 more important are those of Virchow, Hughes 

 Bennett, Vidal, Huss, Ehrlich, and Hosier." 

 Omitting what is not necessary for the general 

 reader, and merely noting one remark under DIAG- 

 NOSIS, that " if the proportion of white corpuscles to 

 red is greater than one to twenty, the case is certainly 

 one of leucocythaemia." 



I pass on to the prognosis, which I quote in full. 



" PEOGNOSIS. The prognosis of a disease 

 which depends on a primary affection of the 

 blood-forming organs is necessarily most grave. 

 No means of arresting the progress of the 

 developed disease has yet been discovered. 

 The immediate prognosis is less serious in pro- 

 portion as the evidence of organic changes in 

 the blood-forming organs is slight and in pro-

 Neither age, sex, nor causation afford prog- 

 nostic information. The greater the number 

 of white corpuscles and the deficiency of red, 

 as ascertained by counting, the worse the prog- 

 nosis. The size of the spleen alone affords 

 little information. Haemorrhages are of grave 

 augury, but epistaxis [nose-bleeding] least so." 

 I submit that in the above quotations (and quota- 

 tions of similar import might be given to an extent 

 only limited by the patience of the reader), we have 

 a clear prima facie case against the leucocyte, that it 

 is an invariable accessory to disease, and that of the 

 most serious and deadly sort. 



Let me again remind the reader that the above quo- 

 tations are from writers who, besides being eminent
