Neither did Nobs resemble in his taste that remarkable horse which Dr. Tyson frequently saw in London at the beginning of the last century. This horse would eat oysters with great delight, scrunching them shells and all between his teeth. Accident developed in him this peculiar liking; for being fastened one day at a tavern-door where there happened to be a tub standing with oysters in it, the water first attracted him, and then the fresh odour of fish induced him to try his teeth upon what promised to be more savoury than oats and not much harder than horse-beans. From that time he devoured them with evident satisfaction whenever they were offered him; and he might have become as formidable a visitor to the oyster-shops, if oyster-shops there then had been, as the great and never-to-be-forgotten Dando himself. He was not like the Colt which Boyle describes, who had a double eye, that is to say two eyes in one socket, in the middle of his forehead, a Cyclops of a horse. Nor was he like the coal-black steed on which the Trappist rode, fighting against the _Liberales_ as heartily as that good Christian the Bishop Don Hieronimo fought with the Cid Campeador against the Moors, elevating the Crucifix in one hand, and with his sword in the other smiting them for the love of Charity. That horse never needed food or sleep: he never stumbled at whatever speed his master found it needful to ride down the most precipitous descent; his eyes emitted light to show the Trappist his way in the darkness; the tramp of his hoofs was heard twenty miles around, and whatsoever man in the enemy's camp first heard the dreadful sound, knew that his fate was fixed, and he must inevitably die in the ensuing fight. Nobs resembled this portentous horse as little as the Doctor resembled the terrible Trappist. Even the great black horse which used to carry old George, as William Dove called the St. George of Quakerdom, far exceeded him in speed. The Doctor was never seen upon his back in the course of the same hour at two places sixty miles apart from each other. There was nothing supernatural in Nobs. His hippogony, even if it had been as the Doctor was willing to have it supposed he thought probable, would upon his theory have been in the course of nature, though not in her usual course.
