CID7 (2) with biometric work and all that it means for biology than I am. The only ground, so far as I can see, for a difference of opinion between you and me and the ground for which it seems to me I am really removed from the editorial staff of Biometrika, is simply this: That I do not and cannot believe in the law of ancestral inheritance in the light of the facts as I see them in experimental breeding work. We are all liable to mistakes, both in matters of fact and in matters of judgment, but I must say that it is my settled conviction that the law of ancestral inheritance as you have developed it in your work has absolutely no relation to the essential facts of inheritance as they exist in plants and animals. I think that you must know me well enough to know that this is not a conclusion which I have reached from superficial evidence or from a slight acquaintance with the facts. It is a conclusion which I have been most reluctant in reaching, but which at the same time I believe with every fiber of my intellectual being to be essentially correct. This is a matter, however, which time and research will settle and settle definitely. The immediate point is, it seems to me, that I am removed from the editorial staff of Biometrika simply on the grounds of a difference of opinion regarding a controverted question still under investigation in biology. In other words, it seems to me that by the adoption of this policy you are definitely announcing to the scientific public that you propose to have no one associated with you in the editorship of Biometrika who does not think exactly as you do on the questions of theoretical biology. I must say that it seems to me that such an attitude is a mistake both immediately [end]
