There is nothing so attractive in this controversy as to induce me to bring others into it; and if you do not choose to believe my assertion, I cannot help it. I have not presumed to doubt anything you have said, nor to impute improper motives to your conduct. But courtesy is a matter of feeling, and I have no right to expect you to imitate me. I must again say, that the matters under discussion can only be settled by a higher authority than yours. _You_ have brought the subject before the Trustees,--_I_ have, as I usually do on subjects which concern the Public, laid the facts before the Public. You can vindicate your proceedings either to the Trustees or to the Public. I avow and maintain all I have, and all I may yet say; but I decidedly decline to continue this correspondence, because I am sure it can lead to no desirable result, and for the other reasons which I have assigned. I consider the subject one of a _Public Nature_, and regret to perceive that you are angry; for, until your last letter, I had determined to avoid making any _personal remark_ likely to displease you. Believe me, &c. I can have no sort of objection to your laying this and my last letter, together with the communication which you will receive from me on Monday next, before the Trustees, if you see fit. No. XI. _Mr. Panizzi to Sir N. H. Nicolas._ May 27th, 1846. SIR, I am surprised to find that the expressions which displease you most in my letter of the 26th instant, are those which I transcribed _verbatim_ from one which you volunteered to write to me in 1837,[C] and of which I enclose a copy. You _then_ warmly approved of those very arrangements which you _now_ so violently condemn. I call upon you to publish the enclosed along with the observations which you are to send me on Monday next, in order that all unprejudiced and sincere persons may judge what reliance is to be placed on the opinions and assertions of a man endowed with so flexible a judgment, and so treacherous a memory. I am, &c. No. XII. _Sir N. H. Nicolas to Mr. Panizzi._ Torrington Square, 26 May, 1846. SIR, Your communication of this day induces me, most reluctantly, to add one more letter to our correspondence. It is proper that I should advert to my letter of the 20th of October, 1837, of which you have made so candid and gentlemanly, and, if I condescended to imitate your style, I might say, so "_characteristic_" a use.
