Abstract
LARGE numbers of elementary bodies were found by Stamp et al.1 in the fœtal membranes from sheep after experimental transmission of enzootic abortion in ewes; these were described as having the morphological and staining properties of a rickettsia or a virus of the psittacosis-lymphogranuloma group. The exact nature of the agent remained uncertain, although later studies2 on its development in the chorio-allantoic membrane of fertile eggs suggested that the latter relationship was the more probable. The following experiments were made in order to determine whether the virus of enzootic abortion in ewes has antigenic properties which would define its position from this point of view.
