C. Carter Blake, "a jackal of Owen’s", is the reviewer in Edinburgh Review and Anthropological Review [see 4223]. Has sent back his diploma of Hon. Fellowship to Anthropological Society.
Has extracted CD’s Linum paper [Am. J. Sci. 2d ser. 36 (1863): 279–84].
Elaborate co-adaptations of orchids and insects demonstrate against "chance blows", whether few, as Oswald Heer would have, or many and slight as CD proposes.
Sends seeds of female Lychnis diurna; has found none in hermaphrodites.
On variation, hybridity, and inheritance of parasites in this plant.
Discusses leaf form and phyllotaxy; clarifies a part of his paper ["On a protomorphic phyllotype", Atlantis (1863)].
On CD’s request to observe bee Ophrys: PHG’s son collected 16 plants – of the 32 flowers, two had lost both pollinia, two had lost one each. He himself found two plants with pollinia adhering to the stigma.
He and L. C. Treviranus have repeated many of CD’s orchid observations with the same results. Sends his paper ["Fruchtbildung der Orchideen", Bot. Ztg. 21 (1863): 329–33, 337–45].

Discusses heterostyly in Hottonia.
Criticises L. C. Treviranus’ statements on Primula longiflora’s having short-styled form.

Difficulty in getting his orchid paper published in Edinburgh New Philosophical Journal.
Describes the similarity in plumage changes between Japanese and Chinese birds on the one hand and British and continental birds on the other. Suggests the changes are due to the warm gulf streams around both islands.

Doubts CD’s view in Orchids [pp. 236–46] that Catasetum tridentatum is exclusively male and has as its female form the genus Monachanthus. EB has grown many of this type in Trinidad; has never seen that female form.
