DESCRIPTION OF PLATES 
Plate: II. Fig. i.— Cysticercus ovis from lamb which had been fed eggs of Taenia ovis 
(lamb No. i, p. 23). 
Fig. 2.— Cysticercus cellulosae. The cysticerci have been extracted from 
their cysts. Natural size. (From photographs.) 
Fig. 3.— Taenia ovis. This tapeworm was developed by feeding Cysti¬ 
cercus ovis to a dog (dog No. 6, p. 23). One-half natural size. (From 
a photograph.) 
Fig. 4.— Taenia hydatigena (T. marginata) from an imported sheep dog. 
Fig. — T. hydatigena (T. marginata) from a dog (dog No. 2, p. 21) which 
had been fed Cysticercus tenuicollis . In figure 5, diagonally above and 
below, are shown two small specimens of C. tenuicollis developed in a 
lamb (lamb No. 7, p. 25) by feeding segments of T. hydatigena. One- 
half natural size except the two cysticerci, which are shown natural 
size. (From photographs.) 
Ill (colored). Figs. A and B. —Portions of muscle of sheep showing Cysticercus 
ovis (undegenerated) in situ. 
Fig. A .—Section of hind leg showing two “deep” cysticerci. Fig. B — 
Hind leg showing three “superficial” cysticerci. (Two-thirds natural 
size. Original.) 
Figs. C and D .—Heart and portion of diaphragm of sheep showing Sarco- 
cystis nodules likely to be mistaken for degenerate cysticerci. (Two- 
thirds natural size. Original.) 
Fig. E .—Sheep heart showing numerous small degenerate cysticerci 
( Cysticercus ovis .) (Two-thirds natural size. Original.) 
IV. Fig. 1.—Carcass of sheep showing a degenerate cyst of Cysticercus ovis at 
the point indicated by the penknife. (From a photograph by Dr. T. 
White and Dr. A. English.) 
Fig. 2.—Degenerate cysts of Cysticercus ovis in muscle of sheep; portion 
of carcass shown in Plate III, figs. A and B. About natural size. (From 
a photograph by Dr. T. White and Dr. A. English.)
