BXPLANATION: OF PLATE. 20, 
Illustrating Dr. Row’s paper on “The Development of the 
Parasite of Oriental Sore in Cultures.” 
|All figures are drawn with the camera lucida to a magnification of 
2000 diameters from preparations stained with Giemsa’s stain. | 
Fie. 1.—lLarge macrophage containing numerous parasites, from a 
smear of the Juice of the sore. 
Fra. 2, a—f—F ree parasites from the same smear; ad-c, young forms 
with micronucleus and macronucleus closely apposed; d-f, parasites 
probably set free from a macrophage. 
Fia. 3, a-g.—F ree parasites from a smear of an old case, showing 
various shapes of the body and conditions of the nucleus; e, g, dividing 
forms. 
Fie. 4.—Mass of parasites from a smear of a culture of forty-eight 
hours’ standing, showing various shapes and sizes of the parasite. 
Fra. 5, a~c.—Three flagellated individuals from the same preparation 
as the last figure. 
Fra. 6, a7.—Flagellated Herpetomonas-forms from a smear of a 
culture of seventy-two hours’ standing; a-e, various forms of single 
flagellates ; f-7, parasites in groups and pairs. 
Fic. 7, a-o.—Parasites from a smear of a retarded culture of twenty- 
four hours’ standing ; various stages of the development are seen. Some 
parasites, such as the two small ones in g, have not developed at all; 
others, such as k and 1, have developed much further and are dividing. 
Pia. 8, a-m.—Parasites of a smear of a retarded culture of forty-eight 
hows standing. «a, division into a stout and a slender form; b-d, 
division of stout forms ; e-7, division of slender forms; j, k, groups show- 
ing various stages of development; inj is seen a parasite not advanced 
beyond the initial stage; /, a group showing a pair of slender forms, 
recently divided off, and a pair of stout forms in the act of dividing; m, 
two pairs of slender forms (one dividing) with flagella growing out.
