Excerpt from The American Journal of Anatomy, Vol. 30: January, 1922-July, 1922 I have also found in the spermatids a collection of granules which seem to be preserved best in the absence of acetic acid. During the formation of the acrosome these granules are arranged in a circle around the acroblast and lie close to the nuclear membrane. This arrangement is a constant and striking one (fig. The nature and fate of these granules are not known. Possibly they are related to the chromatoid bodies of other animals. They may be related to the granules previously men tioned as occurring in the spermatocytes. A more critical study of these granules will be undertaken on new material.
