EXPLANATION OF PLATE XXVII. 
All figures were outlined with Abbe-Zeiss camera lucida, using 
2 mm. apochromatic homogeneous immersion objective and 
compensating oculars 8 and 12 of Zeiss. Magnification 2,000 
diameters approximately, except where otherwise stated. 
The chief stains used were iron haematoxylin, Giemsa, or 
Romanowsky after wet fixation. 
The figures represent T. rhodesiense , as seen in rats, except 
where otherwise indicated. 
Fig. 1 represents the formation of latent (non-flagellate) body 
from trypanosome in heart blood. 
Figs. 2-5 represents latent bodies, with remains of trypanosomes 
around or near, from heart (fig. 4) and lungs. 
bigs. 6, 7. — Oval latent bodies, each with nucleus and blepharoplast 
(kinetonucleus), from lung of rat and peripheral blood 
of guinea-pig respectively. 
Figs. 8-16.—Various forms of latent bodies — from liver, heart, 
spleen, lung (figs. 8-11); of T. gambiense in peripheral 
blood of rat (fig. 12); from peripheral blood (fig. I 3 )> 
lung, and heart respectively. 
Figs. 17-20.—Rounding, herpetomonad-like forms, all from 
peripheral blood of guinea-pigs. Fig. 19 °f ^' 
gambiense. 
big. 21. Broad trypaniform parasite from blood of guinea-pig- 
b ig. 22. Latent form of T. gambiense from lung of rat. 
Figs. 23-24. — Possible division forms of latent bodies of 
T. rhodesiense from heart and lungs of rats. Fig- 24 
magnified 1,350 diameters. These forms are rare. 
Fi gs. 25, 26. — Pyriform latent bodies, each with nucleus and 
blepharoplast. Fig. 25, of T. rhodesiense from blood 
of guinea-pig ; fig. 26, of T. gambiense from blood of 
rat.
