A believer in evolution seeks to convince CD that a spiritual creative force, rather than natural selection, explains its operation.

Summary

Are plants that arise from vegetative propagation individuals or merely parts of the original parent plant?

Summary

In response to CD’s query, answers that he has frequently heard discussions at the Horticultural Society of a saccharine secretion from leaves of the lime and has no doubt it really does occur. [See Cross and self-fertilisation, p. 402.]

Summary

Has sent his paper on Echinoidea [see 10373] as a token of his veneration. He tried to address the confusion in knowledge about the different parts of the exoskeleton of the Echinodermata by tracing certain relations of homology not previously noticed. Much more work is required.

Asks whether CD agrees that it is "no longer a fact" that the bladders of Utricularia vulgaris enable the plant to become lighter for fecundation and heavier when that act is accomplished. Plans to undertake further observations, under very high-powered microscopes, of mechanism of digestion.

Summary

Reports on the tendency of the normally fruitless Convolvulus arvensis, to form fruit when roots are cut and plant is in danger of dying.

Summary

He is surveying the literature on the struggle for existence among pasture plants. Asks CD for the "many cases on record" of changed relations among plants under slightly changed conditions alluded to in the Origin. [See M. T. Masters, J. B. Lawes and J. M. Gilbert "Agricultural, botanical, and chemical results of experiments on the mixed herbage of permanent meadow, conducted for more than twenty years in succession on the same land (pt 2, The botanical results)", Philos.
