Abstract
1. The tatest attempts to connect the chondriosomes with nuclear matter must be considered just as inconsistent as the previous ones.
2. The chondriosomes of the vegetative cells give a negative nueleal reaction and therefore do not contain any thymonucleic acid which is the most characteristic element of the cell nucleus.
Yet the absence of nucleal reaction of the chondriosomes does not depend an their destruction during fixation or the hydrolysis, as a simple restaining of the preparations with iron-hematoxylin or acidfuchsin can prove their presence.
3. Chondriosomes do not contain any “chromatin” and are not in any genetic connection with the Gell nucleus.
