iv THE BLOOD: FORMED CONSTITUENTS 121 



water 60 grins., acetic acid 3 grnis. In 5-10 minutes the cover-glasses are taken 

 out of the haematoxylin, washed in water, and stained for the second time by 

 dipping them for a few moments into a 1 per cent solution of eosin. They 

 are then washed again in distilled water, wiped at the edges with filter-paper, 

 dried over the i flame, and mounted on the slide with a drop of Canada balsam 

 dissolved in xylol. 



The nuclei and blood-platelets stain blue with the haematoxylin, the 

 protoplasm pink with the eosin. 



A copious literature has recently sprung up in regard to 

 osmotic phenomena, and the resistance of the erythrocytes to 

 yielding their haemoglobin, when brought into salt solutions of 

 different concentrations. Since, however, this subject is intimately 

 connected with the physico-chemical structure of the blood 

 plasma, we shall consider it in the next chapter. 



The important question of the origin, formation, and 

 destruction of Erythrocytes and Leucocytes will be discussed in 

 treating of the function of the haematopoietic and haematolytic 



organs.
