1. Two sprigs of something looking like seaweed have survived; they are preserved with this letter (inv. no. b76 V/1962). In fact they are not seaweed. The larger is a moss animal, a bryozoan: Flustra foliacea (hornwrack); the smaller is a hydroid: Hydrallmania falcata, to which three minuscule mussels adhere. Ill. 1918 . Both were formerly considered zoophytes. See Gerhard C. Cadée, ‘De doos van Pandora. De zee(w)(d)ieren van Vincent van Gogh’, Gewina.
