It is this ratio - n VS that it is important to 
RC 
determine, for unless the red cells are counted as well 
as the white, little value attaches to the leucocytic 
value. 
In malaria, we find that we get changes of the 
following kinds :— 
(1) ii a.m., rigor. Red cells = 2,900,000. 
White cells 10,000 - 
i,e . 9 leucocytosis. 
(2) 11.30 a.m., rigor completed 
i.e . 9 leucopenia. 
(3) 2 p.m., temperature 38*2° 
i.e . 9 increased leucopenia.

The leucocytosis was, in this case, quite transient, 
followed by a marked leucopenia. 
During the course of an attack, we may have 
changes of this kind :—

parasites appear in the blood, instead of
