GLOSSARY 337 



Idant, the hypothetical unit resulting from tlie successive aggregation of biophores, 



determinants, and ids. Identified by Weismann as the chromosome. (Weis- 



MANX, 1 891.)

cell; the same as biophores. (O. Hertwig. 1893.) 

 Id'ioplasm (I'Sios, one's own; 7rAao-/Aa, a thing formed), equivalent to the germ- 

 plasm of Weismann. The substance, now generally identified with chromatin. 



which bv its inherent organization involves the characteristics of the species.

thread-work. (Flemming, 1882.) 

 Interzonal fibres ('• Filaments reunissants '' of Van Beneden. " Verbindungs- 



fasern " of Flemming and others). Those spindle-fibres that stretch between 



the two groups of daughter-chromosomes during the anaphase. Equivalent in 



some cases to the central spindle. (Mark., iS8r.) 

 Iso'tropy (i,'cros, equal; rpoTrr;, a turning), the absence of predetermined axes (as 



applied to the egg). (Pfluger, 1883.) 

 [Ka'ryaster] {Kapvov, nut, nucleus ; see Aster. 2). the star-shaped group of chromo- 

 somes in mitosis. Opposed to cytaster. (Flem.mixg, 1882.) 

 Karyenchy'ma (Kapvov, nut. nucleus; ev, in; x^^/x-o's, juice), the "nuclear sap." 



(Flemmixg, 1882.) 

 Karyokine'sis (Kapvov, nut, nucleus; KtVr;o-ts, change, movement), the same as 



mitosis. (Schleicher. 1878.) 

 [Karyoly'ma], the "karyolytic" (mitotic) figure. (Auerbach, 1876.) 

 Ka'ryolymph. The nuclear sap. (Hackel. 1891 .) 

 [Karyo'lysis] (Kapvov. nut, nucleus; Avert?, dissolution), the supposed dissolution 



of the nucleus during cell-division. (Auerbach, 1874.) 

 [Karyoly'tic figure] (see Karyolysis). a term applied by Auerbach to the 



mitotic figure in living cells. Believed by him to result from the dissolution of 



the nucleus. (Auerbach. 1874.) 

 Karyomi'crosome (see Microsome), the same as nucleo-microsome. 

 Ka'ryomite. the same as chromosome [? Schiefferdecker]. 

 Karyomi'tome (Kapvov, nut. nucleus; p.LTo}p.a, from /AtVos, a thread), the nuclear 



as opposed to the cytoplasmic thread-work. (Flemmixg. 1882.) 

 Karyomito'sis (Kapvov, nut. nucleus; see Mitosis), mitosis. (Flemmixg, 



1882.) 

 Ka'ryon (Kapvov. nut. nucleus), the cell-nucleus. (Hackel. 1891.) 

 Ka'ryoplasm ( Kaovoi/. nut. nucleus ; TrAao-jua. a thing formed), nucleoplasm. The 



nuclear as opposed to the cytoplasmic substance. (FLE^^MIXG. 1882.) 

 Ka'ryosome {Kapvov, nut. nucleus; o-w/xa, body), i. Nucleoli of the "net-knot" 



type, staining with nuclear dyes, as opposed to plasmosomes or true nucleoli. 



(Ogata, 1883.) 2. The same as chromosome. (Platxek. 1886.) 3. Caryo- 



some. The cell-nucleus. (Wata.se, 1894. )
