The cultivation of living tissue. Part 1.

Tissue culture; living cells cultivated in vitro shown in time-lapse. There is a long explanatory intertitle at the beginning which includes how the images are captured. This is then demonstrated. Embryonic cells are shown in time-lapse (speeded up 960 times). Wandering cells and fibroblasts; cell division. There is a hand drawing of a fibroblast, with annotations. Daughter cells. Chromosome arrangement. Phagocytosis; dgenerative culture of the central nervous system (note; there is a clock in the corner to illustrate time passing). Dark ground illustration; polarisation of the sequence illuminating the internal cellular structure. End of Part 1.
