bequeathed an annuity of one hundred pounds 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 before 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 honor 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 useful to mankind, he shall consult with any other three men of science whose names are a guarantee for probity and knowledge, and according to the best of his judgment, after such consultation, suppress or publish the passage of which he has so doubted. I own the ambition which first directed me towards studies of a very unusual character, and which has encouraged me in their pursuit through many years of voluntary exile in lands where they could be best facilitated or aided the ambition of leaving behind me the renown of a bold discoverer in those recesses of nature which philosophy has hitherto abandoned to superstition. But I feel, at the moment in which I trace these lines, a fear lest, in the absorbing interest of researches which tend to increase to a marvellous degree the power of man over all matter, animate or inanimate, I may have

blunted my own moral perceptions; and that there may be much in the knowledge I sought and acquired from the pure desire of investigating hidden truths, that could be more abused to purposes of tremendous evil than be likely to conduce to benignant good. And of this a mind disciplined to severe reasoning, and uninfluenced by the enthusiasm which has probably obscured my own judgment, should be the unprejudiced arbiter. Much as I have coveted and still do covet that fame which makes the memory of one man the common inheritance of all, I would infinitely rather that my name should pass away with my breath, than that I should transmit to my fellow-men any portion of a knowledge which the good might forbear to exercise and the bad might unscrupulously pervert. I bear about me, wherever I wander, a certain steel casket. I received this casket, with its contents, from a man whose memory I hold in profound veneration. Should I live to find a person whom, after minute and intimate trial of his character, I should deem worthy of such confidence, it is my intention to communicate to him the secret how to prepare and how to use such of the powders and essences stored within that casket as I myself have ventured to employ. Others I have never tested, nor do I know how they could be re-supplied if lost or wasted. But as the contents of this casket, in the hands of any one not duly instructed as to the mode of applying them, would either be useless, or conduce, through inadvertent and ignorant misapplication, to

the most dangerous consequences; so, if I die without having found, and in writing named, such a confidant as I have described above, I command you immediately to empty all the powders and essences found therein into any running stream of water, which will at once harmlessly dissolve them. On no account must they

be cast into fire!

"This letter, Richard Strahan, will only come under your eyes in case the plans and the hopes which I have formed for my earthly future should be frustrated by the death on which I do not calculate, but against the chances of which this will and this letter provide. I am about to revisit England, in defiance of a warning that I shall be there subjected to some peril which I refuse to have defined, because I am unwilling that any mean apprehension of personal danger should enfeeble my nerves in the discharge of a stern and solemn duty. If I overcome that peril, you will not be my heir; my testament will be remodelled; this letter will be recalled and destroyed. I shall form ties which promise me the happiness I have never hitherto found, though it is common to all men - the affections of home, the caresses of children, among whom I may find one to whom hereafter I may bequeath, in my knowledge, a far nobler heritage than my lands. In that case, however, my first care would be to assure your own fortunes. And the sum which this codicil assures to my betrothed would be transferred to yourself on my wedding-day. Do you know why, never

having seen you, I thus select you for preference to all my other kindred? - why my heart, in writing thus, warms to your image? Richard Strahan, your only sister, many years older than yourself—you were then a child — was the object of my first love. We were to have been wedded, for her parents deceived me into the belief that she returned my affection. With a rare and noble candor she herself informed me that her heart was given to another, who possessed not my worldly gifts of wealth and station. In resigning my claims to her hand, I succeeded in propitiating her parents to her own choice. I obtained for her husband the living which he held, and I settled on your sister the dower which, at her death, passed to you as the brother to whom she had shown a mother's love, and the interest of which has secured you a modest independence.

"If these lines ever reach you, recognize my title to reverential obedience to commands which may seem to you wild, perhaps irrational; and repay, as if a debt due from your own lost sister, the affection I have borne to you for her sake."

While I read this long and strange letter, Strahan sat by my side, covering his face with his hands, and weeping with honest tears for the man whose death had made him powerful and rich.

"You will undertake the trust ordained to me in this letter," said he, struggling to compose himself. "You will read and edit this memoir; you are the
