Alexander Bain an Ernst Haeckel, Jena 
not having the pleasure of meeting you this afternoon, I shall feel greatly obliged if you will inform me at what how tomorrow, I might have that pleasure. ||
I am aware that tomorrow is the opening day of the summer semestre, an that you are likely to be more than usually occupied with your preparations. But I trust it may be possible for you to fix || an hour when I might wait upon you: as I shall have to leave for Weimar on Tuesday.
With highest respect,
