The production of that letter gives me neither surprise nor concern. I usually write and speak from the impression of the moment, and must expect occasionally, especially after an interval of nearly nine years, to find some inconsistencies in my opinions. In this case, however, the inconsistency is more apparent than real; but, be it great or small, you are welcome to any use you can make of it. The facts, as you well know, were these: In 1837 it seems that I was not satisfied with the management of the Reading Room, as the time in obtaining printed books was greater than it had formerly been. You succeeded to the Department, and introduced the Rules which have in practice proved inconvenient, but which were supposed to do much, within the first few weeks after your appointment, to remedy the evil. It seems also that you made other improvements, and that the changes elicited my praise. Experience has, however, proved that I was mistaken; and I have long since seen my mistake. So long as the apparent effect lasted, it appeared to justify the apparent cause. It was better to give ten minutes to the Catalogue, than to wait three, not to say six times as long (as I have often done of late) for a book. The additional trouble, however, remains, without the advantage which alone justified its imposition. It is really too much to oblige Readers to waste their time over the Catalogue, and to revert to worse than the old delays. So long as your plan worked well, I approved of it. For some years past it has worked ill, and I have condemned it. You wisely tried an experiment, but you unwisely continue the plan, though it has failed. I have no reluctance to avow a change in my opinions, whenever it has been produced by a change in the circumstances on which it was formed; but I have no respect for mulish obstinacy, or bigotted self sufficiency. You may be sure that if a convenient opportunity be afforded me for printing my letter to you of October, 1837, it shall, after collation with the original, be published. But I will not separate it from this correspondence. The English Public would learn with astonishment the manner in which, by a series of _unmarked_ quotations, a generous letter may be perverted to ungenerous purposes. I am, &c. P. S. Should you possess any letter from me commending the _plan_ of the _Catalogue_, I should be very happy to add it to our recent correspondence. N. H. N.
