EXPLANATION OF PLATE XI. 
Except when otherwise stated Mann’s methyl-blue eosin stain has been employed. 
The preparations were all drawn with the aid of a camera lueida, eyepiece No. 4, 1/12 
apochromatic oil immersion, 11mm. tube extension (Zeiss). 
Note. In the authors’ original crayon drawings, the cell protoplasm appears pink, 
the nucleus and neurogleal cells blue, the nucleoli and Negri bodies etc. red, except in 
figs. 13 and 14 where they are black. In fig. 2 the vesiculated mass (h) appears yellow 
and in figs. 10 and 11 the nucleoli (a, a') appear green. En. 
Fig. 1. A cell from the fascia dentata of a guinea-pig killed with Russell’s Viper venom, 
showing Negri bodies, (a) fragmented nucleolus; (6) vacuolated Negri body; (c) minute 
faintly staining cytoplasmic particle. 
Fig. 2. Human cortical cells from a hydrophobia case, (a) nucleolus showing pink ring 
and yellow centre; (i) yellow vesiculated mass. 
Fig. 3. Bullock infected with rabies; ganglion cell from the hippocampus major, 
(a) nucleolus; (6) large vacuolated Negri bodies wuth primary and secondary vesicles.
