In addition, samples of sera obtained from all the adult animals in the
stud submitted to an agglutination test against antigens made from S. abortus
equi and the coliform organism isolated from the foetus of mare Affable (Ap-
pendix 1). Of the 72 animals so tested, none gave a positive reaction
against S. abortus equi. Five of these, however, gave a suspicious titre against
the coliform organism, showing a titre of 500. However, none of the aborted
animals were among those giving this suspicious reaction.

To sum up the results of the bacteriological examinations, in no instance
was S . abortus equi associated as an etiological' factor. Out of twelve lots of
material examined, only three were positive for Streptococcus pyogenes, and
