PLATE 29. 
Fig. 1. Lymph from pustules of sheep-pox, kept in a sealed capillary tube. (Examined 
March 10, 1874, with Hartnack’s ocular 3, objective 9.) 
1 . Transparent masses of various sizes, containing granules, some of which 
are small, pale, and indistinct, others large and shining. 
2. Transparent spheroid bodies containing necklaces. 
3. Highly refractive Micrococci in proliferation, forming dumb-bells, 
Sarcina-Wke structures, and small colonies. 
4. The same, between decolorized blood-disks. 
5. Bacterium. 
6. Colonies of Bacterium termo. 
7. Shining Micrococci imbedded in a greenish matrix, some being sur- 
rounded by a thin membrane. 
8. Groups of bodies similar to those in 2 and 3. 
Fig. 2. Similar preparation to fig. 1, but which had been kept for 24 hours in the 
incubator. (Examined March 11, with Hartnack’s oc. 3, obj. 10, immersion.) 
1 . Network of fine filaments beset with Micrococci ; transparent spheroids 
like those in fig. 1, 2. 
2. Network of filaments more defined, with spheroid bodies budding from it. 
3. Part of the same preparation, kept in the incubator till March 17. 
Fig. 3. Lymph from pustule of sheep-pox kept for 24 hours at a temperature of 32° C. 
(Examined March 25, with Hartnack’s oc. 3, obj. 8.) 
1. Homogeneous sporids, some free, others contained in pus-corpuscles. 
The same sporids of a paler colour, containing one or two Micrococci. 
2. Micrococci forming necklaces. 
3. The same in groups. 
4. The same in colonies connected by filaments of various lengths. 
5. Diagrammatic representation of the relation of 1 to sporids and of 2 
to Micrococcus ( Cryptococcus of Hallier). 
Fig. 4. Preparation from a vertical section of the thickened epithelium of the peripheral 
part of a pock three days after its first appearance. (Hartnack’s oc. 3, 
obj. 7.) 
A. Horny layer. 
B. Superficial layers of the rete Malpighii. Near the poles of the nucleus
