and I concluded with a few more verbal elucidations, and then fetched an actual thermometer on which I made her read me the temperature of the room. The next day I repeated this lesson and she read the thermometer again. After this I tested her as to whether she could give the temperature by the "feel," as it were, or whether the impression of the temperature was associated more immediately with a sense of comfort. She has so far always given the right temperature when asked, though I should add that I have only put the question to her about twenty times--and then when she has been in good health, so that I feel that the matter has not yet been sufficiently put to the proof, and I cannot, therefore, make any very definite statements with regard to this particular faculty. But I must add, that to two questions put to her on different days, she answered that she "liked her food best at 6 deg. of warmth!" Now this chimes with the advice given in many a book on the care of dogs; "do not give them their food too hot"--and Lola's remark reminded me of this, though I might consider that "degree of heat" practically _cool_ ... yet it appeared to be what she desired. Nevertheless, this preference turned out shortly to have been erroneous and, as the result of a practical trial, Lola changed her mind and voted for anything "between 12 deg.--16 deg.!" Here is one more test I put with regard to her susceptibility to touch: I got someone else to trace figures with their fingers on the dog's back, placing myself so that I could not see what was being described; then I put the questions, and each time her replies tallied almost invariably. One put to her in this manner was: "2 + 3?"; and "5" was given at once. While "7 + 4?" elicited a prompt "11." Then a number was described and I said: "Twice this number makes?"; to which she replied "8," four having been traced on her back. We only tried this new test for a few days so that I can give no more exact details about it--excepting this, that on that particular day, she would only understand the figures _if inscribed in this manner on her back_! It evidently amused her immensely, and we could see that she seemed to "transfer her attention," as it were, elsewhere. But though this test had been so successful with numerals, it failed entirely with letters. This was incidentally an attempt on quite a small scale at carrying out the tests which had been successfully so put to the blind horse Bertho, by Karl Krall.
