sunburned and looking very much better than when I last saw him. 

 Of course, I was delighted to have a glimpse of him again. He stayed 

 until this morning and, as you may imagine, I did not do any vast 

 amount of work, while he was here. On Tuesday, we went about to- 

 gether and visited a number of his friends here and, in the evening, at 

 Prof. Kiihne's invitation, we went to a 'Kneipe' in the Cafe Leers. . . . 

 Yesterday, also, was chiefly spent with Balfour. In the morning, he came 

 to the laboratory and we worked over some points of common interest 

 together. ... In the afternoon we took quite a stroll, up to the Castle 

 and from there, to the Molkenkur. . . . The fear of a shower sent us 

 scrambling down the hills and, reaching town in safety, we went to 

 call upon the Pacha. . . . We stayed only a few minutes, of course, 

 and then went off for some more calls. Every one received him with 

 open arms. He is, indeed a splendid fellow and, when I am with him, 

 I feel very insignificant. 



"In the evening, we were both invited to tea at Professor Kiihne's. 

 I enjoyed it greatly. The famous physiologist is an immense man, and 

 weighs 256 pounds! but is as jolly and full of fun as he can be; his 

 wife is very pretty and very pleasant (a German friend of mine called 

 her 'eine sehr Hebe Frau'). Balfour is always briUiant and so we had 

 a jolly party. The only drawback was that we stayed so long. I couldn't 

 make the move and Balfour wouldn't, so we stayed on until twelve 

 o'clock. I am sleepy enough today, for having been up so late the last 

 two nights. Balfour went off to Jena this morning at 9.05, I, of course, 

 going to the station to see him off. I hope to see him again in England, 

 on my way home." 



This was the last opportunity for real companionship with Balfour 

 that I ever had, for, though I saw him again at York a few weeks later, 

 there was little opportunity for more than casual greetings, as he was 

 very busy. In Heidelberg, however, I had him largely to myself and, 

 as he was my hero in those days, I enjoyed his society more than I can 

 express. Our association was on a basis of entire equality, for he never 

 put on the least "side," never seemed to think that he was "anybody 

 in particular." In our technical discussions, he always treated my opinion 

 with respect, however much he might disagree with it. On the other 

 hand, I was always careful to maintain a respectful attitude toward him 

 and always called him "Mr. Balfour." I was often tempted by his good 

 fellowship to drop the "Mr." but I thought: "If he would like me to 

 drop it, he would tell me so," but he never did.
