A comparative study of distribution of alkaline and acid phosphatases, 5-nucleotidase and ATPase in various regions of peripheral and central nervous system of a large variety of animals i. e. in the nuclei of the neurons of olfactory lobes of rat, bat, guinea-pig, mouse, cat, rabbit, frog, chicken, turtle and uromastix, trigeminal ganglia of cat, dog and turtle, spinal ganglia of turtle, vagus ganglia of frog, primordial hippocampal region of turtle and frog, entopeduncular nucleus of frog and cerebellum of cat have presented specific patterns of distribution in the nucleolar and nuclear sites. In some cases the nuclei have revealed absence of activity for certain enzymes. The data obtained from the comparative study, encampassing such a large number of neurons, suggest that positive sites demonstrated by various methods for phosphatases i. e. by Takamatsu-Gomori technique for alkaline phosphatase, Gomori technique for acid phosphatase and Wachstein and Meisel methods for 5-nucleotidase and ATPase, do reveal real locales of enzymatic activity and are not artifactual in nature. The metabolic significance of the intranuclear distribution of phosphatases has been also discussed.
