Summary

JDH has probably influenced Bates by pointing out applicability of CD’s views to his cases.

Summary

Lighthearted thoughts on "the development of an Aristocracy" after a visit to Walcot Hall, Shropshire.

On CD’s point about the effect of changed conditions on the reproductive organs, JDH does not see why this is not "itself a variation, not necessarily induced by domestication, but accompanying some variety artificially selected".

Summary

Identifies Calanthe masuca.

Asa Gray would not quarrel with them – "snubbing from us may have done him more good than our sympathy".

If CD means the old Vaucher, he was considered a very accurate, acute, able observer.

Summary

Variations are centrifugal because the chances are a million to one that identity of form once lost will return.

In the human race, we find no reversion "that would lead us to confound a man with his ancestors".

Summary

Discusses Leschenaultia, finds no stigmatic surface in the indusium.

Gives information on where to obtain paper for drying plants and where to obtain a microscope.

Summary

Has dissected Leschenaultia biloba flowers. Finds no stigmatic surface in the indusium. Describes what is the apparent stigma but has found no pollen-tubes to confirm it as the real one.

Summary

Household problems – stolen silver, maids. His house for some months has had reputation for being not a little disreputable.
