has finished now all your woodcuts, so that you may expect them from the woodcutter in a very short time.²

The object in my writing today is a request from Prof. Kölliker³ of Würzburg who at present is in London for a fortnight, & anxious to pay you his respects. As his time is very much taken up by an examination of corals in the Museum, I advised him to ask you whether you would see him on Good-Friday, a day on which the Museum is closed.⁴ Thus, if you should be disengaged on that day, & if you & Mrs Darwin are inclined to receive visitors, Kölliker & myself would come by one of the morning-trains, walk from the station over to Down, & after a few hours stay return to London in the afternoon.

Kölliker stays with Sharpey⁵ at present, but has promised to shift his quarters to my house during Easter.

I hope you, Mrs Darwin & all your family are quite well, & remain | Yours very sincerely | A Günther
