From Hermann Müller 4 October 1876
Lippstadt
Oct. 4. 1876.
My dear Sir
Many thanks for your kind letter of Sept 9. and for the cheque of £7·8 S. for my brother, which I received just now.1
I have many times looked at the male humble bees, but I have never succeeded in observing something like the regular traveling in certain pathways as observed by you.2 But it is to be remarked that the environs of Lippstadt are by no means abounding with humble-bees and therefore little favorable for these observations
In my last letter I have made a statement, regarding the habits of Bombus terrestris, which is to be corrected. As in the meantime I have seen from my notes, B. terrestris also in the Alps forcibly breaks open some flowers in order to gain their honey, for instance those of Silene inflata3
Your book on the Effects of Cross and Self-Fertilisation will be of the highest interest to me.4 It will stop, I hope, such publications as those of Pedicino and Comes of Naples and of Mr. Meehan of Philadelphia.5
As to Trifolium pratense I will remember during next summer what you mentioned about the bees searching for something between the flowers6
Yours | very sincerely | H Müller.

Summary
He has never observed the straight line flight routes in male humble-bees that CD reports.
His last letter was in error: alpine Bombus terrestris does break into some flowers.
