The technic adopted for studying the absorption of unaltered egg protein was similar to that employed in the previous study of fish absorption.1 Egg was excluded from the subject's diet on the day of passive local sensitization, which was accomplished by the intradermal injection of about 0.05 cc. of the K egg serum. The egg meal was usually taken the following morning on an empty stomach. The reaction times were recorded in the same manner as in the previous studies.
The serums used in these studies, K4, K5 and K6, were taken on three different occasions from the same egg-sensitive patient, whose history has already been described in the first communication.2 While samples K5 and K6 were slightly weaker in reagin content than K4, they were all used interchangeably in these studies, as the differences between them were not considered sufficiently great
