Stewart Dickson lectured about his stereoliths.

The models, made from a translucent polyester resin, were about 20cm across, with a shell 2cm thick.

Bernard Morin enjoyed the models during the Maubeuge conference, and got to take them home afterwards.

Dickson spent some time talking with Morin about these models; Morin demonstrated with puckered lips the way the gastrula neck starts to twist as it closes.

Before the Maubeuge conference, Dickson and John Sullivan visited Morin at his apartment in Paris.
