'A great deal more was said, which I do not feel called upon to repeat. Poor David T. departed in a charming state of conglomeration, and he confessed to my brother, to whom, under the seal of profound secrecy, he reported the whole conversation, that when he left the Colonel's house he scarcely knew whether he was standing on his head or his heels. My brother, after indulging in a hearty laugh, asked him if he had yet paid one visit recommended to him. "No," said David, "I'll take care how I do that!" "But, then," returned my brother, "you won't be able to see Colonel MacC. again." "No," replied David, "I'll take care how I do that, too!" 'David T. was in many respects a very good fellow, but he took everything literally, and actually had, I believe, a sort of horror at a joke, particularly if he did not understand it, which was commonly the case. He was not a fire-eating Irishman, or he would have rivalled Sir Brallaghan O'Callaghan in the play, who says, "And if you shall say anything that I will not understand," etc. David, however, did not resort to the _ultima ratio_ when he did not understand; he waited to have the joke explained. He had, perhaps, never heard that wit explained is no longer wit; but, whether he had or not, neither the wit nor the explanation ever seemed to disorder his equanimity. The only witty story I ever heard him tell, was one of Professor B., who was one of David's masters when attending the classes at Edinburgh. This gentleman was in the habit of enlivening his lectures by asking questions of his pupils. He had, on the occasion under reference, been using some mechanical illustrations to show that if the spring of a machine be wound up too tight, the whole apparatus will go too fast, unless a counterbalancing force be brought into play. Thus if the weights are not sufficient, the clock goes too fast; and on the other hand, if the weights are too great, the clock stops, or goes too slow. In the more perfect arrangements, a pendulum supersedes the weights, and can be lengthened or shortened to produce like effects. "Similar laws," said the Professor, "obtain in morals and in physics. If a youth is going too fast you put him under restrictions--in other words, you put more weight on him, and _vice versâ_. Now," turning round to one of the students, he said, "if you found a youth who was under your charge, a younger brother, for instance, not going quick enough, in fact--going decidedly too slow, what would you do?" "I wad shorten his pend'lum, sir," replied the unlucky wight. Here roars of laughter put an end to the sentence and the lecture; as this little anecdote puts an end to our further knowledge of David, who was a steady and solid practitioner of medicine, painstaking and zealous in his duty, a good husband, a good father, and a good Presbyterian. He died of cholera, poor fellow! at Trichinopoly, lamented by all who knew him, except the snipes, who certainly must have
