Of the solids the most important is Hcemoglobin, the substance to 

 liich the blood owes its color. It constitutes, as will be seen from the 

 appended Table, more than 90 per cent, of the organic matter of the 

 corpuscles. Besides haemoglobin there are proteid : and fatty matters, the 

 former chiefly consisting of globulins, and the latter of cholesterin and 

 lecithin.
