Promises to send coral specimens.

Action of facial muscles at onset of crying.
Langstaff has never seen the platysma act, and he believes it to be rudimentary in humans.

Asks for precise reference in Charles Bell to subject of CD’s question. Agrees to assist CD’s investigation. Asks about Bell’s observations on eyes engorged with blood. Has noticed that eyes of children with excessive photophobia tend to be pale when forced open.
Has circulated CD’s Queries about expression and gives some of his observations of the natives.
Gives Charles Bell’s explanation of the contraction of the orbicularis during screaming and seeks confirmation of his view because the action is "the key-stone of a whole class of expressions".

Finds important differences between English and German versions of Variation on graft-hybrids.

Movement in plants.
Dimorphism.
Would welcome FM’s opinion of Pangenesis.
Asks for [John?] Smith’s exact count of seeds of the crossed and self-fertilised Victoria water-lily. Similar question on Euryale seed and seedlings.

Otto Staudinger’s catalogue shows prices of female Lepidoptera to be higher than those of males.
Thanks for Variation.
CD must be happy about the tendency toward acceptance of his views, though it is regrettable that France is backward in this regard.
His own work goes slowly, but he still hopes his work on artificially produced monstrosities will help to answer the question of the origin of species.
Discusses apes and their relationships to each other. Writes particularly of the gibbon, its structure and well-developed legs giving it the ability to walk without using its hands.
Thanks CD for sending him copy of Variation.

Like ancestors of horses, young tapir is also striped.
