On his appointment to the Conservatorship of the Museum of the College of Surgeons, Flower once for all definitely abandoned medicine as a profession, and determined to devote the whole of his energies for the future to the study of his beloved comparative anatomy and zoology. Nevertheless, he always remained in touch with his old profession, as he was always in sympathy with those who were actively practising the same. Indeed, since the collections under his charge included a large pathological series, while during his tenure of office a large display of surgical instruments was added to the exhibits, he could not, even had he so desired, cut himself entirely adrift from old associations and old studies. Since a considerable amount of space in a later chapter is devoted to Flower’s work as Museum Curator and as Hunterian Lecturer, it will be unnecessary to allude further to it in this place, although it will be appropriate to quote the elogium on his efforts in this sphere, pronounced by the President of the Royal Society, when bestowing the Royal Gold Medal in recognition of his services to zoology. “It is very largely due,” runs the address, “to his incessant and well-directed labour that the museum of the Royal College of Surgeons at present contains the most complete, the best ordered, and the most accessible collection of materials for the study of vertebrate structures extant.” As regards his Hunterian lectures, it has been well remarked that few could have any idea of the amount of labour they involved, nor would any one be likely to guess this from the ever-ready and earnest efforts of the lecturer to give to others that knowledge he had so laboriously, and yet so pleasantly, acquired within the walls of the museum. In addition to the official Hunterian lectures, Flower during this portion of his career commenced the delivery, as opportunity occurred, of lectures of a much more popular description, at the Royal Institution and elsewhere, by means of which he appealed to a wider audience than any that could be attracted to technical discourses, and at the same time was enabled to give a wide circulation to the discussion of subjects connected with his own special studies which had more or less of a general interest. In one of his earlier discourses of this type he discussed at considerable detail the deformities produced in the human foot by badly-designed boots or other covering among both civilised and barbarous nations. Indeed, “fashion in deformity” was at all times a favourite theme with the Hunterian Professor; and in a lecture on this subject he uttered, for him, a strong protest against the evils caused by the corset among European females, illustrating his remarks with a ghastly figure of a female skeleton distorted by the undue pressure of that fashionable article of costume.
