I send the [English] translation of Bronn (A MS. translation of Bronn's chapter of objections at the end of his German translation of the 'Origin of Species.'), the first part of the chapter with generalities and praise is not translated. There are some good hits. He makes an apparently, and in part truly, telling case against me, says that I cannot explain why one rat has a longer tail and another longer ears, etc. But he seems to muddle in assuming that these parts did not all vary together, or one part so insensibly before the other, as to be in fact contemporaneous. I might ask the creationist whether he thinks these differences in the two rats of any use, or as standing in some relation from laws of growth; and if he admits this, selection might come into play. He who thinks that God created animals unlike for mere sport or variety, as man fashions his clothes, will not admit any force in my argumentum ad hominem. Bronn blunders about my supposing several Glacial periods, whether or no such ever did occur. He blunders about my supposing that development goes on at the same rate in all parts of the world. I presume that he has misunderstood this from the supposed migration into all regions of the more dominant forms. I have ordered Dr. Bree ('Species not Transmutable,' by C.R. Bree, 1860.), and will lend it to you, if you like, and if it turns out good. ... I am very glad that I misunderstood you about species not having the capacity to vary, though in fact few do give birth to new species. It seems that I am very apt to misunderstand you; I suppose I am always fancying objections. Your case of the Red Indian shows me that we agree entirely... I had a letter yesterday from Thwaites of Ceylon, who was much opposed to me. He now says, "I find that the more familiar I become with your views in connection with the various phenomena of nature, the more they commend themselves to my mind." CHARLES DARWIN TO J.M. RODWELL. (Rev. J.M. Rodwell, who was at Cambridge with my father, remembers him saying:--"It strikes me that all our knowledge about the structure of our earth is very much like what an old hen would know of a hundred acre field, in a corner of which she is scratching.") 15 Marine Parade, Eastbourne. November 5th [1860]. My dear Sir,
