from their food, a fact which explains the contradictory state- 
ments as to the existence of fermentable matter in the blood.

.) Sanson was immediately followed by Bernarp,* who 
asserted that this animal starch existed only in the liver, His 
experiments show that when rabbits are fed on carrots a 
_ large quantity of glycogenic matter is found in the liver, but 
none in any other organ. When the animal is fed on grain, the 
case is more complicated, as soluble starch colorable by iodine 
is then carried into the body. In a former memoir, it was 
stated that starchy matters did not pass into the blood as dex- 
noticed: I. The formation of glycogenic matter in the liver is 
constant, and is entirely independent of the external supply of 
dextrin or sugar. The blood of a rabbit fed for 3 or 4 days on 
wheat or oats contains dextrin; but this is not true with an 
starch; whenever the an 
food is taken as usual
