Experiments are not going well, but the quantity of blood transfused was small.
Explains that law of inertia, and most of modern mechanics, is all wrong. Explains his concept of "elasticity" of bodies. Applies it to physiology.
The illness and death of his daughter have delayed his answers to CD’s queries. He has, however, worked on the circulation of the eye and has almost finished a paper on it, which he will send to CD. In general, the views of Charles Bell are confirmed.
As for CD’s second query, he doubts that the relationship exists, but will answer fully in next letter.

Asks CD to look at the "special phylogonies" on pp. 138 and 152 of his book [Forms of animal life (1870)]. His comments are based on reading Haeckel, who is highly speculative and quite wrong.
Italian translation [of Variation] is delayed, but printing should begin soon.
Will send CD one of his writings in which he defends the natural descent of man [Origin dell’uomo, 2d ed. (1870)].
CD’s theory is making great progress in Italy and daily gains supporters.
Is not prepared to express an opinion on man’s origin. On pure anatomical grounds he would form a family of the higher division of the primates, but if man’s intellectual, moral, and religious nature is considered, then "he differs more from an Anthropoid Ape than such an Ape differs from a lump of granite".
