is merely a hypothesis, without proof of any sort, but in a case so extraordinary every suggestion may be of value. The Rosicrucians, to whom allusion is made in this paper, were the most profound chemists of the early Middle Ages, and included the principal alchemists whose names have descended to us. Much as chemistry has advanced, there are some points in which the ancients were ahead of us, and in none more so than in the manufacture of poisons of subtle and deadly action. This man Bodeck, as one of the elders of the Rosicrucians, possessed, no doubt, the recipe of many such mixtures, some of which, like the aqua tofana of the Medicis, would poison by penetrating through the pores of the skin. It is conceivable that the handle of this silver hatchet has been anointed by some preparation which is a diffusible poison, having the effect upon the human body of bringing on sudden and acute attacks of homicidal mania. In such attacks it is well known that the madman's rage is turned against those whom he loved best when sane. I have, as I remarked before, no proof to support me in my theory, and simply put it forward for what it is worth."
