to return to Malvern. In 1856, he began writing for publication of his theory, and he pressed on, overworking, until by March 1857 illness was cutting his working day "ridiculously short". He found a new hydrotherapist, Dr. Edward Wickstead Lane, whose Moor Park hydropathic establishment near Farnham in Surrey was only 40 miles from Darwin's home. His condition was much as when Darwin had first seen Gully, and Dr. Lane later wrote, "I cannot recall any [case] where the pain was as poignant as his. When the worst attacks were on, he seemed crushed with agony." Darwin arrived on 22 April and wrote to Fox that "it is really quite astonishing & utterly unaccountable the good this one week has done me", deciding to stay on to 5 May. He enjoyed the more relaxed regime, which did not include clairvoyance, mesmerism or homeopathy, as Lane did "not believe in all the rubbish which Dr G. does." Darwin became a complete convert, "well convinced that the only thing for Chronic cases is the water-cure", and wrote, "I really think I shall make a point of coming here for a fortnight occasionally, as the country is very pleasant for walking." He told Hooker he had "already received an amount of good, which is quite incredible to myself & quite unaccountable.—I can walk & eat like a hearty Christian; & even my nights are good.—I cannot in the least understand how hydropathy can act as it certainly does on me. It dulls one's brain splendidly, I have not thought about a single species of any kind, since leaving home." He then contradicted himself by asking about alpine species. He returned to Moor Park from 16 to 29 June and 5–12 November 1857 and from 20 April to 3 May 1858, but this retreat was unavailable when he was shocked by receipt of Wallace's paper on 18 June, as Dr. Lane was put on trial accused of adultery with a lady patient. Darwin was able to resume treatment at Moor Park from 25 to 31 October 1858, as he struggled on to write On the Origin of Species despite repeated health problems. He was able to keep writing thanks to visits to the spa on 5–18 February, 21–28 May and 19–26 July 1859. With the proofs of the book returned to the printers, he was worn out. On 2 October, he left for Ilkley
