68 LOLA 



not yet fetched the yard-stick, and she had, in fact, 

 not seen it for many weeks. So I pointed to the 

 outside edge of a small picture-frame that I at a 

 guess took to be about twenty-two centimetres in 

 length. At the same time I must own that I have 

 never exercised my judgment in this line to any very 

 great extent. " How long is this lower edge ? " I asked 

 her, " from here to here ? " (pointing) : her answer was, 

 " 25." I then tested it by the stick ; it was twenty- 

 six ! I pointed to a larger frame, putting the same 

 question, she answered "50." I measured, and 

 found it to be 75. Again I showed her a smaller 

 picture, and she rapped " 19." Then I showed her 

 a piece of chocolate " 7 " was her reply it was 

 seven and a half. Later on, when she was in the mood 

 she became able to guess within half a centimetre at 

 a distance of about thirty centimetres and at greater 

 distances up to one metre ; I estimated the difference 

 to vary from about one to ten centimetres. Of late 

 I have not given her much practice of this kind, for 

 from the beginning she has not cared much for it. But 

 I have made the experiment of seeing whether she can 

 distinguish colours in the same way we do. To make 

 this test I daubed some of the most important colours 

 on a sheet of paper, writing the name beneath each, 

 and the next day I daubed the same colours on another 

 piece of paper but in different sequence, and without 

 adding their names. The ready response to my 

 questions gave further proof as Lola's good memory 

 as well as of her perfect ability to differentiate. 



I next questioned her on more practical subjects. 

 I said : " What is the colour of the stove in this 

 room ? " at the same time looking out of the window 

 to make sure that she knew what a " stove " was. 

 " Green," was her answer and quite right too, for
