This last process of "continually producing the lines," may require centuries or more; but such a period, though long in the life of an individual, is as nothing in the life of the University.

As Photography is now very much employed in recording human expression, and might possibly be adapted to Algebraical Expressions, a small photographic room would be desirable, both for general use and for representing the various phenomena of Gravity, Disturbance of Equilibrium, Resolution, etc., which affect the features during severe mathematical operations.

May I trust that you will give your immediate attention to this most important subject?

It was at the end of December, 1878, that a letter, written in a singularly legible and rather boyish-looking hand, came to me from Christ Church, Oxford, signed "C.L. Dodgson." The writer said that he had come across some fairy designs of mine, and he should like to see some more of my work. By the same post came a letter from my London publisher (who had supplied my address) telling me that the "Rev. C.L. Dodgson" was "Lewis Carroll."

"Alice in Wonderland" had long been one of my pet books, and, as one regards a favourite author as almost a personal friend, I felt less restraint than one usually feels in writing to a stranger, though I carefully concealed my knowledge of his identity, as he had not chosen to reveal it.

This was the beginning of a frequent and delightful correspondence, and, as I confessed to a great love for fairy lore of every description, he asked me if I would accept a child's fairytale book he had written, called "Alice in Wonderland." I replied that I knew it nearly all off by heart, but that I should greatly prize a copy given to me by himself. By return came "Alice," and "Through the Looking-glass," bound most luxuriously in white calf and gold. And this is the grateful and kindly note that came with them: "I am now sending you 'Alice,' and the 'Looking-glass' as well. There is an incompleteness about giving only one, and besides, the one you bought was probably in red, and would not match these. If you are at all in doubt as to what to do with the (now) superfluous copy, let me suggest your giving it to some poor sick child. I have been distributing copies to all the hospitals and convalescent homes I can hear of, where there are sick children capable of reading them, and though, of course, one takes some pleasure in the popularity of the books elsewhere, it is not nearly so pleasant a thought to me as that they may be a comfort and relief to children in hours of pain and weariness. Still, no recipient can be more appropriate than one who seems to have been in fairyland herself, and to have seen, like the 'weary mariners' of old—

"Between the green brink and the running foam
White limbs unrobèd to a crystal air,
Sweet faces, rounded arms, and bosoms prest
To little harps of gold."

"Do you ever come to London?" he asked in another letter; "if so, will you allow me to call upon you?"
