The material existing in the liver, which is the source of the production of the sugar, 
is itself formed from sugar and its ally, starch. Dogs fed upon a diet abounding in 
starchy and saccharine materials have relatively very much larger livers, and livers 
strikingly richer in amyloid substance, than dogs fed upon a purely animal diet. In the 
rabbit fasting, the liver is exceedingly small and devoid of amyloid substance ; whilst in 
the rabbit kept on starch and sugar only, the liver is large and exceedingly rich in 
amyloid substance. 
In the transformation of amyloid substance into sugar in the liver after death, the 
production of one part of sugar is accompanied with the loss of 1'54 of amyloid sub- 
stance as the average of four analyses.
