BERGH’s second paper?° on the formation ? ire chromosomes deals 
with the behavior of the chromatin from the telophase of the last division in the 
sporogenous tissue up to the strepsinema stage of the first mitosis in the micro- 
spore mother-cell. In a very early prophase of the first mitosis in the mother- 
cell, slender filaments are formed from the chromosomes of the sporogenous 
cell. Synapsis then takes place and at its close the filaments appear a5
