In 1839, now married to Emma and settled in London, Darwin continued to look to the countryside for information and began a "Questions & Experiments" notebook with ideas that would have seemed bizarrely mundane to the "philosophical" scientists of the time. He printed "Questions about the Breeding of Animals" and sent them out to gentlemen farmers, asking for information on animal husbandry from their nurserymen and gamekeepers on how they crossed varieties or selected offspring. Of only three who responded one simply found the questions too overwhelming to answer. He found agreement with the visiting Swiss botanist Alphonse de Candolle whose father Augustin had used the idea of "nature's war". However, when he tried explaining his theory to Hensleigh Wedgwood, his cousin "seemed to think it absurd... that tiger springing an inch further would determine his preservation".
