone, as far as possible, independent of all the rest, whilst preserving the general aspect and form of the entire skeleton. “Another improvement in the osteological series introduced within the last twenty years has been the formation of a special collection designed to show the principal modifications of each individual skeleton throughout the vertebrate classes, by the placing the homologous bones of a number of different animals in juxtaposition. For convenience of comparison, the specimens of this series are all placed in corresponding positions, mounted on separate stands, and to each is attached a label bearing the name of the bone and the animal to which it belongs. This series is especially instructive to the students of elementary osteology, and forms an introduction to the general series.”
