His biographer remarks: "Only once, as far as I can learn, did Knox exhibit any emotion on account of the connection of his name with the Burke and Hare atrocities, and his freely-alleged complicity in the transaction. Walking in the meadows at Edinburgh with his old friend Dr. Adams, their conversation turned upon 'outward form and its relation to inward qualities.' Knox had a keen appreciation of the beautiful in form; and it chanced at the moment that a pretty little girl, about six years of age, caught his notice while at play. She afforded a text for Knox's comment on physical beauty, combined with unusual intelligence, in so young a child, for by this time he had drawn her into a playful conversation. At length he gave her a penny, and said: 'Now, my dear, you and I will be friends. Would you come and live with me if you got a whole penny every day?' 'No,' said the child; 'you would, maybe, sell me to Dr. Knox.' The anatomist started back with a painfully stunned expression; his features began to twitch convulsively, and tears appeared in his eyes. He walked hastily on, and did not exchange words with Dr. Adams for some minutes; at length came a forced laugh, with a questionable emphasis on the words 'vox populi', which led to a new topic of discourse."
Dr. Knox gave up his lectures in Edinburgh in 1839, and afterward went to London, where he died, December 20, 1862.
| TEMPERED GLASS. |
By PERRY F. NURSEY, C. E.
A CONSIDERABLE degree of well-merited attention has of late been directed toward an invention which may be justly termed remarkable, even in these days of startling discoveries, inasmuch as it is one which promises to effect a complete change in the physical character of glass. This invention is the toughening process of M. François Royer de la Bastie, by which the natural brittleness of ordinary glass is exchanged for a condition of extreme toughness and durability. And this invention is perhaps the more remarkable in that it does not emanate from one engaged in, or practically conversant with, the manufacture of glass; nor is the discovery due to one of the great lights of science of our day; neither was it the result of a happy momentary inspiration. On the contrary, M. de la Bastie is a French private gentleman of fortune, residing in his native country—who, however, is given to the study of scientific matters. He was educated as an engineer, but his position and means rendered it unnecessary for him to follow the profession into which he had been initiated. He, however, is fond of experimenting in matters relating to engineering, and among
