56 ALEXANDEK VON HUMBOLDT. 



dated from Eue de la Vieille Estrapade, No. 11 ; in 1809 from 

 Rue St. Dominique d'Enfer, No. 20 ; in 1812 from Rue d'Enfer, 

 No. 67 ; afterwards from the Hotel d'Anjou, Rue des Francs- 

 Bourgeois; and in 1813 from Quai Malaquais, No. 3. When 

 lie came to reside at Berlin it was some time before he could 

 accustom himself to the change of hours, and upon his return 

 from a visit to Paris in 1835 he thus writes to Schumacher: 



1 Berlin : August 2, 183d 



<I have been much refreshed and my health has greatly 

 benefited by my visit to the modern Babylon, where I have 

 again experienced how conducive to work is the custom that 

 prevails there of dining late now between seven and half-past 

 seven at least for those who, like myself, find even a breakfast 

 of half a cup of black coffee concentrated sunbeam, as old 

 Delisle used to call it almost more than they want during the 

 day. I again adopted the plan of having two residences, sleep- 

 ing in one and running off to work in the other at eight o'clock 

 in the morning, before the enemy was up to seize me. My 

 harbour of refuge was an inaccessible writing-room belonging 

 to my friend Arago, in the entresol of the Institute. Accus- 

 tomed at Berlin to receive visits only from such men of science 

 as came on official business from the king or the ministers, 

 and who, fearing to interrupt me, cut short every scientific 

 conversation, I greatly enjoyed the stimulating society and 

 facilities of work afforded me at Paris. I have at length suc- 

 ceeded in bringing out my "Examen critique," a folio of 

 seventy sheets. I spent several hours daily with Arago at the 

 Observatory, and passed my evenings till two in society, be- 

 sides being occupied in the absence of Baron Werther with 

 some political business for the king, which you may possibly 

 lave surmised from the report in the newspapers of my frequent 

 visits to the Tuileries.' 



A graphic description of Humboldt's daily routine is fur- 

 nished by Karl Vogt, 1 which, although referring to a later 

 epoch (1845), is almost equally applicable to the period now 

 before us. ' The early morning hours from eight till eleven 

 are his garret hours, spent in poking about the nooks and
