These experiments as to her susceptibility to touch, or pressure, led to one slightly different, and which cannot as yet be said to have gone beyond its initial stages. I took a set of weights of 5, 10, 20, 30, 100, 200, 400, and 500 grammes, and also others of 1 and 2 kilo, and told Lola she must learn to know how heavy a thing could be. Then I placed the weights separately between her two shoulder-blades, naming them beforehand somewhat as follows--and having first written out a chart for her which set forth in a plain and easy form what I was going to say: 125 grammes = 1/4 lb. 250 grammes = 1/2 lb. 500 grammes = 1 lb. 1000 grammes = 1 kilogramme 100 lb. = 1 zentner I then explained this carefully and questioned her at once: "How many pounds are 375 grammes?" Answer: "3/4."[18] "How much are 1,000 grammes?" Answer: "2." I had intentionally refrained from putting questions as to figures that were on her chart which I had left lying before her; and after she had given her replies in accordance with the pressure she had felt between her shoulders, I tested her ability at guessing where greater differences of weight were in question. On two occasions she gave the right answers, namely "1 pound" and "2 pounds," I having put the question so as to obviate superfluous spelling. I then showed her the weights, placing them in a row before her, naming them again and saying: "Which is the heaviest?" She answered "4." As a matter of fact, the heaviest of these weights, the two-pound one, was actually standing fourth. I continued: "And now?" (I had for this question transposed the weights--unseen by Lola.) Answer: "1." Which was quite right! Then--"Where is the 100 grammes?" "3." "Where is 50 grammes?" "2," and "Where is one pound?" "5." Her answers, as will be seen, were perfect; she had learnt to understand what was expected of her in this test with great rapidity. [18] Fractions will be touched on in a later chapter on "Advanced Arithmetic." Indeed, more elaborate tests might have been undertaken but, unfortunately, I had little leisure at the time, and was without the assistance of any educated person who might have helped me in the work. As, however, the "spade-work" in this particular field of experiment seems now to have been accomplished, many additional and interesting details might result--given the right opportunity.
