Observations of fear in animals marked by dilation of pupils.
Is staying at a friend’s [T. H. Farrer’s] house for rest until after 6 July, so cannot see CVR at Down.
Hopes he thanked CVR for the last Report [one of CVR’s Annual reports on the noxious, beneficial and other insects of the State of Missouri (1868–76)].
