I sail from Edinburgh on the 13th instant for Göthenburg, Sweden. I then go to Holma on the west coast of Sweden to visit professor Otto Petterssen of Stockholm and also Prof. Theel’s station.
I'll be in Stockholm about the 18th or 20th of August and will then || take a steamer to Helsingfors, probably on Saturday the 21st instant If you send a note to the care of
Professor Otto Petterssen
Hofschola
Stockholm
this will find me. I think you said you would be in || Stockholm before going on to St. Petersburg.
My best wishes for your good health and that of Mrs Haeckel and all your family.
We are just settling down in our new house, and are busy with painters, plumbers &c. &c.
