John Muirhead Macfarlane,

Nutrition, Genetics, and Disease

In the present paper I propose extending my previous observations “On the Structure and Division of the Vegetable Cell.” I have shown that a nucleolus and nucleolo-nucleus (at Professor Rutherford's suggestion I now propose terming this the endonucleolus ) are essential, and in most cases evident, parts of every growing vegetable cell, and that the division of the endonucleolus very probably precedes that of the nucleolus, just as division of the latter undoubtedly precedes that of the nucleus, in all the cases investigated.
