You ask where my favorite branch of science has gone and whether the history of development has suffered a bit under the whirlpool of social pleasures in which we find ourselves here in Nice. I don’t know what you think about the society in Nice. We did not choose it, as it mostly consists of English people, who, as you probably know, are among my national antipathies. The French play only a very subordinate role here, and the Germans are completely absent, as they are everywhere. I was determined to bring back a treatise on the development history of sea urchins or holothurians from Nice. The former are brought to market in large quantities as soon as the sea is calm enough to look down to some depth. You can usually find sea urchins in places where algae are present.
