Abstract

The fine structures of the eosinophils of the peripheral blood obtained from 5 clinically normal sheep were examined under an electron microscope. The results thus obtained were summarized as follows : 1) The cells with nuclei of two to four lobes were most commonly observed on the cut planes. 2) The nuclear lobes of the cells showed a clear maculous appearance with two distinct densities, one light and the other dark, according to the amount of the chromatin condensation. 3) On the basis of the internal structures of the specific granules, they were classified into six types and the basic type of the granules seemed to be those containing middle plates. 4) A small number of mitochondria measuring 0.3 by 0.7μ on the average, Golgi complex, a number of smooth- and a few rough-surfaced endoplasmic reticulum, and some other micro-organelles were observed in the cytoplasm.
