lation of fat-cells, a normal process, vacuoles pass from nucleus into cell- 
substance ; Sack (610). — Cell-degeneration in secretion ; Bus (601). — 
Rejuvenescence of cells, marked by preponderance of nucleus over 
cytoplasm, by the undifferentiated state of the latter, and by the 
capacity for rapid multiplication ; Minot (449). — The vegetable cell 
defined as a cellulose chamber inhabited by an energid ; Sachs (609).

Nucleus, recent work regarding; Flemming (203). — Relation of nucleus 
to protoplasmic function. Assimilation in freshwater Rhizopods only 
when nucleus is present ; it conserves the chemical equilibrium and 
structural integrity of the protoplasm ; Le Dantec (383). — Peculiarly- 
branched nuclei in “ houso-forming ” oikoblasts or glandular epidermic 
cells of Appendicular ia ; previously described by Sooliger ; Klaatscii 
(343). — Action of clirom-osmic acid on nucleus; Flemming (204). — 
Chromatophilous character of nuclei; Rosen (591).— Four forms or 
§tages of nuclei in the Foraminifer Calcituba polymorpha ; Sciiaudinn 
(625).— Nuclear changes in cuticularisation ; Chatin (103). — Vacuolated 
nuclei of fat-cells ; Sack (610). — Nucleus and paraplasm of the epidermic 
cells of insects ; Chatin (104).— Structure and division of nucleus in 
Spirochona. Centrosome and nucleolus are homologous structures, which 
vary in function according as they become iutraprotoplasmic or remain 
intranuclear. They consist of microsomes of chromatin; Balbiani 
(17). — Independent movement of chromosomes; Sacharoff (607). — 
Chromatin cannot be regarded as a substance of constant molecular 
structure even in the same organism ; Macallum (415). — Nuclear 
division in Benedenia ; LabbjS (371). — Nuclear polymorphism. Irregu- 
larly contoured and lobed nuclei in some of the epithelial cells of larval 
Salamanders, apparently associated with final stage of mitosis ; Van der 
Stricht (675). — Paranuclear body, in blood-cells of Fishes, Amphibians, 
Reptiles, and Birds — an unstainable sphere with a small staiuable centre ; 
Bremer (70). — Accessory nuclei in various tissues of larval Salamander. 
The occurrence interpreted as an abnormal variation in connection with 
amitosis; vom Rath (555).— Accessory nuclei, one or more, occurring abnor- 
mally, in the cells of various tissues (epithelial, cartilaginous, connective, 
&c.) of larval Salamander, arising by constriction from nucleus. A con- 
tribution to cellular variation and to our knowledge of amitosis ; Rabl 
(544). — Homology of Protozoon and Metazoon nucleus. Except in 
Sporozoa, the Protozoon nucleus retains its membrane during mitosis. 
The division of nuclear structures and functions in Ciliata is unique ;
