    In tlie lungs of tlie slieep a variety of this worm is fre- quently found occupying whitish tuberculous-looking spots, commonly mistaken for tubercle (from which the lungs of the sheep appear to be perfectly exempt). The young of the parasite migrate to the small bronchial tubes, and occasion considerable irritation. The drawing represents one of the so-called tubercular masses from the lung of a sheep, and shows the worm coiled up amidst a quantity of exudation matter, undergoing cal- careous degeneration.
