DESCRIPTION OF PLATE XVII, 



Illustrating Surgeon T. R. Lewis's paper on the " Micro- 

 phytes of the Blood." The developmental stages of 

 Organisms found in the Blood of Healthy Animals 

 shortly after death. 



Fig. 1. — A tracing of bacilli from a micro-photograph. Magnified 1100 

 diameters. 



Fig. 2.— Growth of ditto into long filaments. Magnified 600 diameters. 



Fig. 3. — Formation of ' spores ' in ditto. 



Fig. 4. — The filaments having become nearly invisible, the ' spores ' only 

 are seen, arranged linearly. Magnified 600 diameters. 



Fig. 5. — Isolated 'spores' in the condition sometimes described as "ger- 

 minating." Magnified 1000 diameters (fig. a, b, magnified 2000 

 diameters). 



Fig. 6 — 8. — The developmental stages of a bacillus below the average 

 dimensions. Magnified 1000 diameters. 



Fig. 9. — Bacilli above the average dimensions. One white and two red 

 blood-corpuscles are outlined in the figure. Magnified 1000 diameters. 



Fig. 10.— Ditto, showing growth into filaments. Magnified 1000 dia- 

 • meters. 



Fig. 11. — Ditto, subsequently undergoing fission. Magnified 1000 dia- 

 meters. 



Fig. 12. — Spore-like bodies which formed in a portion of the filaments 

 delineated at fi^;. 10. Magnified 1000 diameters.
