On the anatomy, decay and development of the trichina spiralis. "From the Transactions of the Pathological Society for 1854." DESCRIPTION OF PLATE XIV. The figures illustrate Dr. Bristowe’s (and Mr. Rainey’s) Observations on the Degeneration of the Trichina Spiralis. Page 274. Fig. 1. Trichina cyst. a. polar fat; b b. laminated walls; c. granular mat- ter inside; d. worm. Fig. 2. Fragment of one of the lamina, showing its fibrous appearance. Fig. 3. Material filling the space between the worm and the cyst wall.

Figures 4 to 7 illustrate the process of decay. Fig. 4. The worm only is here affected. In some parts it is collapsed; in others its interior is studded with opaque masses of earthy granules; and towards its anterior extremity the earthy deposit forms a tuber- culated refractive mass. Fig. 5. The worm only is affected; but, in addition to being infiltrated with earthy matter, it is broken into a number of fragments. Fig. 6. In addition to degeneration of the worm, the cavity of the cyst is occupied by numerous refractive globules of carbonate of lime. Fig. 7. The earthy deposit here forms an irregularly ovoid concretion, which fills the cyst; and on one side of which remnants of the Trichina
