"At first is was thought that the uncleft was a hard thing that could be split no further; hence the name. Now we know it is made up of lesser motes. There is a heavy *kernel* with a forward bernstonish lading, and around it one or more light motes with backward ladings. The least uncleft is that of ordinary waterstuff. Its kernel is a lone forwardladen mote called a *firstbit*. Outside it is a backwardladen mote called a *bernstonebit*. The firstbit has a heaviness about 1840-fold that of the bernstonebit. Early worldken folk thought bernstonebits swing around the kernel like the earth around the sun, but now we understand they are more like waves or clouds. In all other unclefts are found other motes as well, about as heavy as the firstbit but with no lading, known as *neitherbits*. We know a kind of waterstuff with one neitherbit in the kernel along with the firstbit; another kind has two neitherbits. Both kinds are seldom. "
