From Friedrich Hildebrand   26 July 1875

Dear and honoured Sir

I am very sorry that I cannot give you the results of any new experiments made one the varieties of maize.¹ Since my paper in the Bot. Zeit of 1868² I have only been looking out for some constant varieties of maize, but I always failed in getting a constant red variety. This year it would be to late for new experiments, but I shall be very glad if you could procure me next year the seeds of any constant varieties to make the experiments you suggested to me in your kind letter.

I have read with great admiration the first part of your book on “Insectivorous plants” and I am glad that your investigations have made this matter quite doubtless.

With all respect I remain | dear Sir | yours sincerely | Hildebrand
