Young Belgian students [L. A. Errera and Gustave Gevaert] ask CD to read their paper, which summarises Cross and self-fertilisation. They criticise CD’s views on the comparative effects of crossing flowers on the same stem and fertilisation of a flower by its own pollen ["Sur la structure et les modes de fécondation des fleurs", Bull. Soc. Bot. Belg. 17 (1878): 38–181, 182–248].

Sending MS.

Used Anton Kerner’s nomenclature for designating crosses.

Thanks CD for Forms of flowers.
