THOMAS CARLYLE. 375 



early hour, I found him vigorously marching along the 

 fringe of the Mediterranean. In the afternoon we had 

 a longe drive on the Corniche Road. The zenithal 

 firmament, as we returned, was a deep blue, the western 

 sky a fiery crimson. Xewton's suggestion it could 

 hardly be called a theory as to the cause of the 

 heavenly azure was mentioned. Carlyle had learned a 

 good deal of natural philosophy from Leslie, of whom 

 he preserved a grateful remembrance. From Leslie he 

 had learnt Xewton's view of the colour of the sky, and 

 he now stood up for it. Leslie, he contended, was a 

 high and trustworthy authority. " An excellent man," 

 I admitted, " in his own line, but not an authority on

 press his point, while I continued to resist. He became 

 silent, and remained so for some time. A "dependanee" 

 of the Villa Madonna had been placed at his sole dis-

 returned from our drive. I helped him to put on his 

 dressing-gown. Throwing himself into a chair, and

 there and tell me all about it." I sat down, and he 

 listened with perfect patience to a lengthy dissertation 

 on the undulatory theory, the laws of interference, and 

 the colours of thin plates. As in all similar cases, his 

 questions showed wonderful penetration. The power 

 which made his pictures so vivid and so true enabled 

 him to seize physical imagery with ease and accuracy. 

 Discussions ending in this way were not unfrequent 

 between us, and, in matters of science, I was always able, 

 in the long run, to make prejudice yield to reason. 

 On the day of my departure we all drove to Monaco 

 our warm-hearted hostess, Carlyle, and a young lady 

 who was then a lovely child, and who is now a charm-
