The protoplasm traverses themass of secretion in the form of fine threads, which join togetherto make a wide meshed network, only forming a compact body atthe lower extremity of the cell, in which also the nucleus issituated. II. The Chemico-physical and Morphological Propertiesof the Nucleus. The nucleus is quite as important as theprotoplasm in the economy of the cell. It was first discovered,in 1833, by Robert Brown (I. 5), in plant-cells ; soon afterwardsSchleiden (I. 28) and Schwann (I. 31) made it the found
