MEASUREMENT OF THE GROWTH OF TISSUES IN VITRO.
1. A technique has been developed by which two fragments of tissue, put in identical media, can grow at almost the same rate. 2. A method of measuring the growing tissue is described. 3. The differences observed in the rate of growth of two fragments of the 9 year old strain of connective tissue, cultivated in identical media and measured according to this technique, are less than 10 per cent.
