ed, that she was doing this obstinately and on purpose, so as to
put me off asking any more questions! And--if so--she certainly gained
her point. The lesson of this, is that one has to bear in mind that one
is not dealing with a _machine_, but with a living being--and with one
that is in many respects exceedingly "unreasonable" and particularly
"self-willed."

I had been devoting myself to this work for some months, and had lost
some of my earlier interest, but I started again three days ago so as
to have another test to set down here. Lola proved to be up to the mark
again, seemed interested, and I did my best to encourage her by saying:
"You _will_ be pleased when you know _this_!" ... "This _is_ nice!" ...
"See how much more a dog knows than many a man!" and so on. And as a
result she announced on 5 January, 1917.

For 6 January = b (a little rain).
For 7 January = r (rain).
For 8 January = r (rain).

On 6 January, there was half a degree of cold, and snow fell later in
the day. This answer was near enough, for she had not been taught
"snow," yet the equivalent might doubtless be found in a little "rain,"
i.e. wet. On 7 January, we had a heavy fall of snow, and another on 8
January. So that this test succeeded, if we discount the snow instead
of rain, a change occasioned by the colder atmosphere.

ADVANCED ARITHMETIC

As the reader will now know, Lola was already acquainted with the
simpler modes of arithmetic--such as addition, subtraction,
multiplication and division; and we continued practising these forms
for some time, even though my mind was already busy planning other and
more ambitious tests. Arithmetic had of late only been taken as a
corollary to her other studies, but the time seemed to have come when
further advance in this too, might be deemed desirable. Her ability to
"reckon" had already proved itself of practical use in facilitating her
other accomplishments, and I determined now to try and put it to a
still more objective test, first of all in such simple forms as: "How
many people are there here?" Answer: "7." "How many of them are women?"
Answer: "6." "How many dogs are there in this room?" Answer: "1." "And
who is that?" "Ich" (I). A little later I said: "Listen to me, Lola!
There are thirty cows in the stalls; ten of those cows go to graze, and
two cows have been killed, how many cows remain in the stalls?" Answer:
"18." Then I said: "Six oxen are in the stalls--how man
