Bonnycastle was a good fellow. He was a tall, gaunt, long-headed man, with large features and spectacles, and a deep, internal voice, with a twang of rusticity in it; and he goggled over his plate, like a horse. I often thought that a bag of corn would have hung well on him. His laugh was equine, and showed his teeth upward at the sides. Wordsworth, who notices similar mysterious manifestations on the part of donkeys, would have thought it ominous. Bonnycastle was passionately fond of quoting Shakspeare, and telling stories; and if the _Edinburgh Review_ had just come out, would give us all the jokes in it. He had once an hypochondriacal disorder of long duration; and he told us, that he should never forget the comfortable sensation given him one night during this disorder, by his knocking a landlord, that was insolent to him, down the man's staircase. On the strength of this piece of energy (having first ascertained that the offender was not killed) he went to bed, and had a sleep of unusual soundness. Perhaps Bonnycastle thought more highly of his talents than the amount of them strictly warranted; a mistake to which scientific men appear to be more liable than others, the universe they work in being so large, and their universality (in Bacon's sense of the word) being often so small. But the delusion was not only pardonable, but desirable, in a man so zealous in the performance of his duties, and so much of a human being to all about him, as Bonnycastle was. It was delightful one day to hear him speak with complacency of a translation which had appeared of one of his books in Arabic, and which began by saying, on the part of the translator, that "it had pleased God, for the advancement of human knowledge, to raise us up a Bonnycastle." Some of his stories were a little romantic, and no less authentic. He had an anecdote of a Scotchman, who boasted of being descended from the Admirable Crichton; in proof of which, the Scotchman said he had "a grit quantity of table-leenen in his possassion, marked A. C., Admirable Creechton."
