A long, massive fibrin filament such as seen in embolism. This is a com- 

 plication element. 



20. Consumptive and Eheumatic blood, y inch, 200x. Massive embolic 

 filament outside and filaments inside the vacuoles or gas bubbles. Kept 

 specimen. 



21. Ditto, y inch, 200x. Fibrin filaments. Fat or soap (?) ma.ssive fila- 

 ment ; spores. Note the red discs drawn into pointed double-enders by the 

 fibrin filaments in dying. 



22. Syphilitic blood, 1-lOth inch. For comparison. Free oih', fat glob- 

 ules from beneath the skin — an early sign of fatty ills, spores hazy because 

 auto-mobile. 



23. Another ca?e like 19. ] inch. 



24. Syphilitic and consumptive blood ; ] inch. Mycelium of crypta 

 syphilitica ; spores ot tuberculosis. 



25. Better print of 19. 



26-30. Syphilitic blood for contrast ; ] and 1-lOch inch. The comparison 

 of the photos of the ] inch and of the highest powers, favors the latter. 



31. Consumptive blood ; l-50th inch. Faintly shows fibrin filaments. 

 Spores. 



32. Ditto ; l-75th inch. Enlarged white corpuscle with spores inside and 

 out. 



33. Ditto; 1-lOth inch. Spores and spore collects. Vacuole or gas bub- 

 bles. Below it a gravelly matter, foreign. 



34. Ditto ; 1-lOth inch. Large air bubbles or vacuoles, fibrin filaments. 

 Spores. 



35. Ditto. Red corpuscles pale and ill outlined ; spores and collects 

 abundant. 



36. Consumptive syphilitic blood ; 1-lOth inch objective. Two white cor- 

 puscles enormously enlarged. Spores. 



37. Consumptive blood ; 1-1 0th. Spores and spore collects oi my coderma 

 aceti. 



38. Ditto ; 1-lOth, spores. Large vacuole or bubble. Eed discs drawn 

 out. White corpuscle. 



39. Ditto. Bubbles or vacuoles. Three white corpuscles with amoeboid 

 prolongations. 



40. Ditto. Attempts at rouleaux. Several white corpuscles of varying 

 sizes, single and double spores. 



41. Ditto ; l-50th. Spore collect and sjwres. 



42. Ditto ; 1-lOth. Fat globules in with the spores aud collects. 



43. Ditto. Fibrin filaments. Enlarged white corpuscles, simres. Der. 

 mal epithelia invaded with spores. 



44. Do ; l-16th inch. Spores and red discs. 



45. Do ; l-16th inch. A poor photo, but instructive. Spores and chains 

 of spores. 



46. Morphology of skin ; scraping. Study of foreign substances sometimes 

 lound in the blood by accident.
