Sincethis is incapable of retaining the dyes of staining solutions, it isevident that it consists chiefly of linin, upon which only a fewnuclein granules are deposited. One large nuclein body is presentin the framework ; occasionally, however, it is divided into twosmaller ones. That this body really consists of nuclein is provedpartly by its behaviour towards staining solutions, but chiefly bythe fact that during nuclear division its substance breaks up intogranules, thus forming the nuclear segments.
