surprise at the point of view of some naturalists: "They admit that a multitude of forms, which till lately they themselves thought were special creations,...have been produced by variation, but they refuse to extend the same view to other and very slightly different forms...They admit variation as a vera causa in one case, they arbitrarily reject it in another, without assigning any distinction in the two cases. The day will come when this will be given as a curious illustration of the blindness of preconceived opinion.") it is very false to say that I imply by "blindness of preconceived opinion" the simple belief of creation. And so on in other cases. But I beg pardon for troubling you. I am heartily sorry that in your unselfish endeavours to spread what you believe to be truth, you should have incurred so brutal an attack. (98/6. The "Edinburgh" Reviewer, referring to Huxley's Royal Institution Lecture given February 10th, 1860, "On Species and Races and their Origin," says (page 521), "We gazed with amazement at the audacity of the dispenser of the hour's intellectual amusement, who, availing himself of the technical ignorance of the majority of his auditors, sought to blind them as to the frail foundations of 'natural selection' by such illustrations as the subjoined": And then follows a critique of the lecturer's comparison of the supposed descent of the horse from the Palaeothere with that of various kinds of domestic pigeons from the Rock-pigeon.) And now I will not think any more of this false and malignant attack.
LETTER 99. TO MAXWELL MASTERS. Down, April 13th [1860].
I thank you very sincerely for your two kind notes. The next time you write to your father I beg you to give him from me my best thanks, but I am sorry that he should have had the trouble of writing when ill. I have been much interested by the facts given by him. If you think he would in the least care to hear the result of an artificial cross of two sweet peas, you can send the enclosed; if it will only trouble him, tear it up. There seems to be so much parallelism in the kind of variation from my experiment, which was certainly a cross, and what Mr. Masters has observed, that I cannot help suspecting that his peas were crossed by bees, which I have seen well dusted with the pollen of the sweet pea; but then I wish this, and how hard it is to prevent one's wish biassing one's judgment!
I was struck with your remark about the Compositae, etc. I do not see that it bears much against me, and whether it does or not is of course of not the slightest importance. Although I fully agree that no definition can be drawn between monstrosities and slight variations (such as my theory requires), yet I suspect there is some distinction. Some facts lead me to think that monstrosities supervene generally at an early age; and after attending to the subject I have great doubts whether species in a state of nature ever become modified by such sudden jumps as would result from the Natural Selection of monstrosities. You cannot do me a greater service than by pointing out errors. I sincerely hope that your work on monstrosities (99/1. "Vegetable Teratology," London, 1869 (Ray Soc.).) will soon appear, for I am sure it will be highly instructive.
Now for your notes, for which let me again thank you.
1. Your conclusion about parts developed (99/2. See "Origin of Species," Edition I., page 153, on the variability of parts "developed in an extraordinary manner in any one species, compared with the other species of the same genus." See "Life and Letters," II., pages 97, 98, also Letter 33.) not being extra variable agrees with Hooker's. You will see that I have stated that the rule apparently does not hold with plants, though it ought, if true, to hold good with them.
2. I cannot now remember in what work I saw the statement about Peloria affecting the axis, but I know it was one which I thought might be trusted. I consulted also Dr. Falconer, and I think that he agreed to the truth of it; but I cannot now tell where to look for
