Item 8 - Autograph letter, signed, from Coleman Miller (aged 7 ¼), Reading, Michigan, to FH

Likes reading FH's book Highlights of astronomy, but disagrees with FH's opinions on the effect that lower gravity would have on life on earth. FH says that birds would become the dominant life forms if gravity much less, but Cole believes that land animals would also become much greater in the mass, and that they would grow twice as tall.
