No significant differences were noted in acceptance of autografts between animals injected with skin emulsion and control emulsion. 2 ) Irritancy tests using scraping and burning of the skin did not produce different results in the test animals and the control animals. 3 ) Under the conditions of these tests no autosensitization to skin could be demonstrated in guinea pigs. 1.
