In Bobby’s demonstrations there was neither imagination nor romance: they were merely fascinating in virtue of the amazing exactitude of the detail which his brain had acquired through long familiarity with the dismembered fragments of humanity. There was nothing in the way of minute observation that could escape him, and his questions were so searching and unexpected that even Maskew, who had himself a prodigious memory for minute detail and could carry the letter of a textbook in his head, was constantly floored by them. It was a magnificent stimulus to Edwin; for it became a kind of game to master a part so thoroughly that Bobby could not stump him. By this time he was so used to railway travelling that between the morning discussion of the progress of the war that had just broken out in South Africa, and the appearance of halfpenny papers, that multiplied like greenfly in this heated atmosphere, he could read his text-books of anatomy in a crowded carriage without disturbance apart from the natural curiosity that a vision of luridly coloured diagrams awakened in the minds of his fellow passengers, and particularly the bank clerk, who thirsted in a way that W.G. would have approved for technical instruction in the matter of certain organs. Edwin prepared himself for the demonstrator’s tutorials as rigorously as if he had been approaching a vital examination; he spent long hours in his bedroom, utterly heedless of his wide prospect of wintry fields, thinking of nothing but his collection of bleached bones, now carefully marked with coloured chalks to show the origins and insertions of muscles, and particularly those intricate fretted plates that are joined to form the fragile casket of the human skull. So engrossed was he in absorbing the mere details of their physical form that his mind had no room for other speculations of the kind that had impressed him in the days of his first acquaintance with anatomy. It never struck him that the articulated skull which grinned at him from his mantelpiece when he woke each morning, had once contained the convolutions of a human brain: a mass of pulpy matter that had been the origin of strange complications of movement and feeling and thought, the storehouse of memories, the spring of passions and the theatre of dreams. He did not even know if the skull were that of a man or a woman. To him it was no more than an assembly of dry bones, intricate in their relations with one another, pierced by the foramina of bewildering nerves and blood-vessels, all of which must be visualised and stored and remembered within the limits of another structure of the same kind—the sutures and eminences of which he could feel with his own fingers when he rubbed his puzzled head.
