 detail, to be undertaken as soon as we left Italy. 

 He contracted a perfect fever for travelling. We

 myself. I liked no one better than genial artists. 

 Now Haeckel was seized with a passion for painting 

 landscapes day after day. He was especially 

 interested in the most fantastically shaped rocks. 

 On the other hand, he neglected his marine
