Glacial action in the Andes.

Origin of Chilean sheep.

Varieties of S. American horses.

Summary

Natural selection does not explain why animals of different groups in the same place often resemble each other.

Summary

Discusses Origin, suggesting confirmation might come from studying reproduction in microscopic organisms.

Gives anecdotal observations of blind rats and white cats.

Summary

JDH’s page-by-page criticisms on Origin, first edition, as requested by CD for preparation of the third edition.

Summary

Would be glad to have Chauncey Wright’s [Origin] review for the Natural History Review.

Summary

Response to [3020]. CD has been misled by errors made in the Times notice [5 Dec 1860, p. 5]. GCW does not doubt that Foraminiferous matter as well as other deep sea deposits vary greatly in thickness, but positive results are difficult to establish. Some areas of the sea bed are bare but their extent has not been established. He now thinks that he was too hasty in the conclusion that deep currents produce abrasion and rounding of gravel.

Summary

Charlotte [Wedgwood Langton?] reports from Mr Wallis on time of day that sundew opens.

Summary

CD’s article worth publishing in Gardeners’ Chronicle. JDH interprets CD’s observation in terms of selection. Has observed similar phenomenon in Cruciferae, where it can be taxonomically important.

Summary

Gives observations on the habits of the "agricultural ant" of Texas.
