16 August, 1916: "Lola, rap something!" "mal one lif unartig sein." "What is the meaning of 'lif'? do you mean 'when you ran'?" (lief = ran, the past tense of laufen = to run). "no." "Did you learn that word from me?" "yes." "Then explain yourself." "ich rante in wald zu re" ( = I ran in the wood after deer). Apparently she was in no mood for explanations, and it was only after wrestling with her that I could get any sequence of words at all. At other times when urged to get on with the subject she will in her contrariness rap as follows: "o zu ich" or "e wo zu" or "zum zu wozu" or "we" and so on--letters with which it is rarely possible to put together even such small words as _wo_ ( = where) or _zu_ ( = to, or for) and the longer one persists on such occasions, the more senseless her remarks become; it is the rarest thing for her to suddenly pull herself together so as to give a proper answer. And here again I can find no excuse for her behaviour; though it may be that she dislikes my persistence, and therefore has recourse to any nonsense by way of a quick reply! So as to get her in some manner to recognize the errors of her ways I have again and again persevered with the utmost patience, so as to arrive at some consistent answer--yet all I have succeeded in arousing, has been increased reluctance on the dog's part. MATTERS WHICH--SO FAR--ARE UNACCOUNTED FOR, OR UNEXPLAINED As will, indeed, be evident, there is still much that remains unexplained; much that it will be the task of the future to throw light upon. Tests which have been but uncertain in their results; accidental discoveries, the importance of which only becomes evident, after the results have been tested in connexion with a number of animals. Among these may be placed the more recent experiments dealing with the sense of scent, undertaken by Professor Jaeger, and in this category should be placed also what I think to be a rather interesting test connected with Lola: I was at the time staying with my family at Hohenheim, and I asked the dog how many pups her mother had had--including herself: she answered "12." I inquired of Professor Kraemer if this was so, and he said that at the time at which he had seen them there had only been eleven. I then made the same inquiry in Mannheim, and found that there had been twelve, but that one had died immediately after birth. It was the only instance of which Lola knew about a dog having pups, so one day I asked her in fun (19 June, 1916). "How many children will you have?" (Thinking that the answer would be 12). At first she replied with "yes!" "Do you know how many? why that's impossible!" But she rapped "9." "How many boys?" I asked. "3." "And how many girls?" "6." I thought that this statement was due merely to her desire to make some answer, so I put the same question the next day--but the reply was again, "9." So I told my friend about this and we awaited the
