Karyokinetic problems ; Strasburger (673). — Atlas ; Wilson (761). — 
Relation between mitosis and amitosis; Krompeciier (364).— Multiple 
indirect division ; Krompecher (365). — Mitosis of multinucleate cells ; 
Krompeciier (364).— On the nature of the spindle-figure in karyoki- 
nesis ; Eismond (178). — Retrogression of the karyokinetic spindle: 
observed in spermatogonia and spermatocytes of the snail. A compact 
body unites the daughter cells, and the bridges may persist for several 
successive cell generations; Bolles Lee (51). — Mechanism of cell- 
division ; Druner (161), Flemming (206). — Confirmation of Heiden- 
hain’s theory of “cellular mechanics ” ; Reinke (572). — The question of 
amitosis ; yom Rath (555). — Cells which once divide by amitosis never 
again divide by mitosis. The number of successive amitoses is narrowly 
limited. Regeneration by amitosis has not been proved. Amitoses are 
especially common in intensely assimilating, secreting, or excreting cells. 
Amitosis indicates more or less degeneration, and though simpler than 
mitosis cannot be regarded as primitive ; yom Rath (555). — Amitosis : 
summary of recent work ; Flemming (203). — Amitoses ; Bracs (69). 
— Mitosis and amitosis : an attempt to explain the phenomena of 
division ; Kobelt (348). — Amitosis plays an important part in the 
multiplication of cells, both in the young stages and in the older 
ovarian follicles of Nepa cijterea and other Hemiptera. In the 
younger egg-chambers abupdant mitoses, but no transitional forms. 
Other cases of functional importance of amitoses ; Preusse (537).— 
Amitotic division, along with karyokiuesis, in the intestinal epithelium 
of Ophryotrocha ; Korschelt (352). — Amitotic division in germinal 
vesicle of hedgehog ; Floderus (208). — Regression of karyokinetic 
spindle ; Bolles Lee (51). — Chromosome reduction : essentially similar 
in plants and animals ; Moore (467). — Intercellular ligament ; Bolles 
Lee (51). — Intercellular bodies in developing ova of Teleosteans ; 
Baffaele (546). — Variation in cell-division in one and the same species ; 
Farmer & Moore (187). — Division of nucleus in vegetative state of 
Sphcerozoa ; Mitrophanow (451). — Heterotypic nuclear divisions in 
animals and plants, e.g., in spermatogenesis of Triton, and in pollen 
mother-cells of lilies : their essential similarities ; Farmer & Moore 
(187). — Peculiar mitosis in young oocytes of Salamander, observed when 
captive specimens were leaving the water : possibly the phenomena re- 
present the introductory phases of premature and abnormal directive 
divisions ; Meves (443). — Multiple cell-division is not uncommon nor 
abnormal : the indirect nuclear division may be linear (binary), in a 
plane (into three), in three dimensions (multiple), but always regularly 
and definitely : hypertrophy seems to favour multiple division; Krom- 
pecher (365). — Peculiar division of Ceratium hirundinella , neither direct, 
nor mitotic : no longitudinal cleavage of chromatin elements, nor an 
achromatin spindle ; Lauterborn (380). — Proliferation of colls ; Foa 
(210). — Stimulus to cell-multiplication, minute quantities of lecithin 
added to the medium; Danilewsky (135). — In Amoeba, binucleata ; 
£chaudinn (627). — In Ophryotrocha puerilis ; Korschelt (352).— In
