250 LONDON AND CAMBRIDGE. ,-ETAT. 28. [1837. 



" N. B. Mr. Darwin may measure at any part of the room 

 he pleases." 



Besides arranging the geological and mineralogical speci- 

 mens, he had his ' Journal of Researches ' to work at, which 

 occupied his evenings at Cambridge. He also read a short 

 paper at the Zoological Society,* and another at the Geologi- 

 cal Society,! on the recent elevation of the coast of Chili. 



Early in the spring of 1837 (March 6th) he left Cambridge 

 for London, and a week later he was settled in lodgings at 

 36 Great Marlborough Street ; and except for a " short visit 

 to Shrewsbury " in June, he worked on till September, being 

 almost entirely employed on his 'Journal.' He found time, 

 however, for two papers at the Geological Society.]; 



He writes of his work to Fox (March, 1837): — 



4< In your last letter you urge me to get ready the book. I 

 am now hard at work and give up everything else for it. Our 

 plan is as follows : Captain Fitz-Roy writes two volumes out 

 of the materials collected during the last voyage under Capt. 

 King to Tierra del Fuego, and during our circumnavigation. 

 I am to have the third volume, in which I intend giving a 

 kind of journal of a naturalist, not following, however, always 

 the order of time, but rather the order of position. The 

 habits of animals will occupy a large portion, sketches of the 

 geology, the appearance of the country, and personal details 

 will make the hodge-podge complete. Afterwards I shall 

 write an account of the geology in detail, and draw up some 

 zoological papers. So that I have plenty of work for the 

 next year or two, and till that is finished I will have no holi- 

 days. "
