That this is not the case, however, is shown by the fact that the value on the 25th day does not vary appreciably from that of the 72nd day. The same type of result was obtained for all of the six distances shown in figure 1, namely, for the distances posterior end to parabasal body, parabasal body to nucleus, nucleus to anterior end, anterior end to end of T Lencjth PIG.

41. lappuse - As a matter of record it seems advisable to bring up to date and summarize the chief results derived from the writer's main pedigree culture of Paramecium aurelia. This culture, designated Culture I, was started on May 1, 1907, by the isolation of a "wild" individual which was found in a laboratory aquarium.1 The original specimen was placed in about five drops of culture fluid on a glass slide having a central ground concavity, and when this animal had produced four individuals, each of these was...
44. lappuse - However, at the formal termination of the experiments in 1915, I was reluctant to discard the race and was tempted to keep it under control but without such exacting daily observation and recording of the daily division rate. In this manner it has been maintained up to the present (December, 1920). But, from time to time, thirty-day tests have been made of the vitality of the race under the former rigid culture conditions, and in each case the same general average division rate has been revealed...
