The press marked E was unlocked; and I took out the drawer, had it filled up with straw and tied in a sheet, and returned with it to Cavendish Square. Here I proceeded to examine its contents. The powders were neatly enough made up, but not with the nicety of the dispensing chemist; so that it was plain they were of Jekyll’s private manufacture; and when I opened one of the wrappers I found what seemed to me a simple crystalline salt of a white colour. The phial, to which I next turned my attention, might have been about half full of a blood-red liquor, which was highly pungent to the sense of smell and seemed to me to contain phosphorus and some volatile ether. At the other ingredients I could make no guess. The book was an ordinary version book and contained little but a series of dates. These covered a period of many years, but I observed that the entries ceased nearly a year ago and quite abruptly. Here and there a brief remark was appended to a date, usually no more than a single word: “double” occurring perhaps six times in a total of several hundred entries; and once very early in the list and followed by several marks of exclamation, “total failure!!!” All this, though it whetted my curiosity, told me little that was definite.
