Plate XVIII, fig. 1.—The essential structure of an elongated kunkur, partially detached from
              the mother tissue is to be seen. Eosinophil leucocytes are the most predominant cells
              in this growth. Longitudinal section of the worm larva, with its transverse striation
              can be seen occupying the blood vessel, which forms the nucleus for the production of
              this kunkur.

Fig. 2.—Section of a bursati growth, showing a healthy worm in a healthy vessel. Only the
              perivascular lymphocytic reaction is in evidence here. This stage is followed successively
              by the stages represented by PI. XIX, fig. 1 and PI. XVIII, fig. 1.
Plate XIX, fig. 1.—Longitudinal section of a larva lying free in a blood vessel. Diffusive
              action of the toxin can be judged by the homogeneous appearance of the border around
              the vessel.

Fig. 2.—Photograph of a Habronema larva in a bursati section. The posterior end of the worm
              is directed to the right, the anus being easily visible.

Fig. 3.—Photograph of the anterior end of a Habronema larva, obtained from a bursati section.
              The cylindrical vestibule is clearly seen.
