but Emma and the children continued to attend services. On Sundays Darwin sometimes went with them as far as the lych gate to the churchyard, and then he would go for a walk. During the service, Emma continued to face forward when the congregation turned to face the altar for the Creed, sticking to her Unitarian faith. Death of Annie At the end of June 1850 his bright nine-year-old daughter Annie who had become a particular favourite and comfort to him fell sick and, after a painful illness, died on 23 April 1851. During Annie's long illness Darwin had read books by Francis William Newman, a Unitarian evolutionist who called for a new post-Christian synthesis and wrote that "the fretfulness of a child is an infinite evil". Darwin wrote at the time, "Our only consolation is that she passed a short, though joyous life." For three years he had deliberated about the Christian meaning of mortality. This opened a new vision of tragically circumstantial nature. His faith in Christianity had already dwindled away and he had stopped going to church. He wrote out his memories of Annie, but no longer believed in an afterlife or in salvation. Emma believed that Annie had gone to heaven and told this to the children, with the unfortunate result that Henrietta wondered, "If all the angels were men, did women go to heaven?" She worried for months that her naughtiness while Annie was alive would mean that she would go to hell unless God forgave her. On the Origin of Species Darwin continued to avoid public controversy and to accumulate evidence supporting his theory against the anticipated arguments. In 1858 the information that Alfred Russel Wallace now had a similar theory forced an early joint publication of Darwin's theory. The reaction to Darwin's theory, even after publication of On the Origin of Species in 1859, was more muted than he had feared. One of the first responses to review copies came from Charles Kingsley, a Christian socialist country rector and novelist, who wrote that it was "just as noble a conception of Deity, to believe that He created primal forms capable of self development... as to believe that He required a fresh act of intervention to supply the lacunas which He Himself had made." For the second edition, Darwin added these lines to the last chapter, with attribution to "a celebrated author and divine".
