I. GENERAL SUBJECTS. 
c. Nucleus , Nucleolus , Centrosome. 
Structure of the nucleus ; Catterina (110). — Minute structure of 
nucleus ; Korschelt (375). — Basic substances of the nucleus : Kossel, 
(37G). — Structure and division of the nucleus; Van deu Stricht (G51). 
— Structural change in the resting nuclei of Protozoa ; Greenwood 
(280). — Conjugation of epithelial nuclei in intestine of terrestrial Iso- 
pods ; Sciiimkewitsch (611). — Tension-law of the centered system; 
Heidenhain (314). 
Compound nucleoli in ova of Annelids, &c. ; Michel (462). — The so- 
called Nebenkern in the male sex-cells of insects ; Erlanger (205). — 
“ Nebenkern ” in spermatocytes of Helix ; Bolles Lee (407). 
General considerations as to spindle and centrosome ; Erlanger (207). 
— Structure of protoplasm and centrosome ; Erlanger (206). — Occur- 
rence of centrosome and sphere in nerve-cells of a worm (one of the 
family Maldanice). Doubt as to whether the apparent centrosome is a 
true centrosome ; Lewis (412). — Centrosome and attractive sphere of 
leucocytes of newt, instantaneously differentiated by a mixture of mala- 
chite and saffranin greens. Regarded as having close relations with 
nucleus, perhaps differentiations of it. Regarded as presiding over 
division, but also as having to do with plasmic movement and cell-nutri- 
tion ; Marchesini (439). — Centrosomes are specific essential parts of 
the cell, morphologically independent and persistent il organs,” serving as 
insertion centres for the radii ; Kostanecki & Siedlecki (379). — Cen- 
trosomes in fertilized ovum of sea-urchin ; Kostanecki (378). — Centro- 
somes in gangliou- and cartilage* cells; Schaffer (605). — Centrosome and 
astrocoel of Falgur ; MacMurricii (436). — R61e of centrosome and 
sphere in forming the spermatozoon in Mammals; Niessing (498,499). 
— Astrosphere is a purely topographical conception, an area free from 
vitelline substance ; Kostanecki & Siedlecki (379). — Production of 
artificial astrospheres ; T. H. Morgan (485). — Behaviour of attraction- 
spheres in division of spermatocytes of Salamander ; Rawitz (557). — 
Archoplasm in Boveri’s sense cannot be sustained ; Kostanecki & Sied- 
lecki (379). 
d. Cell-Division. 
Cell-division, general account ; Wilson (720). — Current problems con- 
nected with cell-division ; Farmer (211). — Physiology of the division of 
cell and nucleus; Boveri (80). — Attempt at an explanation of the 
indirect division of cell and nucleus : Rhumrler (564). — Interpretation 
of karyokinetic figures ; Gallardo (245). — Karyokinesis in developing 
ova of Fulgur ; MacMurricii (436). — Significance of direct cell-division: 
it is more rapid than indirect division, and thus important in regenerative 
processes ; Balbiani & Henneguy (29). — The question of amitotic 
division; Rein hard (562). — Theory as to origin of multiple mitosis; 
Norman (500). — Experimental production of irregularities in karyo-

hedgehog ; Floderus (233).
