Explanation of Diagram. 
The Sacculiiia fat-chains are represented by the linked half-circles 
on the left, those of the liver on the right. Into them are fitted 
the fat-molecnles (f.). Floating free in the blood a proteid 
molecule (Pd is represented which carries two fat-link side- 
chains L. In P., two of the fat -links have seized on fat- 
molecnles in the liver and are detaching them. The passage 
of fat and fat-link combinations, F L. from liver to Sacculiiia 
is indicated by the arrows A, a, a. The fat-molecules are taken 
up by the Sacculiiia side-chains, and the free fat-links are 
libsrated into the blood, L. They pass back to the liver as 
indicated by the arrows b, b, b, and fix onto new fat-molecules 
in the liver, which they detach and carry again to the Sacculiiia 
(arrows c, c, c). This continued process leads to regeneration 
of new fat -chains with fat in the liver, indicated at f.,, which 
Will be attacked by fresh fat-links, derived either from the 
above process or from new proteid molecules, P;^.
