The red corpuscles vary from about five to eight millions. The 

 average in this country has been found to be about six millions. 

 WVtzl found an average of seven millions (9 cattle). The hemo- 

 globin ranges from 45 to 85 with an average of 60 to 65. Hibbard 

 and Xeal found an average of seven million red corpuscles and 

 97 per cent hemoglobin in five yearling heifers.
