On the anatomy, decay and development of the trichina spiralis. "From the Transactions of the Pathological Society for 1854." DESCRIPTION OF PLATE XIII.

The figures illustrate Dr. Bristowe’s (and Mr. Rainey’s) Observations on the Anatomy of the Trichina Spiralis. Page 274.

Fig, 1. Trichina spiralis. a a a integument; b b b. muscular layer; c mouth; d, anus; e. oesophagous; f f. alimentary canal; g. funnel shaped portion, with pyriform bodies at its base; h. tube connected with reproductive process; i. yellow deposit in it; j j. space between mus- cular layer and parts internal to it. It terminates above in minute points.

Fig. 2. The same less magnified, intended to show better the relative size and situation of parts, The letters indicate the same structures as in the preceding.

Fig. 3. The same with its surface in focus, to show one of the longitudinal muscular bands,

Fig. 4. Fragment of the anterior part of the worm, with the alimentary canal protruding, and apparently exhibiting a central tube.

Fig. 5. Fragment of posterior part of worm. The generative tube, h protrudes, and its cellular structure is exhibited. A portion of the alimentary canal is likewise exposed. At this part it is contracted, and consists apparently of a structureless membrane studded with refractive globules.

Fig. 6. Generative tube acted on by acetic acid. The cells are heaped together, and the basement membrane is seen.

Fig. 7. Integuments of the lower part of the worm from which the entire contents have been separated by endosmose. The crenate appearance lost, and the prolongation into the anus is visible.

Fig. 8, Appearance frequently presented by fat formed either free among
