FIG. 26. BODIES OBSERVED IN A SCRAPING OF A TERTIARY SYPHILITIC 

 LESION. 1, An ordinary squamous epithelial cell devoid of move- 

 ment ; 2, a similar cell, but containing in optical section a granular 

 mass in which are three typical bird's-eye bodies, and at o' a group of 

 granules in lively oscillation ; 3, another epithelial cell, the nucleus 

 of which is not seen, and which contains two highly refracting inclu- 

 sions ; 4, a free body of similar optical characters to the inclusions 

 in 3 ; 5 and 6, structures resembling an epithelial cell in size, but 

 containing large globules of a bright greenish appearance, and at o 

 and o' groups of smaller globules in oscillation ; 7 and 8, small bodies 

 resembling parts of 5 and 6, lively oscillation in one, and oscillation 

 and a greenish nuclear body in the other ; 9, a large body, the pale 

 central mass of which is not shown, but globules and granules and a 

 few wavy lines are seen on the surface ; 10 and 11 are the same body, 

 10 as seen at 7.20 p.m., and 11 as seen at 10.45 p.m., when the prepara- 

 tion has cooled down. When first seen, there was a group of oscillating 

 granules, o, and a single greenish curved structure to the left of them ; 

 later, the preparation having cooled down, the oscillating granules 

 had disappeared, and the body seemed to have divided into two.
