[Letters to Editor] | Nature

I HAVE not changed any of my views; but Mr. Dixon appears to change his within the limits of two consecutive sentences. For, immediately after his strong protest against my statement that he

has attempted to explain the causes of variation, he complains of my want of fairness in not acknowledging the adequacy of the “evolutionistic agents” which he has suggested as “the causes

of variation.” With this specimen of Mr. Dixon's method of discussion before them, your readers may be able to sympathise with the failure which seems to have attended my efforts at

expounding his essay.
