A microscopic investigation of the faeces of cattle was undertaken in search of possible cyst forms of the numerous species of ciliates which inhabit the rumen and reticulum of these animals. Of the various workers who have searched for the cysts of these protozoa only one, Liebetanz (1910), reports success. His technique, however, was so open to adverse criticism, and his figures so unconvincing, that it is doubtful if even he really saw cystic forms.
