Since, however, three fowls which were reported to have been affected and
recovered from the natural disease in the Bhowali flock and one fowl which had
recovered from artificial infection also succumbed to an injection of the same living

was so highly virulent as to break down both natural and artificial immunity. It
is probable that vccination might prove still to be of use, however, against natural
infection.
