exaggeration : there is stable combination, something analogous 

 to what takes place when the globules are in contact with the 

 oxyde of carbon, their special poison : the globule then loses its 

 precious osmotic qualities ; it is killed. ^ 



6.-0/ the White Globules of th« Blood. 



The white globules of the blood, or leucocytes, are pale spherical 

 globules, sarcodie, amoeboidal, having a diameter of 0""°, 008 to 

 O""", 014. 



Water and acetic acid pale them and enable us to perceive from 

 one to four granulous masses or nuclei. In the foetus the substance 

 of the leucocyte is less dense, and not granulous ; we see 

 therein one or two granulous nuclei. We find also in the blood 

 free or globuline nuclei from 0°™, 003, to O"" 005 in diameter, 

 granulous, without nucleoles. 



In the blood of Man they are in, the proportion of about 1 to 

 300 red globules : but we meet with them in greater number in 

 woman (1 to 250). They are the more numerous the younger 

 the person is. 



Prom one to two years old . . . . 1 in 100 



Newborn children 1 in 100 to 130 



Human embryon 1 in 80 to lOO' 



We thus see that in relation to the number of leucocytes the 

 woman takes position anew between the man and the infant.^ 



^ The proteiic matters of the globule differ completely from the surroimdiug 

 fibrine. They have even their special inorgamc compounds. The alkaline 

 phosphates predominate in the globules, and have especially a potaasio base. 

 In the serum, soda and lime hold sway. The globule contains ten times more 

 phosphates, two times less chlorure, ten times more potash, and three times 

 less soda, lime, and magnesia than serum. 



"We likewise behold the predominance therein of fats, especially of phos- 

 phorised fats, analogous to those of the nervose substance. 



Lastly, we know that the iron contained in the blood ia entirely confined to 

 the globules. Besides, the substance of the globule, though albuminoidaL, is 

 cryateUisable. (6. S^e, Du Scmg et dea Animies.)
