ILLUSTRATIONS. 
Fics. 1 to 10.—Ulceration of the first type™ (Delhi boil). 
Fig. 1. Section of the subcutaneous tissue, showing area of necrosis with extensive 
cellular infiltration and fibrin formation. In the fibrin mass just to the 
left of the center the parasites are very numerous. 
2. A portion of the same field as fig. 1, more highly magnified. The parasites 
may be seen as small stained dots and oval bodies, some lying free but 
the majority inclosed in phagocytic cells. 
3. Numerous parasites inclosed in endothelial phagocytic degenerating cells. 
The large phagocytic cell situated just above and to the left of the center 
of the field incloses a parasite showing the larger mass of chromatin and 
also the rod-shaped body. 
4. Large phagocytic cell inclosing at least five parasites, in two of which the 
crescent-shaped, deeply staining mass of pigment is in focus. 
5. Illustrates particularly two of the parasites not inclosed in cells, one lying 
almost in the center of the field and the other, a “seal-ring” form, lying 
below the center. 
6. Single parasite with ring of chromatin to which is attached a short rod. 
Free parasites and others inclosed in phagocytic cells. 
8. Numerous parasites, many in clusters which show no stained chromatin 
mass in focus. The presence of considerable fibrin is evident. 
9, Particularly showing single parasite in the center of the field. 
10. Single parasite more highly magnified (“seal-ring” form). 
11. 12. Leishman-Donovan bodies in a section from the spleen; photograph from 
one of Major Leishman’s specimens; section sent through the kindness 
of Dr. Koch. The parasite in the center of each figure was selected to 
show the sharp outline of the limiting membrane. 
13, Numerous Leishman-Donovan bodies photographed from the same specimen 
as figs. 11 and 12. In this photograph the stained chromatin masses are 
in better focus than the limiting membrane of the parasites, the latter 
here being indistinct, but in other portions of the section much more 
marked. 
Fias. 14 To 18.—Ulceration of the second type (tropical sloughing phagadena). 
14. Gross lesion ef ulceration of the second type, showing patches of pseudo- 
membrane. 
15. Section of tissue from the lesion pictured in fig. 14, showing area of infil- 
tration, necrosis, and fibrin deposit. 
16. Demonstrating area of coagulation necrosis and pseudomembrane. (Weigert 
stain). 
. Showing granulation tissue just below the necrotic area pictured in fig. 15 
(more highly magnified). 
18. Demonstrating proliferation of epithelioid cells about blood vessels.

7 In this case the only photograph obtained of the gross lesion was one repre- 
senting the scar; it is not reproduced, as it shows nothing characteristic.
