The validly executed will of John Dane contained the following provision: ‘‘I give and devise to my daughter, Mary, Redacre for and during her natural life and, at her death, the remainder to go to Wilmore College.’’ The will also provided that the residue of his estate should go to Wilmore College. Thereafter, Dane sold Redacre and then added a validly executed codicil to his will, ‘‘Due to the fact that I have sold Redacre which I previously gave to my daughter, Mary, I now give and devise Blackacre to Mary in place and instead of Redacre.’’
Another clause of the codicil provided: ‘‘I give to my son, Henry, my one-half interest in the oil business, which I own in common with William Steele.’’ Subsequently, Dane acquired all of the interest in the oil business from his partner, Steele, and, at the time of his death, Dane owned the entire oil business. The will and codicil have been admitted to probate.
