Cuart 1. This chart illustrates the remarkable recovery of an animal 
when fed lactose in the ration. During the first period the animal received 
a ration consisting of oat meal and a salt mixture and whole milk. The 
salt mixture consisted of inorganic elements in the same proportions as 
found in orange juice, but acetic acid was put into the mixture in place 
of citric acid. It was shown in our earlier paper that this same salt mix- 
ture, but containing citric instead of acetic acid, prevented the develop- 
ment of scurvy in a diet of rolled oats and heated carrots. During the 
second period the animal was given a ration consisting of rolled oats 80 
and lactose 20, plus whole milk. At the beginning of the lactose feeding 
the animal was in a most miserable condition. It was very weak, moved 
about with great difficulty, and was very sensitive. After the lactose was 
introduced into the ration the animal gained in weight rapidly and showed 
marked improvement. All symptoms of scurvy disappeared except for a 
slight swelling at the knee joints. Postmortem examination failed to re- 
veal the characteristic lesions of scurvy.
