The small processes aresometimes well developed dendrites and occasionally the cells presenta typical multipolar or stellate form. Usually, however, the processesgive the impression of small and unimportant dendrites. I aminclined to think with Cajal (1896) that these dendrites are embry-onic and transitory, but would add that they have greater importanceand permanence in fishes than in higher forms. Often, even in. ^-^^
