The will in Mr. Jeeves's keeping, with its recent codicil, was opened and read. The will itself bore date about six years anterior to the testator's tragic death: it was very short, and, with the exception of a few legacies, of which the most important was L10,000 to his ward, the whole of his property was left to Richard Strahan, on the condition that he took the name and arms of Derval within a year from the date of Sir Philip's decease. The codicil, added to the will the night before his death, increased the legacy to the young lady from L10,000 to L30,000, and bequeathed an annuity of L100 a year to his Albanian servant. Accompanying the will, and within the same envelope, was a sealed letter, addressed to Richard Strahan, and dated at Paris two weeks be fore Sir Philip's decease. Strahan brought that letter to me. It ran thus:-- "Richard Strahan, I advise you to pull down the house called Derval Court, and to build another on a better site, the plans of which, to be modified according to your own taste and requirements, will be found among my papers. This is a recommendation, not a command. But I strictly enjoin you entirely to demolish the more ancient part, which was chiefly occupied by myself, and to destroy by fire, without perusal, all the books and manuscripts found in the safes in my study. I have appointed you my sole executor, as well as my heir, because I have no personal friends in whom I can confide as I trust I may do in the man I have never seen, simply because he will bear my name and represent my lineage. There will be found in my writing-desk, which always accompanies me in my travels, an autobiographical work, a record of my own life, comprising discoveries, or hints at discovery, in science, through means little cultivated in our age. You will not be surprised that before selecting you as my heir and executor, from a crowd of relations not more distant, I should have made inquiries in order to justify my selection. The result of those inquiries informs me that you have not yourself the peculiar knowledge nor the habits of mind that could enable you to judge of matters which demand the attainments and the practice of science; but that you are of an honest, affectionate nature, and will regard as sacred the last injunctions of a benefactor. I enjoin you, then, to submit the aforesaid manuscript memoir to some man on whose character for humanity and honour you can place confidential reliance, and who is accustomed to the study of the positive sciences, more especially chemistry, in connection with electricity and magnetism. My desire is that he shall edit and arrange this memoir for publication; and that, wherever he feels a conscientious doubt whether any discovery, or hint of discovery, therein contained would not prove more dangerous than
