Penchant for Stock Revealed by Will

For thirty years Dr. Mack J. Seeley, 82, one of California's oldest practicing dentists, purchased stock, much of it worthless, it was revealed yesterday with the filing of his will and that of his wife, Lizzie H. Seeley, 79. She died May 25, four weeks after he was stricken. The aged couple drew up their wills on August 9, 1894, naming each other beneficiaries. There are thousands of certificates, probably worth only a few thousand dollars. The money will go to a niece in New York.
