134 H. CHARLTON BASTIAN ON THE DRACUNCULUS, OR GUINEAWORM. 
Fig. 32. Posterior extremity of worm (twice the natural size): (a) intestinal canal; (4) posterior portion 
of uterus; (c) posterior ovarian tube ; (d) termination of intestine in concavity of tail, mid- 
ventral region. 
Fig. 33. Different portions of alimentary canal and its peritoneal sheath. 
1. Small portion of sheath of œsophagus : (b) showing epithelial cells on its surface ; and | 
(a) the small included cesophagus. 
2. (b) constriction in peritoneal sheath at junction of esophagus with intestine ; (d) fat- 
cells surrounding intestine. : 
3. Portion of middle part of intestine, which has been compressed by the distended uterus, 
showing obliteration of the fatty liver(?)-cells, and presence of epithelial cells on the 
peritoneal sheath. 
4. Terminal portion of intestine, with sheath and liver-cells surrounding it up to the 
extremity. (x about 150 diam.) 
Fig. 34. Anterior termination of uterus, with ovarian tube attached: (a) abrupt termination of uterus ; 
(b) ovary; (c, c) young accidentally found in ovary. 
Fig. 35. Precisely similar posterior termination of uterus, with ovarian tube attached. (x about 80 
am. 
Fig. 36. Portion of peritoneal covering of genital tubes, with scattered various-sized epithelium-cells on 
its surface. 
Fig. 37. Reticulated fibrous network of elastic tissue from the second coat of the uterus. 
Fig. 38. Very fine longitudinal muscular fibres, composing the third coat of the uterus. (Figs. 36, 37 
&.38 x about 400 diam.) 
Figs..39-55. Showing various stages in the development of the young, from the smallest pseudovum 
recognizable to nearly the full size attained by the young, in which, however, only the 
rudiments of the anterior part of the alimentary canal can be detected. 
Fig. 56. The various forms of young worms, magnified about 100 diam.: (a) granular débris mixed with 
young; (4) peculiar and regular corrugations produced in some of the young, perhaps by the 
action of the spirit in which they were preserved. 
Fig. 57. One of young, seen sideways, showing, (a) circular ruge; (b) esophagus; (c) stomach; 
(d) cecal termination of intestine; (e) single sacculus, with central aperture; (f) rudiments 
of some organ, perhaps genital? (g) termination of abdominal cavity and circular ruge; 
(4) linear tail. 
Fig. 58. Worm seen in same position, showing reflection of terminal portion of intestine. 
Fig. 59.. Worm showing both lateral sacculi. 
Fig. 60. Worm in same position as last, showing minute bilobed projections from the lateral sacculi. 
(Last four figures all x 500 diam.)
