"Paramecium. I, transverse fission; 2-5, stages in conjugation. The meganucleus gradually disintegrates during the process and the micronucleus by two successive divisions forms four micronuclei. Two of these disintegrate. One of the remaining micronuclei (n3) in each animal passes into the other Paramecium and unites with the stationary micronucleus (n4), thus fertilizing it. Later a new meganucleus is formed in each animal by the division of this body. Nucleus n3 is often smaller than n4 and may represent the male element." -Galloway, 1915
