Before use in a test, a section of pig skin was thawed, destubbled using a disposable razor, and defatted using a scalpel. The plates were graded to indicate the extent of organism growth in the imprint. Standardize them by calculating specific gravity and noting the percentage from the table given in B.

Mature adult pig hides from freshly killed pigs were obtained from a slaughterhouse.

Weight readings were made each 30 seconds galeniccals a six-minute period demonstrating uniformity of loss over this period.
