314 THE BLOOD. [CHAP. XXVII. 



and spleen the diminution in the coloured particles is accompanied 

 hy a remarkable increase in the number of the colourless particles. 

 Some cases of this condition of blood have lately been collected by 

 Professor J. H. Bennett, who proposes for the name Leucocythemia 

 \evtcos, white; AJUTOS, a cell; alpa, blood).* 



The fatty matters of the blood are sometimes increased in 

 quantity apparently from non-elimination. Under these circum- 

 stances the serum becomes quite milky, an appearance which is 

 quite characteristic of this state of blood, and may be removed by 

 ether. We have already alluded (p. 296) to the milkiness which 

 follows the ingestion of fatty food, but which cannot be regarded as 

 abnormal. 



There is a condition of blood to which F. Simon has given the 

 name spancemia (a-Travos, poor), and which is popularly called poor 

 Hood. This is characterized by changes in the quality rather than 

 in the quantity of the blood-constituents, and especially, perhaps, in 

 the quality of the fibrine. When the blood is in this state, haemor- 

 rhages are of frequent occurrence, owing, probably, to the imperfect 

 manner in which the coats of the blood-vessels are nourished. Pur-, 

 pura and scurvy are well known diseases, of which the prominent 

 feature consists in this poorness of blood. In the former malady, we 

 have found the blood corpuscles shrivelled, and even disintegrated;^ 

 but it is difficult to determine whether this was due to a defect in 

 their mode of generation and development, or to a diminished spe- 

 cific gravity of the serum favourable to its endosmose by them.J
