SPIROCHATA BALBIANIL AND SPIROCHATA ANODONTH, 73 
Fic. 36.—Specimen in which both ends are curled. Billet’s stain. x 1500. 
Fie. 37.—Parasite showing well-defined nucleus of chromatin rodlets, 
and the presence of a membrane. Billet. x 1500. 
Fic. 38.—Parasite, killed and fixed, while rapidly moving, by osmic vapour. 
Exhibits numerous sinuosities in body outline and in winding of the mem- 
brane, which is a right-handed helix. Chromatin rodlets well stained. A 
rather long parasite. Billet’s stain and tannin orange. x 1500. 
Fre. 39.—Parasite moving less rapidly than the last when killed and fixed. 
Membrane rather closely adherent to the body. Billet’s stain. x 1500. 
Fic. 40,.—Specimen in process of longitudinal division. The membrane 
has already divided into two, and the chromatin rodlets have divided each 
into two, the daughter chromatin masses being peripherally disposed in the 
parent form. That the basal granules are double can just be discerned. 
Billet and tannin orange. x 1500. 
The pointed end of 8. anodonte, terminating as a fine periplastic process, 
staining pink (or chromatin-like) with Giemsa’s or Billet’s stains, is well 
shown in these forms (figs. 35—40). It hardly seems to be a strict flagellum, 
for it is stiff. It is, however, very small and fine.
