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 many legs have six oxen?" Answer: "24." and so we continued, the right reply being generally given after this exercise had been repeated a few times. In May, 1916, Lola learnt the big multiplication-table, doing so easily and quickly. She was at first slightly inaccurate in the higher numbers, for rapping out the "hundreds" with the right paw and the "tens" with the left--and then again the "ones" with the right gave her some trouble in the beginning. Yet such questions as: 3 + 14, 2 + 17, 4 + 20, were given without hesitation, since these did not come within the region of the hundreds. But in time she got used to the hundreds too--and even to thousands, and to these latter she applied her left paw, rapping the date 1916 thus: left paw 1; right paw 9; left paw 1; right paw 6.
