3. The average number of leucocytes was 10.389 per cubic 

 millimeter. 



4. The average specific gravity found w^as 1.0532. 



5. The relative volume of corpuscles to plasma was found to 

 be 29.1 per cent of corpuscles to 70.9 per cent of plasma. 



6. The average time for complete coagulation of the blood v^as 

 found to be three minutes and sixteen seconds plus. 



7. The following five varieties of leucocytes were found in the 

 peripheral blood : 



(a) Lymphocytes. Average size, 7.3 microns in diameter; 

 average number per cubic millimeter, 5.049. They comprise 

 48.5 per cent of all leucocytes. 



(b) Large mononuclears. Average diameter, 10.8 microns; 

 average number per cubic millimeter, 484. They comprise 4.6 

 per cent of all leucocytes.
