The leucocytosis was, in this case, quite tran- 

 sient, followed by a marked leucopenia. 



During the course of an attack, we may have

Billet (Fig. 62), who has traced out hourly 

 the relation of the leucocyte curve to the tempera- 

 ture curve, has shewn that in regular curves of 

 the tertian or quartan type, the leucocytic curve 

 follows closely the variations in the temperature. 

 Thus, before the febrile attack in a quartan, there 



may be a leucopenia represented by '^=j^
