The earthquake of Concepción.
His geological observations (since November). Can now prove both sides of the Andes have recently risen to considerable heights.
Zoological collection.
Plans to cross the Cordilleras.
Has just returned from crossing the Cordilleras. Geological observations of formations representing great epochs of violence which broke up the earth’s crust. Shells at over 12000 feet. Silicified trees in sandstone formations at great heights. Red snow and viviparous lizards. Botanical specimens.
His trip across the Andes and back was his most successful excursion: can clearly demonstate that the western part of the double line of mountains is much older, with fossil shells at 12000ft; the eastern line may be as modern as the Patagonian plains. If proved, this is an important fact in the theory of the formation of the world. Has found petrified trees.

Living quietly on the ship and eating good food has been good for him. He longs for home. Peru is in a miserable state.
Some of CD’s letters were read at Geological Society in London. Professor Sedgwick says of CD, "doing admirably … collection above all praise … will have a great name among the Naturalists of Europe".
