115. (11th April.) I was interrupted yesterday, and I am glad of it, for here happens just an instance of the way in which the unjust distribution of the burden of charity is reflected on general interests; I cannot help what taint of ungracefulness you or other readers of these letters may feel that I incur, in speaking, in this instance, of myself. If I could speak with the same accurate knowledge of any one else, most gladly I would; but I also think it right that, whether people accuse me of boasting or not, they should know that I practise what I preach. I had not intended to say what I now shall, but the coming of this letter last night just turns the balance of the decision with me. I enclose it with the other; you see it is one from my bookseller, Mr. Quaritch, offering me Fischer's work on the _Flora of Java_, and Latour's on _Indian Orchidaceae_, bound together, for twenty guineas. Now, I am writing a book on botany just now, for young people, chiefly on wild flowers, and I want these two books very much; but I simply cannot afford to buy them, because I sent my last spare twenty guineas to Mr. Shields yesterday for this widow. And though you may think it not the affair of the public that I have not this book on Indian flowers, it is their affair finally, that what I write for them should be founded on as broad knowledge as possible; whatever value my own book may or may not have, it will just be in a given degree worth _less_ to them, because of my want of this knowledge.
