the leucocytes reach or exceed 20,000 it is nearly always due to 

 complications (pleuritis, peritonitis, pneumonia). Ewing supports 

 Turk's statement. When the leucocytes do not exceed the normal 

 limit, there is little change in the proportion of the varieties; but 

 with distinct leucocytosis, there is an absolute increase in the 

 polymorphs. The eosinophiles are scanty or may be absent during 

 the very early stages, but later are present in moderate numbers. 

 After defervescence the eosins are usually increased. 



Meier reports a case of muscular rheumatism in a mare, five 

 and one-half years old, with 8,420,000 red corpuscles, 90% hemo- 

 globin, and 20,600 leucocytes, of which there were 8.1% lym- 

 phocytes, 2.5% large mononuclears, and 89.3% polymorphonu- 

 clears. 



Dr. Ward Giltner, in a personal communication which he has 

 kindly permitted me to use, gives the counts in a gelding about 15 

 years old, taken with acute inflammatory rheumatism. On Nov. 

 9th, with a temperature of 105° F., there were 5,250,000 red cor- 

 puscles and 20,000 leucocytes, of which 2.6% were lymphocytes, 

 three per cent, large mononuclears and 94.4% polymorphs. No 

 eosins were found. Two days later the animal was much improved ; 

 eosins were present in normal numbers. On Dec. 19th, the disease 

 had changed into the chronic form; the horse was down, unable to 

 rise. There were 6,200,000 red corpuscles, 11,000 leucocytes and 

 70% hemoglobin. Of the leucocytes 13.6% were lymphocytes, 

 one per cent, large mononuclears, 84.8% polymorphs, 0.4% eosins 

 and 0.2% mast cells. The horse died the following day, the post- 

 mortem showing lesions of articular rheumatism, ulcers on the 

 articular cartilages and fibrosis of left biceps.
