Fig. XVI. Triple knots of a small armed (cucurbitina) human 

 taenia, noticed by Werner. 



PLATE SECOND. . 



Fig. I. Fragments of a large human armed (cucurbitina) taenia, 

 which exhibits the joints or articulations as connected with 

 each other, of the natural size, taken from the largest part of 

 the body of this worm. — a, A small mouth opened in one of t!ie 

 lateral papillae. — b c d, Other orifices in the opposite lateral 

 part.' — e, Another little opening in the lateral part. — -f, An- 

 other similar orifice in the opposite lateral part. — g h, small 

 alternate mouths. — 1 23 4 5 6, Small successive openings on 

 one side only — it, small openings on the opposite lateral 

 part, and in this way through the whole length of the worm. 



Fig. II. Two of the largest knots of the great armed human tae- 

 nia. — a h, Papillae with small open mouths, situated on one 

 side only, as in fig. I.— -c, Reciprocal connexion of tlie rings. 



Fig. III. One of the papillae with the small open mouth, which 

 are seen on the lateral parts of the large human armed taenia. 

 The aperture is of the natural size, and Goeze observes, 

 that it seems to be divided by a central line. 



Fig. IV. Three ovaries of the unarmed human taenia (lata), mag- 

 nified by the microscope (no. l,tube A.) Small eggs enclosed 

 may be seen. These ovaries are more pointed than those of 

 the armed human taenia, (cucurbitina.) 



Fig. V. Eggs pressed from one of the small mouths that are seen 

 in the large articulations of the great armed human taenia 

 (cucurbitina). These ovaries are also magnified by the mi- 

 croscope, (no. 6, tube A.) 



Fig. VI. Four eggs of an armed human taenia (cucurbitina,) ex- 

 pressed as above, and viewed with tiie microscope, (no. 1, 

 tube A.) — a bed, Hemispheres, or rather ovaries, in which arc 

 seen an immense quantity of other small eggs. 



Fig. VII. Two other eggs of the same species of worm, magni- 

 fied by microscope (no. l,tube A.) These pretended eggs 

 are in truth, two real ovaries full of eggs.
