ical_ puzzles of late. I got into a regular tangle
about the "import of propositions," as the ordinary logical
books declare that "all _x_ is _z_" doesn't even
_hint_ that any _x_'s exist, but merely that the
qualities are so inseparable that, if ever _x_ occurs,
_z_ must occur also. As to "some _x_ is _z_"
they are discreetly silent; and the living authorities I
have appealed to, including our Professor of Logic, take
opposite sides! Some say it means that the qualities are so
connected that, if any _x_'s _did_ exist, some
_must_ be _z_--others that it only means
compatibility, _i.e.,_ that some _might_ be
_z_, and they would go on asserting, with perfect
belief in their truthfulness, "some boots are made of
brass," even if they had all the boots in the world before
them, and knew that _none_ were so made, merely because
there is no inherent impossibility in making boots of brass!
Isn't it bewildering? I shall have to mention all this in my
great work on Logic--but _I_ shall take the line "any
writer may mean exactly what he pleases by a phrase so long
as he explains it beforehand." But I shall not venture to
assert "some boots are made of brass" till I have found a
pair! The Professor of Logic came over one day to talk about
it, and we had a long and exciting argument, the result of
which was "_x -x_"--a magnitude which you will be able
to evaluate for yourself.

As an example of the good advice Mr. Dodgson used to give his young
friends, the following letter to Miss Isabel Standen will serve
excellently:--

Eastbourne, _Aug_. 4, 1885.

I can quite understand, and much sympathise with, what you
say of your feeling lonely, and not what you can honestly
call "happy." Now I am going to give you a bit of philosophy
about that--my own experience is, that _every_ new form
of life we try is, just at first, irksome rather than
pleasant. My first day or two at the sea is a little
depressing; I miss the Christ Church interests, and haven't
taken up the threads of interest here; and, just in the same
way, my first day or two, when I get back to Christ Church,
I miss the seaside pleasures, and feel with unusual
clearness the bothers of business-routine. In all such
cases, the true philosophy, I believe, is "_wait_ a
bit." Our mental nerves seem to
