Except for their position relative to the explant, it was difficult to distinguish between them. Each cuticle had an epicuticle (a) and a procuticle (b), evidence that they were the products of separate secretory cycles. Once the long-term stability of the experimental system was established, a series of time-dosage tests was made. In the first series, high concentrations of ecdysterone ( to 20 /xg/ml) and short exposures (3 to 24 hr) were used. The minimum number of replicates for each determination was 10, and the results are given in Figure 5. The response to the hormone could be increased by increasing either the concentration or the length of exposure and was reasonably consistent in.
