Thanks JS for essays. CD read the French abstracts [of "Hemisepius", K. Dan. Vidensk. Selsk. Skr. (Naturvidensk. Math. Afd.) 5th ser. 10 (1875): 463–82, and "Sepiadarium og Idiosepius", K. Dan. Vidensk. Selsk. Skr. (Naturvidensk. Math. Afd.) 6th ser. 1 (1880–5): 211–42]. Hectocotylisation has always astonished him.
Wishes JS believed in evolution.
