Summary:
Thanks for information about Pliocene mammal. Interested in relating process of formation to duration of the species. Oswald Heer’s view that species suddenly formed surely false.
Bad summer with much sickness. Going to Malvern [for water-cure] for a month.
Muddled over phyllotaxy and made out nothing.
