  1. 1. The number of length measurements between all neighboring pairs of structures. 2. Determined from curves such as those shown in Figure 7. 3. Obtained by inoculating at four locations in the Petri dish rather than at random. 4. The values between which the mean link length will lie in 99% of populations. 5. Fiber fragments were dispersed by vortexing in 10 ml fresh TB prior to transfer. 6. Fiber fragments were transferred by toothpick directly from the parent culture.
