12 Jan [1874]

    Summary Add

    CD requests WW to ask a large breeder of greyhounds whether the increase in litters requires that some puppies be destroyed. If so, is it sufficient to destroy merely the small and weak? Would this result in more males or females being destroyed?

  • +

    CD once used the Field to tabulate ratios of female to male births in greyhounds (110: 100).
