IN VAUIOUS P.iRTS OF THE GLOBE. 199 



15th I proceeded to Cocabainbilla and visited the forests, where 

 grows the Cinchona scrobiculata, one of the species observed by 

 MM. Humboldt and Bonpland in the province of Jaen, on 

 the frontiers of the Republic of the Equator. 



At Santa Ana my travels in America may be said to have come 

 to an end, and I there bid farewell to the vegetation of the 

 Tropics, for after my return to Cuzco I saw in America few trees 

 besides Willows, the Schinus and Pear trees of Arequipa, or 

 the Dates and Olives of Pisco and of Lima. 



On the 29th of August I started for Arequipa, where I 

 arrived on the 7th of December, after crossing a country very 

 like that which I passed on my way from Puno. 



Finally, on the 31st of October, I crossed the 30 leagues of 

 sand which separate Arequipa from Ysla, and on the 10th of 

 November I embarked for Lima, and thence, on the 8th of 

 December, for Europe. I returned to France on the 29th of 

 March, 1848, after an absence of five years.
