EXPLANATION OF FIGURES 
Complexes from atypical individual 2525 
93 Lateral view of first spermatocyte spindle showing complete complex of 
eleven tetrads, plus the accessory (x) plus the extra dyad (S). 
94 Oblique view of first spermaocyte complex with the extra tetrad (S). 
95 Polar view of normal first spermatocyte complex without any extra 
elements. 
96, 98, 99, and 101 Spermatogonial metaphases of twenty-four dyads. 
97 Spermatogonial metaphase of twenty-five dyads. 
100 Second spermatocyte metaphase (polar view) of twelve dyads. 
102 Lateral view of second spermatocyte anaphase with twelve monads 
passing to each pole. 
103 Polar view of second spermatocyte metaphase of thirteen dyads. 
104 Lateral view of second spermatocyte anaphase with thirteen monads: 
passing to each pole. 
(Note:—The complexes shown in figures 102 and 104 were each in two sections. 
and the chromosomes are drawn displaced somewhat from their natural positions.
