TO LUDWIG KUGELMANN IN HANOVER

[London,] 30 December 1889

Dear Kugelmann,

A Happy New Year to you.

Thank you for the prescription for my eyes, which, however, is not nearly concentrated enough for me. Last year and up till August I used cocaine and, as this grew less effective (on account of habituation), went on to ZnCl₂, which works very well. If I weather the present short days successfully—the last daylight we saw was on 28 December—since yesterday morning it has been perpetual night—I shall have put the worst behind me.

Kindest regards.

Your

F. E.
