"In saying that my patient is a lucky man in being able to get away from Ichaboe, you never spoke truer words in your life, Jasper Ivory. But you are wrong if you imagine that we are such ignoramuses as to attribute his illness to what you are pleased to call the infernal climate. Infernal climate, forsooth! But I am forgetting that you are a layman, liable, now and then, to express yourself inaccurately, and, of course, totally ignorant in the matter of diseases or drugs--particularly poisons. I may tell you, therefore, that the initial cause of Mr. Lees' malady has been traced to one of the precious pack of rascals whom he had to keep in order here. I suppose a simple seaman like you has never seen any seeds like these before? I found them in the locker of Daniel White, late steward of the _Elora_--a man who, curiously enough, was an old friend of yours." The doctor, as he said these words, took a number of claret-coloured seeds out of his waist-coat pocket and held them out on the palm of his hand for Captain Ivory's inspection, closely watching his face the while. But not a muscle moved; and it was with absolute control over both voice and features that Jasper replied, nonchalantly:-- "What a beautiful colour! And what may be the name of those pretty things, doctor? I rely on your superior knowledge, which appears to cover a wider field than science, since you've just made me the friend of a man of whom I've never heard in my life." "We scientists call them the seeds of _Physostigma venenosum_; but they are known amongst you sailors as Calabar beans. Considering that there isn't a mariner cruising on the West Coast of Africa who doesn't know them, your education appears to have been singularly neglected. However, Daniel White will be able to complete it for you when the _Gurango_ rejoins the _Florentia_, on which ship--for the time being, at any rate--he escaped from justice." At this Captain Jasper could preserve his self-possession no longer. "So you persist in coupling your confounded steward with me and my ships, do you?" he said, hotly. "Then let me tell you that you can talk enigmas and concoct your inventions until you are black in the face. I don't care _that_ for them," snapping his fingers; "and I'll see you all three in Hades before you'll get another civil word from me!" In a flash he had left them and was out on deck, where he continued to vent his anger by a torrent of oaths. Dr. Maxwell and the captain of the _Elora_ watched him with aggravating coolness as he was being rowed away, a sullen, malicious look in his eyes. "His face was a study for a criminologist," was the doctor's pregnant comment on returning to the cabin. Lees saw no more of Ivory before the _Elora_ set sail for St. Helena, but he had not yet finished with that remarkable man; and so dramatic and unexpected was his next meeting with his enemy to be, that its every circumstance remained fresh in his mind to the day of his death.
