I have to drive with all my might, and am not yet clear, though I trust the worst is past. I get so fagged that when I sit down to Darwin’s “Insectivorous Plants,” by way of relaxation, of an evening, I fall asleep over it. And so have not finished that book yet, as it cannot be read with the eyes shut. I put off thought of all but my daily work till my task is done.
I thought I might have got up to see you, but I cannot now.
I see in the last “Nation” an article, which was evidently to have been continued, by Chauncey Wright, in which he points out clearly the essential difference between Darwinism, which is scientific, and Spencerism, which is “philosophical.” Save the mark!
Poor Wright,—your namesake—died suddenly of apoplexy, Sunday morning. He was a stanch Millite, and very acute and clear-headed.

... A minister out in Illinois has written me, taking me seriously to task for altering my opinion after the age of forty-five, and for abetting disorder, by supporting theories that disturb the harmony of opinion that ought to prevail among scientific men.
He is one of those people who think that if you shut your eyes hard, it will answer every purpose; indeed, from the ease with which he confutes Darwinism, I suppose he finds no call even to shut his eyes.

... Species, as I have said (in “Silliman’s Journal” articles) are not facts or things, but judgments, and, of course, fallible judgments; how fallible the working naturalist knows and feels more than any one else.
That the pages of a Flora or Fauna should give the idea of fixity and clear limitation which does not well or wholly represent the reality, is natural enough; is, indeed, inevitable. The object in these works is to set forth the differences, and put them in the strongest and clearest light, so that the forms may be readily discriminated. The nearer two forms are alike, the more pains the naturalist takes to set forth the differences, while the likeness “goes without saying,” and is therefore overlooked by the outsider, though it may have been almost an even chance that the describer merged the two in one.
