"I'll come presently," said Henry; "I really want to hear this." Henry Campbell was not listening to the history of the lady's favourite birds like a polite hypocrite, but like a good-natured sensible person; the circumstances recalled to his memory the conversation that we formerly mentioned, which began about pickled cucumbers, and ended with Dr. Campbell's giving an account of the effects of some poisons. In consequence of this conversation, Henry's attention had been turned to the subject, and he had read several essays, which had informed him of many curious facts. He recollected, in particular, to have met with the account{2} of a bird that had been poisoned, and whose case bore a strong resemblance to the present. He begged leave to examine the cage, in order to discover whether there were any lead about it, with which the birds could have poisoned themselves. No lead was to be found: he next examined whether there were any white or green paint about it; he inquired whence the water came which the birds had drunk; and he examined the trough which held their seeds. The lady, whilst he was pursuing these inquiries, said she was sure that the birds could not have died either for want of air or exercise, for that she often left the cage open on purpose, that they might fly about the room. Henry immediately looked round the room, and at length he observed in an inkstand, which stood upon a writing table, a number of wafers, which were many of them chipped round the edges; upon sweeping out the bird-cage, he found a few very small bits of wafer mixed with the seeds and dust; he was now persuaded that the birds had eaten the wafers, and that they had been poisoned by the red lead which they contained; he was confirmed in this opinion, by being told, that the wafers had lately been missed very frequently, and it had been imagined that they had been used by the servants. Henry begged the lady would try an experiment, which might probably save the life of her new favourite; the lady, though she had never before tried an experiment, was easily prevailed upon. She promised Henry that she would lock up the wafers; and he prophesied that her bird would not, like his predecessors, come to an untimely end. Archibald Mackenzie was vexed to observe, that knowledge had in this instance _succeeded_ better, even with a lady, than flattery. As for Forester, he would certainly have admired his friend Henry's ingenuity, if he had been attending to what had passed; but he had taken a book, and had seated himself in an arm-chair, which had been placed on purpose for an old gentleman in company, and was deep in the history of a man who had been cast away, some hundred years ago, upon a desert island. {Footnote 2: Falconer, on the Poison of Lead and Copper.}
