Yellow flowers occurring on a purple Cytisus grafted onto a yellow stock.
Yellow and purple flowers occur on plant grafted with Cytisus purpureus, but only on separate racemes. Only yellow blooms seed.
Sends CD some of the Cytisus, which has produced yellow flowers on a purple graft.
Describes the unusual appearance of a horse whose mother had previously borne a foal by a quagga. The effect of one mating on the subsequent pregnancy of another mating is explained by JJW using Pangenesis.
On behaviour of birds when frightened and when threatening.
Purple Cytisus grafted onto yellow stock produces some yellow flowers.
Mutations in rabbits.
Cites case of variegated leaf form of one plant apparently spreading to a neighbour.
On mutations in rabbits.
Cytisus case is not a double graft.
Aggressive behaviour of birds of prey.
On variegated leaves; a feature not inherited consistently.
Hostility of birds toward others with same colour;
nuptial plumage.
Spiza cyanea and Spiza ciris.
Hybrid Motacilla.
Case of female duck leaving mate to pair with male of another species.
Discusses case of Cytisus graft described by JJW.
Is very interested in JJW’s report on a purple laburnum grafted onto yellow stock which then produces yellow flowers. CD requests racemes to examine.
Regarding Cytisus graft with yellow flowers, CD thinks nurseryman has sold Cytisus adami to JJW’s brother in place of C. purpureus. This explains apparent "sport". [P.S. on envelope:] C. purpureus seeds freely. C. adami never does.
JJW is to think no more about mistake [regarding Cytisus graft].
E. Ray Lankester blackballed by Linnean Society. Another election planned. Would JJW use his influence in Lankester’s favour?
Declines invitation to accompany JJW to Crystal Palace.
Promises to propose JJW for membership in Zoological Society.
Sympathises with JJW’s enthusiasm about the Danais and hopes it may become naturalised in this country.
CD thinks JJW’s account [in 7137] is significant for a theory of generation and should go to some scientific society; suggests additional data is needed. Quotes cases of subsequent progeny apparently affected by a previous impregnation. Perhaps not prudent to allude to "despised" Pangenesis, which CD fully believes will have its day.
Asks about birds erecting feathers when enraged or frightened. Interested in examples of expression in birds and animals.
Tells of the sheldrake dancing on tidal sands to make worms come out.
On birds erecting feathers.
Comments on production of buds in Cytisus.
Discusses case of rabbit-breeding which affected subsequent progeny of female.
Cannot accept JJW’s invitation to a party. His health has been worse than usual for some months – can see no one nor can he go anywhere.
Is preparing a cheap edition of the Origin [6th] and will answer Mivart’s objections.
CD is pleased JJW likes C. Wright’s "Darwinism" [see 7940]. Huxley will publish a splendid review of it in Contemporary Review [Nov 1871].
