Dear and honoured Sir,

I am very sorry that the wanted information I can give you about certain of my experiments will not be of much worth for you. On Primula I have not made any observations on the matter you asked me about, and my observations on the fertilisation of Corydalis cava had the result, that the flowers, when selffertilized, gave no seed at all, and after fertilization with flowers of the same Individual only a very few seeds.¹ The experiments on Hypecoum grandiflorum (Pringsh. Jahrb. VII p 465) had the following result:

number of seeds in each fruit after selffertilization

0, 0, 0, 0, 1, 2, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 2.   28

number of seeds in each fruit after fert with other flowers of the same individual:

0, 0, 0, 2   100²

Eschscholtzia californica (Pringsh. Jarb. VII p 467) number of seeds after selffertilization:

4, 17, 9, 0, 0, 0, 0, 4, 5, 11, 9, 0, 1, 0, 2, 12, 9, 7, 10, 27   66

n. of s. after fert. with other flowers of the same ind.

2, 7, 0, 22, 9, 26, 25, 2, 7, 10, 7, 3, 3, 1—100³

This is all I can tell you about the matter, you see that it is very little.

During winter I had made ready for printing a little work: Ùber den Verbreitungsmittel der Pflanzen”, but the strike of the printers at Leipzig made it impossible to get it printed, but I think now, that it will be published after some months.⁴ When I send you a copy, you will find therein something more about the cultivated Cereals and other similar things, that will be perhaps of some interest for you.⁵

Now excuse me, honoured Sir, for not answering your last letter before, and believe me | yours’ | respectfully | Hildebrand
