“9. In case any of the children of the said Arthur Hugh Clough, the father, or of the said William Shore Nightingale shall die in my lifetime, then I give and bequeath the legacy, or legacies (specific or pecuniary) hereinbefore given to such child, to his or her children (if any) who shall be living at my death and if more than one in equal shares. “10. I devise and bequeath all the residue of my personal estate and effects whatsoever and wheresoever and all my real estate of every tenure and wheresoever situate unto and to the use of the children of the said William Shore Nightingale who shall be living at my death, and the child or children then living of any deceased child of his absolutely, and if more than one in equal shares, but so that the children of any deceased child of his shall take equally between them only the share which their parent would have taken had he or she survived me. “11. I authorize my executors to determine what articles pass under any specific bequest contained in this my Will or any Codicil hereto and to determine all questions and matters of doubt arising under this my Will or any Codicil hereto. And I declare that every such determination, whether made upon a question actually raised or implied in the acts or proceedings of my executors, shall be conclusive and binding on all persons interested under this my Will. And I declare that all powers, authorities and discretions thereby expressed to be vested in or given to my executors shall be vested in and exercisible by the acting executors or executor for the time being of this my Will. And I declare that my executors may employ the said Louis Hilary Shore Nightingale professionally, if they think proper, and that if so employed he shall be entitled to charge and be paid all usual professional or other charges for any business done by him and whether in the ordinary course of his profession or business or not. “12. I give my body for dissection or postmortem examination for the purposes of Medical Science and I request that the directions about my funeral given by me to my uncle, the late Samuel Smith, be observed; my original request was that no memorial whatever should mark the place where lies my ‘Mortal Coil.’ I much desire this but should the expression of such wish render invalid my other wishes, I limit myself to the above mentioned directions, praying that my body may be carried to the nearest convenient burial ground, accompanied by not more than two persons without trappings and that a simple cross, with only my initials, date of birth and of death, mark the spot.
