Discusses a unique plant fossil, possibly a Calamites in fruit and the logistics of JSH viewing it. States that rather than the fossil being sent to JSH, in its fragile condition it would be better for a drawing to be made under the supervision of his son, William Bowman. Offers to send JSH a description of the fossil via his son, along with analysis by Robert Brown. Recommends Brown’s analysis of the fossil for inclusion in Fossil Flora and states that it would make a good opening plate.
Also states that he has recently seen several specimens of an unusual Stigmaria in Leeds and has arranged for drawings and description to be sent to JSH for Fossil Flora. Gives his own description of the specimens as well. Offers to find coal fossils for JSH.
Unable to visit JSH as has been ordered to Hastings for health reasons related to ‘nerves’, brought on by stresses including his mother’s death and poor physical health.

Replies to CD’s questions on plant hybridisation and laws of inheritance. Rejects predominant transmission of characters by established forms. Males show predominance, but congeniality of parents’ constitution to climate and soil more important. No correlation between hybridisation and variability, cultivation, and geographical distribution. Rejects reversion.
Describes experiments in Hippeastrum in which pollen from another species proved more fertile than plant’s own pollen.
Did not intend to say that crossing is inimical to fertility.
