The injection of the retrogradely transported fluorescing materials DAPI-Pr.

and EB in the extraocutar muscles of central gazing in the albino rat, shows rather circum- scribed cellular arrangements of their neuronal motor cells, Which is found to be the only difference with the columnar nuclear arrangements described in the literature for comparable nuclei in the monkey.

The finding is discussed with prosrrct to the differ- ent Of the eyes in these two species.

The motor cells of the superior oblique muscle are found to be the most in number.

The key Of the superior oblique muscle possibly required more nerve cells at itsdisposal, for it is thought to act before any of the individual muscles.

The muscles need a protraeted time to elapse before they follow suit in their actions upon the eye-ball.
