The last will and testament of Nancy Clarke Bache is as follows: 
I hereby, in pursuance and exercise of the power of appointment contained in the last 
will and testament of my husband, Alexander Dallas Bache, devise, bequeath, and appoint 
the sum of five thousand dollars of the principal of the estate of my said husband, over 
which I have a power of appointment by his will, to be paid by his executors, or by such 
person or persons as shall hold the principal of the estate at my death, to my nephew, 
Henry Wood Bache, absolutely; and I hereby request my nephew, in case he should die 
unmarried and without issue, to make such a disposition of this amount by will as will secure 
it to be paid at his death to the National Academy of Sciences, at Washington, to be held 
by that corporation upon the same trusts and for the same purposes as are declared by my 
husband in his will as to the residue of his estate after my death. I expressly desire, 
however, that it shall be understood that this request shall not be construed into any 
direction which would interfere with his full control of the principal, which is to be paid 
into his hands directly.
