RHEUMATISM 



There are but few cases reported in animals in which examina- 

 tions of the blood have been made. In man there is an oligo- 

 cythemia in some cases. Cabot in 163 cases had 13 with less than 

 4,000,000 red corpuscles. The lowest count was 2,528,000 with 

 45% hemoglobin. The average number for the entire scries was 

 4,300,000. The hemoglobin suffers more than the red corpuscles. 

 In Cabot's cases the average was 63% with a color index of .73. 

 The fibrin is much increased. There is usually a moderate leu- 

 cocytosis but in mild cases without exudation there is usually no 

 increase in the leucocytes. The average number of leucocytes in 

 243 eases reported by Cabot was 13,800. Turk insists that when
