Suggests change in sentence of JDH’s "Insular floras" to make meaning clear.

Naudin’s letter about hybrids.

Pangenesis.

Thanks for Agassiz’s Lectures. Lyell does not believe a word about glacial action of any kind in lowlands of Brazil. Agassiz’s view of glacial movement has been given up by physicists.

Summary

Returns Charles Naudin’s letter with its case in support of CD’s view of impregnation.

Friedrich Hildebrand’s new book on fertilisation of plants [Die Geschlechten-Vertheilung bei den Pflanzen (1867)].

CD correcting proofs of Variation.

FM likes Ernst Haeckel’s book [Generelle Morphologie (1866)].

Rejoices over baby’s improvement.

Horace Darwin has intermittent fever.

Susan Darwin’s death [Oct 1866] has severed last ties of family with Shrewsbury.
